So I took the wife to a range today. We shot revolvers, in which my Servic Six trigger locked up.


But anyway I went to shoot my AR's. The Colt a4 worked great, nothing serious just shot a few rounds at 50 yards.

I got out my Serenity Arms Texas Patriot rifle. Load 5 rounds. 1,2,3, then burped out the last 2. I thought what the hell. Loaded 2 rounds, they singled just fine. Loaded 5 rounds. 1,2, the burped out the last 3.

Now this rifle came with a 3 to 3.5 trigger installed..

What do y'all think could be the problem?
