LMT CQB MRP Defender Model 16 Colt 6940 Daniel Defense M4 Carbine I am in the market for AR and have narrowed it down to these three. I actually had it down to the LMT and Colt but just found a deal on the DDM4 that I might not be able to give up ($1295). However, I am not too fond of the extended rail of the DDM4. I've looked at the "chart" and I think anyone of these will be a great rifle, but wanted to get some opinions from the crowd, first hand experience? Any advice for this AR newb?
