FaRKle! Posted January 30, 2015 Report Share Posted January 30, 2015 http://www.thetruthaboutguns.com/2014/11/jeremy-s/556-muzzle-device-shootout/ Although for 5.56, I thought this was interesting. Anyone have experience with a precision armament brake?I bought one for my friend this past month.It does a good job of reducing recoil, but man does it REALLY suck to be next to it.

D.R.D. Posted January 30, 2015 Report Share Posted January 30, 2015 Did you get the 5.56 or .308? Given that guy's data, do you agree, or have you tried others that work as well or better? Quote Link to comment Share on other sites More sharing options...

Given that guy's data, do you agree, or have you tried others that work as well or better?I got him the M4-72. It only comes in 5.56. I haven't used many other 5.56 brakes (I don't like them due to the side concussion) so I can't really compare, but I wouldn't imagine it'd be a lot more noticeable than other brakes of similar design.

D.R.D. Posted January 30, 2015 Report Share Posted January 30, 2015 According to that guy, it ruled the roost. Of course, many other similar brakes weren't tested Quote Link to comment Share on other sites More sharing options...
medic83 Posted February 8, 2015 Report Share Posted February 8, 2015 (edited) On my ar 308, I use the precision armament MB/comp. It alone with the rifle length gas system, heavy buffer make it amazing to shoot all day. Very soft, easy to keep on target. On one of my ar's I just built...I put the Ferfrans CRD on it, looks bad ass. It really does what it says. U can pop it off and the MB works better. You can actually tell. With the shroud on....shooting at night is insane! I was almost blinded looking thru my aimpoint! Lol. My buddy snapped some pics and got a slo mo vid. I'll try and post them... I only have my iPad so I don't know how to post them. It wouldn't let me upload the vid. Maybe the link will workhttps://www.facebook.com/video.php?v=10206477113953637 Edited February 8, 2015 by medic83 Quote Link to comment Share on other sites More sharing options...
Cali_Ed Posted February 8, 2015 Report Share Posted February 8, 2015 You guys use loctight keep the brake in place right? Quote Link to comment Share on other sites More sharing options...
98Z5V Posted February 8, 2015 Report Share Posted February 8, 2015 NO. No Loc-Tite! Use a crush washer or peel washer if it's not going to be a suppressor host. Mount it directly to the barrel (machining might be required to time it) if it will be a suppressor host. Use RockSet if it's going to be a suppressor host.

Cali_Ed Posted February 8, 2015 Report Share Posted February 8, 2015 I'll have to take a picure of mine because mine has a black washer and then I used the shims.... Quote Link to comment Share on other sites More sharing options...

98Z5V Posted February 9, 2015 Report Share Posted February 9, 2015 ^^^ Timing shims, I have seen. Hadn't seen peel washers, though. Makes sense, they don't crush. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted February 9, 2015 Report Share Posted February 9, 2015 I've used both. Peel washers seem faster to install, since the trial and error portion is so simple, but timing shims seemed more sturdy. I'm sure they're both equally as good as each other.

survivalshop Posted February 9, 2015 Report Share Posted February 9, 2015 I had a PRI Brake custom made the fit seamlessly to the Barrel on my 20" & I made a 0.002" shim to index it & It would come loose even though it was torqued . I called PRI & asked how do they keep theirs on with out a lock washer of some sort & they said Loc tite . I used a small portion of Blue Loc-Tite & its been on there for years , still tight . It needs to come off to clean the barrel & Brake , so will put it back on the same way . Quote Link to comment Share on other sites More sharing options...
98Z5V Posted February 9, 2015 Report Share Posted February 9, 2015 You can easily generate enough heat through shooting to melt loc-tite. RockSett takes 1,500 degrees to melt, but is about the holding equivalent of blue loc-tite. Quote Link to comment Share on other sites More sharing options...
planeflyer21 Posted February 9, 2015 Report Share Posted February 9, 2015 And in one statement Tom makes obsolete my whole supply of blue loc-tite. Quote Link to comment Share on other sites More sharing options...
Matt.Cross Posted February 9, 2015 Report Share Posted February 9, 2015 And in one statement Tom makes obsolete my whole supply of blue loc-tite. You were using it exclusively for muzzle devices? :P Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted February 9, 2015 Report Share Posted February 9, 2015 I used rocksett and timing shims to put an AAC muzzle brake on my Ruger GSR. It's only hand tight, but still doesn't move. Quote Link to comment Share on other sites More sharing options...
Cali_Ed Posted February 10, 2015 Report Share Posted February 10, 2015 I'm assuming if the mb keeps slightly moving it changes poi? Quote Link to comment Share on other sites More sharing options...
survivalshop Posted February 10, 2015 Report Share Posted February 10, 2015 I'm assuming if the mb keeps slightly moving it changes poi? That's possible , could alter POI because of the effects on your shooting . Directional gas ports on the Brake , indexed incorrectly .

D.R.D. Posted February 20, 2015 Report Share Posted February 20, 2015 (edited) So, after reading the link below a little more thoroughly, it seems the following are in the top running for recoil reduction. This is based on the data he collected, as well as anecdotal evidence of other bakes/comps not included, but known for preforming very well. Precision Armament M41 and M11 LANTAC Dragon DMPS Miculek VG6 Gamma R&D MRAD Surefire SFMB SJC Titan Rolling Thunder http://www.thetruthaboutguns.com/2014/11/jeremy-s/556-muzzle-device-shootout/ Edited February 20, 2015 by D.R.D.

Cali_Ed Posted February 20, 2015 Report Share Posted February 20, 2015 M11 looks like the benny cooley, I wonder if it's worth a shot to try. Didn't see the benny cooley on the list Quote Link to comment Share on other sites More sharing options...
D.R.D. Posted February 21, 2015 Report Share Posted February 21, 2015 (edited) The M11 has 3 side ports, the Cooley only has 2. It is interesting though, that he tested the JP/ GoGun Supercomp and Jp Recoil Eliminator, but not the JP-Cooley brake. Is that cause he and JP don't think it works as well? Who knows. IT certainly could be added to the list. Based again, on many anecdotal, claims are that the SJC TItan & Rolling Thunder work better that the JP-Cooley in terms of recoil. I'm especially curious to see how they'd stack up against the inexpensive Miculek that preformed great, as well as the pricier PA, Lantac and R&D. (I know many of these are designed as comps, but as this guys data shows, there's quite a bit of crossover) Edited February 21, 2015 by D.R.D.

98Z5V Posted February 22, 2015 Report Share Posted February 22, 2015 I have a bad feeling one of these things will be in my possession soon. I've got a really bad itch to build a lightweight 16" midlength 5.56 gun... This schit hit me in the last 48 hours, too... :rant2: Quote Link to comment Share on other sites More sharing options...
