I'v done some research not too extensive, and if I had to choose 1 AR-15 and 1 AK-47, I would choose a Colt LE6940P with the articulating link gas piston system, and an Armament SA-M7R My mind would already be made up on ALP system vs direct impingement for the AR. Choosing between those two rifles would be quite difficult, but honestly I think I would go with the Colt 940P. ARs are known to be more accurate at longer ranges (500 yds+) and the lighter 5.56 round is favorable in terms of ranged ballistics. Losing the long tested reliability of an AK platform would be a really tough thing to do, but the articulating link piston system of the 940P I think would suffice as well as an AKs gas piston system. Granted this is all hypothetical, but the Armament AK is about 900 dollars cheaper than the Colt 940P, so if I didn't have the funds, I would still have an awesome rifle in the Armament. Does anyone have experience with either of these rifles, and am I sound in my judgements and thoughts?
