M-4 buttstock assembly: This newly designed tele-stock is completely radiused of sharp edges, beefed up around the trigger latch area, and features a "squared hole" design to allow sand, dust and grit to pass through the tube area. The special body style is ribbed for extra strength and durability. The tube was specially designed with a lower lip that acts as a timing lip to insure the buffer retainer is held correctly and the extension is positioned in the correct location, and is dry film lubed for smooth action. Offers six positions of adjustment to fit nearly everyone. Includes a CAR buffer with cylindrical weights and recoil spring.
