The receiver material or how the upper and lower fit together has absolutely no bearing on accuracy.
Are the bolt and barrel proprietary? If not, change them out - and not with something else from Bushmaster.

The bolt has more rounded lugs than a standard AR. So the bolt and barrel would have to be changed together. I'm sure the carbon handguard is unique so that too would have to go.
Does anyone know why I'm having such accuracy issues? The parts appear to have little to no wear and are clean, good condition etc. Was the stainless fluted barrel of poor quality to begin with? Maybe headspace is an issue to be checked.
Had it to the smith to tune the trigger, but didn't have him check anything else.
How many rounds do you have through the weapon?
Can you even put a standard barrel assembly on the weapon?
I dropped a BCM 16" midlength on my Carbon 15 lower. So far it's a tack driver.
I think tgace is the guy I need to talk with.
I assume you changed the bolt and the barrel? Handguard?
Were you having the same issues I am?
I haven't put that many rounds thru the rifle, but I bought it used.
Upper receiver material could impact accuracy.Quote:

This is a photo of a rifle like mine.
Well, I have a BM M4 flattop Carbon 15, not the older Prof Ord model so I don't know if it will work for you. I purchased a BCM upper with a BCM BCG and dropped it on.Quote:

If the receiver flexes, accuracy could be affected. I don't know if this is the case with the rifle in question, but it is possible.Quote:
