XDman Posted April 23, 2011 Share Posted April 23, 2011 OK, I am new to AR's except some plinking, but would like to change the factory birdcage with a Miculik comp on my CMMG. Besides the comp, what other parts, and what tools would I need to accomplish the changeover? Link to comment Share on other sites More sharing options...
EkuJustice Posted April 23, 2011 Share Posted April 23, 2011 Armeror's tool and either the upper receiver block or the barrel vice jaws and a vice. If your just doing the one barrel, ask around the club or a local smith. It is a pretty quick process if you have the tools but might be cheaper to have it done if you just need the one done Link to comment Share on other sites More sharing options...
AnthonyL Posted April 23, 2011 Share Posted April 23, 2011 (edited) You could buy an AR armorer's tool for $40-60 or most gun shops sell a buffer tube tool which also has a birdcage wrench built-in. I have one made by Tapco, they are very common and only cost $7-8. Nothing else is needed for the install. Do not locktite the new muzzle brake.

whistlepig Posted April 25, 2011 Share Posted April 25, 2011 If you are new to them, shoot one first and more importantly, stand beside one..... Muzzle blast is a bit more than what you may be used to. You may need the brake for what your intended use is, but if you haven't experienced it yet, the side blast can be a treat Link to comment Share on other sites More sharing options...
MarkCO Posted April 25, 2011 Share Posted April 25, 2011 (edited) Two strap wrenches will do it also. One on the barrel, one on the flash hider, maybe even a crescent wrench on the flash-hider. Edited April 25, 2011 by MarkCO Link to comment Share on other sites More sharing options...
XDman Posted April 25, 2011 Author Share Posted April 25, 2011 Wistlepig, Thanks for the comment but I already have several more powerful rifles with muzzle brakes, so I am fully aware of the sound differences. Everybody else, thanks for the comments. I will see what I can do with my tools. Link to comment Share on other sites More sharing options...
Nuke8401 Posted April 25, 2011 Share Posted April 25, 2011 My bird cage was installed with a lock nut against the bird cage just like the comp you are going to install. So if yours is the same, common hand tools will do the trick. The Miculik comp with just the locknut, no Locktite, has not moved on my rifle. Not sure if instructions came with your comp, on Jerry's video he discusses "clocking the comp" to the shooter, basically 1:00 for right handed and 11:00 for left handed as starting points, shoot and check muzzle to make sure muzzle is not moving to one side, if so rotate the comp to compensate. Muzzle blast for the shooter, almost none. Muzzle blast for innocent bystanders, awesome! David E. Link to comment Share on other sites More sharing options...
whistlepig Posted April 25, 2011 Share Posted April 25, 2011 ref tools, the most important is tha action block to hold the rifle in a vise. the correct size open end wrench works fine. Link to comment Share on other sites More sharing options...
