Peeoii - got your reply via google mail but not seeing it here. “How tight are your muzzle devices? 20ft lbs and higher cause barrel constriction. AR15 tech tips in under 8 mins has a video “the dangers of over torquing flash hiders” very informative my groups got tighter by .5 moa when I loosened my flash hider from 35 ft pounds to 17ft lbs and applied slight amount rocksett”. Per Barry Dueck of Surefire, going over 30 ft lbs can compress the muzzle, so I do not go over 30. For bolt guns, I will use 20 ft lbs and for self loaders, I’ll go 25 but no more than 30. For a bolt gun I’ll use 1 drop of Rocksett and for a self loader I’ll use 3 drops. I always dry fit the parts and check with an alignment rod before committing installing with Rocksett. For a AR, you’ll want to use a Geissele reaction rod, or something similar to keep the barreled upper from rotating. Never use a crush washer with a can. If you are using shims to time a muzzle device, dry fit everything prior to using Rocksett. Hope that helps.
AAC Blackout 3 prong FH. They are about 4.4 oz and quite effective at killing flash signature. There are many similar FH’s on the market. Anything with 3 or 4 fairly long tines will work well. Some people don’t like the ring that they produce sounds like a tuning fork when you fire a shot. Some other, similar FH’s do this and some do not. You can modify them so they don’t ring, but the ring doesn’t bug me.
@@forcesolutions4154 I appreciate the response, I’m not getting any of those rods because I have been looking at getting a bore straightness gauge from PTG, I’m also looking into muzzle erosion, muzzle concentricity and a few pin gauges
@@forcesolutions4154 thanks man, I was thinking about the Geissele though if I were to get one, is it only if you’re planning on mounting a suppressor? or is it good for flash hiders/breaks as well?
In response to a question asking why I didn’t use a 0.218” rod in the earlier videos . In case you can’t couldn’t tell, I am not a fan of using the McMaster rods as gauges for barrel/muzzle device/suppressor alignment. They are a very high quality item, no doubt. I am not criticizing McMaster. As the videos show, a 0.217” diameter rod is the best one to use for this purpose, and a 0.212” diameter rod is inadequate and I recommend against using them.
