So I've had an ar15 and now i'm looking to buy a .22lr upper. I have a spikes lower with/RRA single stage trigger and i plan on getting LPK from palmentto state armory. I'm looking to buy a CMMG m4LE upper with the SS bolt and forward assist upgrade maybe the anodized upgrad and collar upgrade as well. I think i may go with the BHAO upgrade but not sure if i want to spend the extra since it' only works with CMMG mags (I can always added it later). I hear some good things about CMMG but any ideas what other .22LR uppers considered good? Where does CMMG ranks in at with the other .22LR uppers? For the people that has a CMMG, how do you guys like it? Any issues with any particular type/brand ammo? I've read the someone had issues with CCi stingers with their cmmg. Thanks.
