Forgive me brothers for I have sinned
dispite several warnings on this forum,against buying a Model 1 sales upper in a moment of desperaton when price's were insane and uppers hard to come buy.
I did the dirty deed, I bought one. At first i had no problems with it.After a few hundred rounds I'm getting case head seperations on every shot,At first i thought it was the ammo but i switched over to a PKFirearms AR it fired every round with no problems. I'm thinking I have a long headspace This is the heavy barrel 1/8 twist ershaw stainless barrel. I guess I'll be sending it back to Model 1.
