Luth-AR AR-10 308 Win 20rd Steel Magazine

Luth-AR builds this magazine on the DPMS pattern, which covers most of the 308 AR rifles in circulation. It feeds 243 Winchester, 260 Remington and 308 Winchester out of the same body, since those cartridges share a case head and overall length. Steel construction takes the load of a 20 round stack without flexing at the feed lips the way thin bodies can.

The finish is manganese phosphate, a matte gray coating that holds a light film of oil and keeps rust off a magazine living in a range bag. A black polymer follower runs the stack, and the steel floor plate slides off so the body can be emptied and wiped out after a dusty day at the range.
