Re: Looking for a AR... what make?
I'm a big fan of LMT and Larue. I have 2x LMTs (1 DI, 1 piston) and a Larue SPR. Having said that, any of the brands listed above will work fine for plinking. Some other brands that were not listed but have decent reputations in the budget range are: Stag, YHM and Double Star.
However, if its a duty weapon - a few of those on the list start falling off the plate for consideration. From doing a LOT of research when shopping for mine, the consensus (such as it is) is Olympic Arms and DPMS would probably be the 1st to go.
I'm no AR expert (not even close), so take this with a grain of salt: I've generally classified AR brands into 3 tiers. Top tier ARs would generally be Colt, Noveske, LWRC, LMT, Larue, etc. Middle tier (where the majority live) would be: RRA, Bushmaster, Double Star, Stag, BCM, S&W, Ruger, POF, CMMG, Spikes, Daniel Defense, etc. Bottom tier usually include DPMS, Armalite and Olympic Arms.
