Description
The Magpul PMAG 10 LR/SR GEN M3 is a compact 10-round magazine for 7.62×51 NATO / .308 Winchester SR25, M110 and AR10-pattern rifles — a genuine 10-round body rather than a blocked 20. The impact- and crush-resistant polymer body, stainless-steel spring and self-lubricating anti-tilt follower give the same feeding reliability as the full-size LR/SR PMAGs, and the 4.1 in overall length sits neatly for prone or bench shooting. Magpul lists it as optimised for M118LR / Mk316-type match ammunition up to 2.830 in overall length, and compatible with the Armalite AR-10A, KAC SR25, LaRue OBR, JP LRP-07, Colt LE901 and many other SR25/M110-pattern rifles.
