Milsport Arms recently released their new skeletonized forged 7075-T6 AR-15 80% Lower Receiver. It has cutouts on both the front and sides of the magwell with pockets milled out of both sides of the receiver. I couldn’t find an exact weight on the new MilSport Arms skeletonized lower but I’m guessing they shaved off at least a few ounces compared to a standard AR lower. Since these are 80% lowers that you’ll be completing yourself no FFL is required to purchase them. They currently go for $69.95 over at Rainierarms.com.

These 80% AR-15 Lower receivers are forged in the US and are machined to mil-spec tolerances. Build your next custom rifle using a quality machined Milsport lower that are proven and tested.
