Hello everyone this is my first post. I have Windham Weaponry/Way of the Gun collaboration ar 15 bought new about 3years ago. 16” barrel mid length gas system, carbine buffer weight and CMC 3.5lb trigger all factory come in the gun. I since built a Noveske/BCM Frankenstein rifle so I understand the way the rifle works now especially with the gas buffer system balance. Now I have Frank Proctor rifle class this Friday so I have decided a couple weeks ago to upgrade my gas tube (BCM) and buffer spring and weight also (BCM) I now have tried H,H2,ST-T2. So to the problem now, last week I started zeroing the rifle and at the end I had 3 rounds left and pulled the trigger and boom out came 2 rounds. I did a visual and function check everything seemed ok, shot the last round and no problem. Started doing a search and found some test that some people say to break down the rifle cock the hammer pull the trigger let the hammer fall while keeping trigger pulled, re-cock hammer and reset trigger did this 20-30 times everything operates as it should. So I began thinking maybe it was me maybe gotten “lax” on the trigger. So yesterday went to a local indoor range to do some controlled environment zeroing last touches and I did it twice in a row. Now I was only loading three rounds at a time and once this happened I started only loading one round so people wouldn’t notice. This all happened with an H2 buffer weight if this matters? So I came home completely broke down the cmc trigger it looked like wear was on the sear. So with my class this Friday I went and bought a geissele g2s today installed it and also decided to swap buffer weight to spikes t2, just to see if it made a difference. Went and shot 50 rounds and after about 20 rounds boom 2 round burst. This rifle has the factory BCG also. Could the aftermarket buffer weights or aftermarket spring cause this.? Or even the new bcm gas tube? It seem that this occasionally happens after about 20-30 rounds, now the way I was shooting was like you would be zeroing. One shot reset trigger look through scope to see where round impacted ect. I know the whole machine gun/ government overreaching ATF argument with this but I’m more concerned with the problem and functionality of my rifle any help is greatly appreciated. Apologize for the long post. Have a great day.
