The DPMS LR308 upper is a complete flat-top drop-in unit complete with bolt and bolt carrier, charging handle, free-float handguard, gas block and barrel. Chambered for .308 (7.62X51 NATO) this 308 upper enables you to switch your rifle from a carbine to a long range varminter in a few minutes. You can use this AR 308 upper to build a whole new gun tailored to your needs. The receiver on the CM and SS models does away with forward assist, shell deflector and ejection port cover to give a very smooth, sleek appearance like the original AR-10. The AP4 has an A4 style receiver with all of the above. The 6066 T-6 aluminum receiver is thick-walled for stability and both hard anodized to Mil-Spec and coated with hard, black teflon to resist abrasion. The .308 AR upper is mated to a 1:10 twist barrel to stabilize long, heavy bullets. The Hi-rider reciever includes a raised Mil-Std 1913 Picatinny rail for ease of scope mounting without having to employ a riser mount. A lightweight aluminium gas block is employed and has sufficient mass to absorb heat during sustained firing. It has a Picatinny rail for foresight mounting. The free-float fore-end on the DPMS LR308 is aluminium with sufficient clearance to prevent it heating up excessively in sustained fire. The fore end includes both a swivel stud and a QD sling swivel. The following models are available:
CM 18″ barrel of 4140 chrome-molycarbon steel alloy and 7¼” carbine-length forend.
SS 24″ bull barrel of 416 stainless steel with 12″ rifle-length forend.
AP4 Carbine has A3-style Lo-Rider receiver with forward assist and ejection port cover. 16″ USGI-style, light contour barrel of 4140 chrome-moly, with M203 mount cutout, 7¼” forend, and A2-type gas block/front sight tower with bayonet lug and sling swivel. Includes Panther flash suppressor with gas-dispersing helical ports and aggressive, serrated CQB tip.
These units are only intended to fit DPMS lower receivers.
