3 BUCC INC. - AR-15/308AR Flat Top Brass Catcher Black

I have used few times on YHM 5.56 upper w an ACOG/Larue mounted. Works perfectly. sturdy, not flimsy, railmount is a very tough plastic (?) Mount Fit was very tight on the rails - had to tap to install but also a nice snug fit. Did not move after mounting. 2 rails "friction fit" into the mounted holder. tight fit. All cases were ejected into bag, no feed, jam issues. I put a piece of crumpled light cardboard into the bag - to give shape and have brass strike1st, then drop, fwiw.

I use this brass catcher when target shooting. I have had few different kinds of brass catchers that caused all kinds of problems. This is the best one so far. It works so well that I am not aware that it is attached to the rifle. It holds 50 5.56 brass casing with no problem. Once in a while one casing may sneak through, but its not often. One issue that may occur that you need to look and verify is the mounting on a flattop, make sure you have clearance with your scope and rings.

Great product ! I bought one of these a couple of months ago, and could not believe how well it fits and works on my AR 15s. The only negative is that you cannot buy the attachment for the picatinny rail so that the catcher can be used for more than one gun. On my long range AR, the large scope made it impossible to remove the brass catcher attachment without removing the scope, the reason for purchasing another. It's not cheap, but if you buy cheap first, you'll regret not buying this one.

The fit to the upper is nice. I did have to open up the slot in the mount to fit on the rail however I believe that is because the riser was cheap and I think its is out of spec. It fit on to the rail that was on the upper perfectly. It caught 90 rounds without fail. I think it will catch 100 rounds easily. It matches up to the opening nicely with the riser on and did exactly what it is supposed to do.

Left handed shooters don't get hot shells hitting your ear. Also great at the ranges for collecting your shells no stoupping and sweeping with bad brooms. I reload so collecting shells are so easy. Being left handed hot shells don't hit your ear muffs or the shooter to your right.clean and quiet way of collecting your brass. When I'm at the range I am there to shoot not hunt and pick up brass.
