| I have a 20"barrel with rifle length gas system,and carbine buffer/spring(collapsible stock). Will a heavier buffer reduce muzzle rise. Would I need to use stiffer spring also? |

It could slow down your BCG enough to have it stop cycling.
M16A2 rearward BCG velocity in 160 inches per second. M4 rearward BCG velocity is 240 inches per second. That is why there is so much attention being paid to carbine stuff like H, H2 T2 buffers, et. I might be better to go with a comp on the end of the gun. But change ONE THING AT A TIME. That way you will know what fouled up your operation. Noveski or krink can muzzle device have been the best I have tried. I don; like the side blast on shooting buddies. |

Yes I've been around some comps and seen that they work, just a bit obnoxious. I read a review on the MGI buffer and it SOUNDED good,but costs more than any of the comps. Has anyone tried the Griffin Armament M4SD 2 flash hider/comp ? A good comp does not have to be stupid loud. It's the brake part of them that really does this. We really could use a few more comp options on the market that don't have brakes built in to them. Brakes on ar's are really not needed in my opinion. I'm really surprised you have enough muzzle flip on a 20"er to even be worried about it. |

Yes I should just practice more,but I have seen comped guns that don't lift at all. Comp guns usually run a whole new operating system. Low mass carrier, new springs, tuned buffer, adjustable gas block and some sort of comp or brake combo. Also keep in mind the shooters skill level. I went the adjustable gas route with a good comp. The comp pushes down on the muzzle enough for me to time the gas to literally eliminate muzzle flip. I used a light weight spring on a heavier buffer and was able to set the gas on the block just enough to keep the muzzle from diving. I still get a little lateral movement but I think its more my technique than anything. |

Really? I was under the impression that comps or flash hiders did not affect gas systems enough to worry about. I realize that suppressors change the operation of the system. You are correct no need to changing any internals (no lite weight bolt carriers needed) with running comps. Just put the comp on. Also comps don't redirect gas down they break it up (dump it) as it goes out. Shooters tend to play with buffer / spring weights and bolt carriers after putting comps on just to really fine tune the felt recoil pulse. if you are running a carbine length gas system just go with a H2 or better yet Spikes T2 buffer. |
