I’m comfortable saying that Magpul is instrumental to why the industry adopted the KAC SR25 magazine pattern for the current crop of magazines. Magpul was also the first good polymer magazine for the platform. Named the PMAG LR/SR (but also referred to on Magpul’s website as SR25/ M110), it’s available in the standard 20-round capacity, low-profile 10-rounder and the 25-round extended capacity with additional curve to allow reliable feed of the M118LR and other match-grade 7.62x51mm/.308 Win. rounds with longer projectile.
Much like Magpul’s popular AR-15 PMAGs, the LR/SR is constructed entirely from polymer, with the exception of the stainless steel follower spring. It is very affordable, with a street price of around $20. However, there are concerns about the longevity of the polymer feed lips (especially in subzero temperatures), as well as reports of pitting on the inside front surface from bullet tips after being in use for a while. The Magpul PMAG SR/LR functioned flawlessly in all three of my testing ARs.
The PMAG 10- and 20-round magazines in front of a test rifle from Aero Precision. It’s also available in five-round. I
The Magpul PMAG LR/SR uses a curved magazine design, which allows for improved feed reliability and longer cartridge overall length.
