dont know about that. I had a sprotical and it was a great little ar. I liked it because it was about a lb lighter then any of my others. Sure it was missing the forward assist which shouldnt be on any ar!! Its also missing a dust cover which i do like but sure isnt nessisary and it lacks the chrome lined barrrel which is good and bad. Good because the non chrome barrels usually shoot better bad because if your going to run one like a machinegun the chrome bore will hold up a bit longer. Other then that theres not spit differnce between a dpms and a bushmaster. Both are non milspec ars with cheap bolt carrier groups.
