I feel like the complete upper I purchased from palmetto was a solid choice it’s the fn barrel and the geissele rail I figured spend a few more bucks the fn barrels are top notch I use a 16 inch for my 600 yard range at my club
I’m just not impressed with the bolt, I shouldn’t of bought it. Anyway when I have time this week I’m going to do a full inspection I will let everyone know how it goes. Like I said it just seems there is a lot of friction there with this bolt the others I tried felt smooth.
The upper receiver is solid with all other bcg just seems like this fail zero carrier is out of spec or poorly built the pistol I built is not my first so I’m going to take it apart and see what’s going on but this bolt is going in pile of parts and already ordered a bcm bolt
