Featuring an integrated trigger guard for added functionality, and strength and a magwell that has an enlarged bottom flare and inner chamfer for easier clip insertion. The Lug Angle at the shell deflector has been altered to 60.0° for increased effectiveness and the upper receiver has been re-designed to incorporate increased wall thicknesses for added strength. A butt stock attachment feature is fortified for added strength in high power applications. The billet charging handle features a new anti-slip surface for improved grip and the entire piece is Black Hard anodized with a surface hardness of 60 Rockwell.  For more information on this and other Mega Machine Shop products, visit www.megamachineshop.com.
