Re: Suggestions for an AR-10/SR-25 DMR build or rifle
Mega's Ma-Ten billet upper and lower sets are great in terms of quality and parts compatibility. They accept all AR-15 lower parts, except for a .308 bolt catch. You can utilize either DPMS or Armalite pattern barrels and bolts, as they will accept both. You MUST stick to the same pattern when purchasing a barrel an bolt. The same goes for when choosing a rail for the Ma-Ten platform. Ensure you get the proper barrel nut. Its very simple.
