Wow, that really suprises me that this is a common problem!!! Come on Bushmaster! I'm somewhat comforted I'm not the only one, but also sorry that others suffered the same misfortune. I just waited 2 months to get this beautful work of art, and now I have to send it away for 3 weeks :( . Do they have to test fire it? Should I keep my bolt and goodies with the upper? To all of you guys that have sent your AR's into Bushmaster for work: were you happy with their service? Any new scuffs or dings?? quote]
Bushmaster has had some trouble with this issue. I think it's gotten much better lately, since we don't see as many posts about it.
The service was outstanding. I sent the complete upper. I assume they re-test fire the gun, so they would need the b/c assembly.
I sent mine in on a Thursday, got it back the following Tuesday.
