Love the fit and function
Put it on my Aero Precision AR-308. I have one on my CMMG AR-308 which I believe was a version 1. I like the fit of this newer version 2 even better. The position of the release with respect to my trigger finger is superior. It was easy to install and a perfect fit. Outstanding improvement, thank you Phase 5!
Ext Bolt Release
I recently built a 308 AR using primarily Aero Precision components. I have extended bolt releases on all of my AR15 rifles and I was wanting one on the 308. The Phase5 fit and functioned very well. Installation on the Aero M5 receiver was easy due to the recessed threaded pivot pin.
EBRv2/308 Extended Bolt Release by PHAS
FWIW: I bought this for my AR10 acouple wks ago and I bought 2 for my AR15s. Install was easy and it worked alright right out of the box with my billet lower but it was NOT catching the Bolt 100%, So I fit the part via a Dremel tool, PHASE 5 Heat Treat or whatever they do to make this Bolt Release/Catch Hard IS Amazing! I could not believe how TUFF this part was to mod., using a File was working but was Very, Very Slow going, which is why I broke out my Grinding, Sanding & Polishing wheels! Catch is 100% now and I will never use another "Tactical Link" (BAD lever) again.
Perect Fit
This AR Bolt Release was the answer...it solved the problem I had with the fitting of other AR Mag Bolt Release, since it was one piece it slipped in and it worked. The other AR Bolt Releases require the back mounting plate and this interferes the upper receiver. This was just the right item. Great Idea
This thing works
Works perfectly on my R25 using pmags. Easy to install and functions beautifully. Well worth the price imho.
Works beautifully.
I was a bit leery after reading some of the reviews, but still decided to use it on my build. I did make sure to polish it with 600 grit sandpaper and treated the entire lower and parts with froglube prior to assembly. When I dry fit it prior to polishing it, it was a very snug fit, and I can understand where it would cause issues. However, if you put the extra care into it beforehand, it should work phenomenally. I've put over 400 rounds (over 20 mags) through the gun, and I've never had it fail to lock the bolt back. Also, while it holds the bolt quite secure, it doesn't take much pressure to release.
Fine engineering
I found out that most SIG AR platforms will not accept the Magpul extended bolt release extension that clamps on the stock bolt release lever. I got two Phase 5 releases (5.56 and 308) and both fit on to my Sig 516 and 716. They replace the entire bolt release lever and eliminate the wobbliness felt in the Magpul clamp on version. They are a little tricky to put on due to the location of the roll pin holding it place. Be patient and have the right tool. Brownell sell a roll pin punch designed for the bolt release roll pin. Remember to put protective tape around you lower.
Handy
Most handy for locking the bolt back, with less hand movement. I have them on every rifle. Both large and small could be a little tighter fitting at the mounting location.
Not best for straight triggers
Easy to install and ingenious idea. I have this model on 2 rifles and Ive noticed on the straight trigger rifle, if you get too much finger inside the guard, up close to this device, it will give you a sharp bite. As near as I can tell its caused by the vibration from the hammer striking the lower assembly directly adjacent to the bolt stop. Use it for a learning tool to prevent using too much finger on the trigger :-)
model spec. fit
Installed on a dpms .308 and it would not hold the bolt open. Then installed on a mega mono upper and it work perfectly.
