You clearly don't know WTF your talking about! Cmt makes and sells stg and rra the same parts. Rra has a great fit and finish due to the maching of the parts from cmt. Stags are priced a little cheaper. Both are good guns. Cheap, that's your two dpms ar's my friend. This coming from a guy whonhas not one, but two dpms firearms. Sell them both and buy a rra or spikes. Let me guess spikes sucks as well? If you want the best go cd or lmt for the monies. For your average civillian use, go rra or spikes
