I have an LMT MWS. There was a thread on the hide where many pages of posters were getting incredible accuracy. I think I read two pages of posts where people were getting better than 1/2 moa. Mine didn't. As a matter of fact both my Bushmasters and my Colt shoot groups much less than half the size of the LMT MWS.
Should you decide to buy an LMT MWS based on outstanding accuracy claims see the rifle shoot the claimed group before you pay.
The DD doesn't even come close to holding a candle to the LMT. It's absolutely asinine that the DD's price tag is what it is. The LMT utilizes well thought out proprietary parts to become truly a next generation AR where the DD uses proprietary parts to take a step backwards in innovation.
Also--I've had two friends with dd5's that overgas so badly with cans they won't cycle shooting factory match ammo. I don't know if there's a MWS on the planet that's ever malfunctioned. (satire--but you get it)
My LMT MWS with 6.5Creedmoor barrel has taken a bit of load tuning but turned in 4 (5 round) groups of 2-2.5" at 600 yards a couple of weeks ago. It has never had a single malfunction even during load development. Combined with the switch barrel capability, it is a great rifle that I'll never sell. I can hardly believe DD prices have gotten there. I guess it happens when you pick up a government contract. I don't see anything super special about thier rifles but I've never owned one either.
