Ok you mentioned Hunting, ok you got it that is what i do I am a hunter first, steel stumps tannerite is all second, I bought a DPMS 5 years ago took it out of the box fed it a steady diet of old surplus ammo and oil(mobile one synthetic) and have NEVER had a hickup NONE zero, Nada.... so then with the help of the enabling bastards here on this sight I then started making it my own, I changed the gas block to a A2sight block combo, put a apex Gator grip forend on it changed the stock to a Luth skeloton,and a rock river arms National Match Trigger I like a 2 stage trigger for long range shooting, I shoot Barnes TTSX 168 bullets into one shot holes at 100 years and have killed 4 elk,and 5 deer with it from 40 yards to 346 yards zero issues now my gun weighs 8lbs 8 oz with no ammo in it. I also use a Vortex Diamond back scope 4x14 Mill dot reticle....and I just added a Atlas Bipod but you will get the idea from the photos
