Purchased a muzzle break for my Draco a few weeks ago and today was the first time I was able to try it out. All I have to do is walk to back of property and let loose, but with the heat and health issue had to wait until today. Took my AK47 Rommy, Bushmaster .223/5.56, and the Draco to try to kill a tree I don't like. The Draco accepted a Tapco 20rd mag with no problems and except for being loud as heck in rapid fire I was able to keep it on target. No rise and darn near no real felt recoil either so guess this is a keeper. Only issue was on the Rommy AK the Tapco mag failed to feed first round and about the third rd, using my 30 and 40 rd metal mags the Rommy fed perfect. Bushmaster - Well all I can say is GREAT.
