Consistent accuracy is what all shooters are ultimately looking for when hunting or target shooting. In order to get perfect accuracy with every shot, it’s necessary to glas bed your rifles to get an absolutely skin tight fit between the barrel, action, and stock. I’ve been building a Remington 700 and wanted to make sure that the rifle would be an absolute tack driver. Since all of the parts I’ve been using have come from Brownells, the bedding job on the H.S. Precision stock I bought would be done using our great Acraglas Gel (#081-014-004).
Yes, I know, the H.S. Precision stock has a bedding block. But, bedding
blocks have manufacturing tolerances and so do Remington actions. Plus,
the term “drop-in” means everything about the stock has to
be left just a whisker “loose” so if there are manufacturing
variations, the action will still actually drop in. For the price of a
bedding kit, we thought it would be interesting to see if we could improve
the accuracy, even a little bit, by removing that little bit of slop.
Here’s a list of the products we took out of stock to do the job.
We already had a small, Ballpeen
Hammer (#956-100-002) to drive the pin punch, a Pistol
Bench Block (#498-100-200) and a Brownells
Multi-Vise (#080-000-019) with set of Red,
Super Hold Vise Jaws (#852-002-100) modified to slip over the vise’s moveable
jaw bar. Any decent-sized vise will work; just pad the jaws to protect
the stock. Of course, we like the Multi-Vise.
Other products you’ll need are:
Gel Kit (#081-014-004) – the two gun kit.
Bedding Block (#080-000-206) for Remington 700
2" Wide Bedding/Masking tape (#084-092-001)
A Surgical Tubing (#084-076-001)
Pin Punch Set (#080-507-000)
Guide Screws (#319-415-070) – a tremendous help!
Cleaner/Degreaser (#083-060-024) – a big aerosol can.
Cotton Applicators (#885-861-500) (big "Q-tips" with long, wood handles
- do all sorts of things with them, you'll see)
Shop Cloths (#084-086-001), one dozen – white are available, we picked the
red ’cause they look great in pictures.
From the grocery store:
Take everything apart; the scope and rings can come off as a unit, pull
the bolt out of the action and take the barreled action out of the stock.
If the magazine box isn’t screwed to the action, wiggle it out of
its recess. Taking the trigger out is easy, but, if you don’t look
at things carefully, putting it back in could require a look at the schematics
on the Brownells web site. Thank goodness, for my sake, those are there.
Driving out the front trigger group pin.
Lay the barreled action on the bench block, left side down. Start with
the rear pin and line it up over one of the holes in the bench block.
Drive it out from the right side, to the left side, with the .090”
pin punch and the small hammer. Catch the little mousetrap bolt stop spring,
and slip the bolt stop out. Put the stop, pin and spring in some sort
of container. Line up the front pin over the bench block hole, and drive
it out. Turn the action up and slip the trigger group out. Don’t
let the trigger group turn upside down. The sear is now loose and it,
and its spring, can fall out. They’re easy enough to put back; finding
that spring on the shop floor is the problem. Put the trigger group and
the front pin into your small parts container.
Position the Trigger Bedding Block.
Secure the Bedding Block.
Slide the Trigger Bedding Block into the trigger recess and lock it in
place with the little steel plate and the socket head screw. Now, use
the TCE to degrease the action and rear 4”, or so, of the barrel.
Grab the modeling clay and fill in the trigger group pin holes, the openings
in front of and behind the Trigger Bedding Block, the
bolt stop slot, and any other opening on the bottom side of the action.
EXCEPT, don’t fill in the front and rear action screw holes. Smooth
it all out, nice and level with the metal surfaces of the action.
Fill all recesses and pin holes with modeling clay.
Next up, the recoil lug. The vinyl Bedding Tape really
shines here. Cut an inch and half wide (roughly) by three-inch long strip
and lay it across the front edge of the recoil lug and let it fold up,
along the barrel. Use something square edged with a fairly sharp corner,
like the back of a closed pocket knife, to push and stretch the vinyl
tape to make it follow the curve of the barrel where it meets the recoil
lug. Once the tape is shaped and stuck down tightly trim the excess off
the recoil lug. You just want a layer on the front face to make it a bit
easier to get the lug to slide out of the recess. Use the light, ballpeen
hammer to tap along the edge where the tape meets the edges of
the lug. Let the hammer kind of bounce lightly and work back and forth
across each edge until the lug’s edge cuts through the tape. Peel
the extra off. Trim the tape along the joint between barrel and lug so
all that’s left is a perfect cover over the front of the recoil
Stretch the vinyl tape across the
lug and up the barrel.
Tapping with the hammer will
cut the tape cleanly.
Open the Acraglas Gel kit and get out the small bottle of Release Agent.
Grab one of the Cotton Applicators and dunk it in. Swab the bottom of
the action, all of the Trigger Bedding Block and up, around the sides
of the action, the magazine box opening, the entire top of the rear tang
area, all sides of the lug (including the tape) plus the tape on the barrel.
Run it up the sides farther than you think you need to; bedding compound
seems to find its way onto everything – even Gel, which doesn’t
run. One of those facts of life that can’t be explained.
Apply Release Agent liberally, even where you don’t think
you need it.
Set the barreled action aside so the Release Agent can dry and clamp
the butt section of the stock, gently, in the Multi-Vise. Get the modeling
clay out and fill in the bolt handle cut. Cover about four inches of barrel
channel ahead of the lug recess with tape, and tape along the top edges
of the stock and around the rear tang. Next, make a clay worm about two
to three inches long and 1/8” in diameter. Lay it on top of the
tape, right in front of the lug recess. It’ll act as a dam to keep
the Gel that squishes out from working its way down the barrel channel.
Back to the barreled action. Here’s a neat trick Marc showed me.
Wrap the Inletting Guide Screws with bedding tape. Two or three times
around should do. This will make sure there’s clearance around the
screws and that no bedding will get into the holes and create an extra
recoil lug. Be careful, the first time I tried it, I got too much tape
on and the screws wouldn’t fit the holes at all. Marc took off a
couple of layers, leaving a bit of clearance. Screw the Guide Screws into
the action, give them, and their tape a thorough coating of Release Agent,
along with adding a second coat to the rest of the action – that
means cover everything you did before, again. Get the Release Agent up,
around the sides of the action and on top of the rear tang – did
I mention that bedding compound can find its way anyplace?
It’s time to mix the Acraglas Gel®. Have a
bottle of vinegar close by to clean the measuring spoon, and your hands,
during and after the mixing process. Dig a glob of the white resin out
of the jar with the measuring spoon. Grab the tongue depressor and pack
the resin into the spoon to eliminate any voids. Now, scrape the excess
resin off the spoon with the tongue depressor. Return the extra to the
resin jar. With your third hand, set the mixing cup on the bench, upside
down. Scoop the measured resin out of the spoon and put it in the dished,
outside, bottom of the cup. Mixing on the bottom makes it easier to get
all the resin and hardener mixed together, plus it’s really easy
to pop the left over, setup Gel off the bottom before the next project.
Wet a paper towel with vinegar and clean the measuring spoon thoroughly.
Dry it with another towel and dig into the Hardener jar. Do the same,
pack, level, scrape and scoop routine.
Clean the scoop with vinegar.
Scooping the hardener out of the jar.
Scrape excess back into the jar.
Poke a pin hole in the black dye packet and add two or three drops to
the unmixed Gel. Don’t overdue the dye, add only a drop at a time.
Use just enough to get the perfect color you want. Use the tongue depressor
to stir, fold, and mix the dye and the Gel until it turns jet black and
no resin or hardener remains unmixed.
Add a few drops of dye; go easy!
Take a deep breath and start spreading the Gel into the stock. One glop
goes in the recoil lug recess. You don’t have to fill the recoil
lug area, there’s not that much space to take up. Put a layer along
the inside of the stock where the sides of the action rest, and another
coat where the rear tang sets.
If the butt of the stock isn’t clamped into your bench vise, with
a support under the forend, do that now. If you have a friend around you
can skip the vise and make him/her hold the stock. Carefully slide the
barreled action into place, and squeeze it down, into the stock with firm
hands pressure, getting it all properly lined up.
Dropping the barreled action into the stock.
Grab the Surgical Tubing and thoroughly wrap the stock and action with
it, stretching the tubing for each revolution. Set the gun aside, just
make sure there’s no stress on the barrel or action that could change
Looks pretty ugly wrapped with surgical tubing.
Clean up the measuring cup with vinegar, pitch the tongue depressor,
and clean up the area. Now, walk away and do something else for three
to four hours.
While you’re ignoring the temptation to mess with the gun, find
a scrap of wood or plastic and make a sharp edged “knife”
or scraper. Once the three to four hours, (okay, three hours and two minutes)
is up, unwrap the surgical tubing. DON’T try to take the barreled
action out of the stock! Use your plastic/wood knife to cut away the rubbery
bedding material that has squeezed up out of the stock. What you’re
doing here is avoiding a mechanical lock. Cut along the top edges of the
stock and especially around the rear tang. The tang can’t set “in”
the bedding, it should only rest “on” the bedding.
Once you’ve cleared away all the excess bedding, you’ll know
how much the Gel has set up. Depending upon the temperature and humidity,
three hours may be fine for the next step; you might have to wait five
hours if the room temperature is low and the humidity is high. The step
we’re talking about is taking the barreled action out of the stock
for inside cleanup.
Flip the gun over, make sure there’s something soft underneath,
and start working the barreled action out of the stock. Since everything
is at zero clearance, this isn’t easy. Go slowly and kind of wiggle
it out a bit at a time. Alternately pressing down on the barrel, then
on the action (stick a wood dowel inside the bolt raceway) and, sometimes,
even a thump on the inletting guide screws with a plastic hammer is necessary.
Depending on how tightly those tape-wrapped screws fit in their holes,
it can help to unscrew them completely from the action.
Once the barreled action is out of the stock, start cutting away the Gel
that has snuck into the magazine box recess, around the trigger bedding
block, etc. If you cut down to the aluminum block, all the way a round,
you’ll be in good shape. If you wait until the bedding has set completely,
you’ll need to use something like a Dremel or Foredom tool, a die
grinder or chisels and files. Peel the tape off the front of the recoil
lug and put the barreled action back into the stock for at least another
eight to twelve hours.
Gel reaches full strength in 24 hours, but you can pull the barreled action
out again around 18 hours and finish the clean up. Take all the clay filler
out of the action and the stock. The round, wood stems of the cotton swabs
can help dig down into the recesses, and poke through the screw and pin
holes; soak the cotton end with TCE and wipe the surfaces, peel the tape
out of the barrel channel, and get all the release agent off the metal.
If you haven’t done it already, pull the Guide Screws out and take
the Trigger Bedding Block off. Once everything’s
clean, give the metal a light coat of oil and start putting it back together.
Start removing modeling clay, bedding tape and
Compound that has oozed into various places.
When you start putting the trigger group back in, don’t
turn it upside down. The sear and its spring can fall out easily. Putting
the bolt release and its spring back in is the trickiest part, I found.
Get the trigger group in place and drive the front pin in, all the way.
Clamp the action into the vise, otherwise you’ll need at least three
hands (four would be better).
Hook the short leg of the spring over the receiver, behind the trigger
group. Hold the round loop in the recess, drop the bolt stop into its
recess next to the trigger group and hook the long leg of the spring over
the front of the bolt stop. Now, try to line up the rear pin through all
the pieces and tap it into place. I messed around for quite a while, swearing,
dropping pieces and getting more frustrated until I finally stopped, went
to the tool box and used the middle size replaceable pin punch as a slave
pin and followed it through with the pin. If you have access to the Brownells
web site, find the Remington
700 schematic and you’ll see how things fit.
Put the magazine box into its recess, add the follower and spring. The
spring kind of gets a weird angle to it and can goof up your reassembly
if you don’t make sure the stock goes over it correctly. Get the
action into the stock, or the stock onto the action, put the triggerguard
on, the screws in and tighten them down, snugly.
Turn the gun back over, put the bolt in and check for correct function.
I missed cutting out a bit of Gel near the bolt stop lever and it was
just enough to keep it from working. I took the barreled action back out
of the stock, dropped the follower and magazine spring on the floor, and
found out the bolt stop worked once it was free of the stock. All it took
was the tip of my pocket knife to flick the piece of Gel away. Back together,
flip the gun over and set the scope back on. Here’s another screw
I didn’t have a socket wrench set handy to tighten the TPS rings,
so I grabbed a small, adjustable (Crescent) wrench. Kind of had to work
it in at an angle and twist. I heard something scrape and stopped. Of
course that was too late to avoid the gouge the tip of the wrench jaws
put in the ring’s finish. Take the time to get the right
Even though there was a lot of work involved with this project, I’m really glad that I decided to do it myself. I guess I’m like a lot of you…nothing beats the satisfaction of doing a good “hands on” job yourself and then being able to enjoy the fruits of your labor. Since finishing up, I’ve completed the rifle and gone out the range. It’s performed flawlessly so far and the accuracy is simply amazing. Remember, you can do a bedding job yourself at home, all it takes is a little patience and a little desire and a few products from Brownells.
