Mine barely comes out....No one here in CA wants to touch it as they have no experience with MP10....I have also been told by SW that you cannot use a different bolt as it is a different size. Need real help here

My current understanding is that to use a DPMS pattern barrel, you would need to also use a DPMS bolt carrier and bolt assembly. You would also need to check headspacing on the components as the FP protrusion could cause light strikes as well on a loose assembly. I am not sure if DPMS uses a FP spring either, and depending upon ammo, this combo could cause issues, as the original gun was set up for commercial hunting ammo with potentially lighter primers than a mil spec projectile.
