[ARCHIVED THREAD] - Question for Predatober owners who have installed muzzle brakes. update in op

Posted: 1/14/2017 5:54:52 PM EDT

My new rifle came in but TranQuilo muzzle brake was not installed. I need to remove flash hider and install the brake.
Was the flash hider hard to remove or just the crush washer. What upper block do I need to fit a 7.62 PredatOBR to put in a vice.
Also how do you time it. By eye or does it have to be perfect.

which multi tool will fit the TranQuilo brake.

Update since no one is reading the thread before posting

Well I bit the bullet and got 2 Geissele Reaction Rods and chased down a snap on truck for a 15/16 crowfoot for my torque wrench .
Super friendly people to deal with just like the help I have received from Mark's crew.
I also got a Wheeler Engineering Delta Series Upper Receiver & Picatinny Rail Vise Block for barrel nut install on future builds.
LaRue said use red loctite 242. on the brake.

Well i'v read the wrong upper block is bad. LaRue has billet uppers that may not fit properly in some blocks. Then add this is a 7.62 upper

My block is a pillow top mattress on one side and my knee on the other

I once witnessed a Socom Surefire brake taken off a OBR Lite SBR using the floor, a wrench and leverage, that was then proceeded by a install of a Surefire MB556AR Brake that also got perfectly timed....

I use a DPMS flipper action block to support the rifle while removing a muzzle device. It should be fairly easy to remove the bird cage / washer and then install the TQ brake using a 15/16ths box wrench. Make sure you review the instructions that came with the TQ brake, only use the TQ SS shims and once you get it timed, use green Loctite to secure it to the barrel.

ETA - I've also been know to use a field expedient method which involves rifle on carpeted floor, foot (lightly) on rail and mag well, and then wrench the bird cage off, YMMV.

You could take the handguard off the upper to expose the barrel....then put the barrel in a vice with soft jaws.......then wrench off the brake. It works if you work it.

Bird cage is just a crush washer btw

Also third on the floor method. The brakes don't get that much torque and I would use rocket on it

Heat + wrench = old brake off. New ASR brake + shim washers + locktite + wrench = Omega compatible rifle. This will soon be Tranquilo brake + shim washers + locktite + wrench = Tranquilo compatible rifle as soon as Tranquilo is out of jail.

Clamshell for handguard installation. Reaction Rod for muzzle device. Some people do either installation with either tool, but you run some small risks.

Reaction rod if available. KAC Knight Stick does the same thing.

I have two of these I sandwich the barrel between and vise it.

I've used the magpul bev block and it works fine.

I always use the JP block doing my stuff. I assume it fits my Obr. Haven't checked.

I use a magpul bev block or a combo of my knees and the floor.

Removing an A2 is easy.

Check weapon is unloaded
Sip beer
Put gun between your legs facing out
Sip beer
Stick giant screw driver in slot on A2
Sip beer
Use giant screwdriver wrench thing to spin A2 counter clockwise
Finish beer
