OK, I confess that I have been bitten by the AR build bug and want to build a dedicated long range target and varmint rifle in 223/5.56. I already have a new Ruger lower and an upper that is a snug fit bought from a local gun store. My plan is a 20" heavy profile barrel, fixed buttstock, free floated handguard. But, looking at match grade triggers has filled my head with confusion. I thought about Timmey triggers first, then CMC (Chip McCormic), and now I see that Brownells has Geissele triggers for a decent price. Does anyone here have experience with any of the above manufactures? Looking for something in the 4 to 4.5# range as I may want to compete in matches at some point. Thanks for looking.
