The groups were about 2.5.@ 100 I am looking to bring that down to MOA if possible. Might be asking too much. I used Winchester 55 gr. SP ammo. Thinking of putting a RR 2 stage NM trigger. Didn't know if the bolt carrier had much to do with accuracy. Also shooting 223 in the 5.56 chamber?
Bringing a 2.5 moa rifle down to 1 moa, may be a challenge, even if you are only shooting 3 shot groups. Delton is more known as a budget rifle, not really accuracy. Id probably trust a barrel from a known maker, more than the delton barrel. Like others have said, accuracy starts with a good barrel.
