Re: DPMS SASS
I second the new trigger recommendation.
I just put one of the Geissele National Match trigger on mine and absolutely love it. VERY adjustable, but I left the 1st stage alone for fear that I might booger it up somehow. The JP trigger on mine was kind of "catchy" for lack of a better term. Granted, it was way better than a normal AR trigger, but when trying to shoot nice tight groups, it could be a pain in the rear. I bought into the Geissele hype and I am sure glad I did.
The only other thing I want to replace on my SASS is the charging handle. Because of how my scope is mounted, it can be a pain in the butt to get to the charging handle. I'm thinking of getting one of those larger BCM handles.
The only other negative I'd like to work out with the gun is to figure out how to make it not chew the brass up so bad. I know semis are hard on brass, but this thing sure puts some marks on them.
Good luck with the gun. I'm very happy with mine and it consistently shoots very well.
