Did a search for this, couldn't find anything - hope someone has some insight.

I have two ARs - a CavArms carbine with a stock trigger, and a Bushy / RRA middy with a Bushy DCM 2-stage trigger. The CavArms never has a problem shooting anything I feed it, and the Bushy never has a problem with civvy loads, but as soon as I give it some South African / SS109 / M855 / mil surp it starts to misfire. Not every time, not even every other time. Sometimes it'll be four in a row, sometimes once in a mag. Sometimes I can reload the round and it'll fire, sometimes not. The round isn't bad 'cause like I said sometimes it'll fire if I load it again, and then if I put it in the CavArms it'll always fire.

So my question is, is it just my trigger? Should I avoid the mil surp stuff in this rifle or can this problem be remedied? I'm not sure if this trigger is adjustable; Bushy website doesn't really specify, and I'm not sure what to look for.

I'm not as impressed with the stock 2 stage in my Bush-hamster Varminter as I am with the Bill Springfield 4# in my Spike's lower.

Just my opinion.

Is the hammer spring installed correctly? Can you post a pic of the inside of your lower?

Bushy put the lower together, so I hope it's in there right! I'll post some pics later. This is actually the lower off of a Bushy Varminter, and if I had the $$ I'd buy a new trigger, but right now I need to fix it on the cheap. If I need a new hammer spring, should I go Wolff? Any better options?

Isn't the heavier spring that S&W includes in the AR-5.45 kit a Wolff spring? I'd assume that it might be a reasonable place to start.
