This is the Lancer L7AWM 25 round steel feed lip magazine for .308 and 7.62mm AR rifles.
The magazine features a generous COL of 2.85" making it an ideal choice for precision long range reloading.
Lancer Systems developed their L7 Advanced Warfighter Magazine (L7AWM) to have the weight benefits of a polymer magazine with the durability of steel, by having one piece wrap steel feed lips and contact points formed around a tough polymer body.
They are very durable and ideal for use in challenging weather conditions, including a switchable drain hole.
Compatible with common AR10, LR/SR and STANAG formats including the Ruger Precision Rifle, LM 308 and others.
Won't fit: Armalite AR-10B, Springfield M1A, M14. FN SCAR 17S, PTR-91, HK417, FN FAL, HK 91, HK G3.
