I'd like an M4 style with the A4 type flat top receiver. I held a Bushmaster M4 tonight and it felt just right. I know RRA gives a guarentee of accuracy on their website, but I don't know about bushmaster. Bushmaster has soo many different types of muzzle breaks it makes my head spin trying to pick one out. I held one tonight that was $999. It's awfully tempting, but I want to make darn sure that I'll be getting 1" MOA at 100 or less for that kind of money, semi-auto or not. Anyone here have any muzzle break preferences other than cosmetic ones? Also is a bushmaster M4 easily capable of 1" accuracy at 100 yards? I'm sure it won't with the wolf cheapo ammo, but I would hope for sub, MOA with my handloads. Is that reasonable and realistic?
