Magpul PMAG 20-Round LR/SR GEN M3 .308 Magazine


The Magpul 7.62x51 NATO (.308 Winchester) PMAG 20 LR/SR GEN M3 is a lightweight, cost effective, high reliability magazine for SR25/M110 pattern rifles featuring true 20-round capacity, constant-curve body, anti-tilt follower, and snap on Impact/Dust Cover. Designed specifically for military-issue MK11/M110 rifles and mil-spec ammunition (including M118LR), the PMAG 20LR/SR is less than half the weight of standard issue steel magazines and maintains a service life round count approximately equal to the rifle barrel itself.


  • Optimized for use with 7.62x51 NATO (.308 Winchester) ammunition with an overall cartridge length less than 2.820", including M118LR

  • Additional commercial rifle compatibility includes the new Armalite AR-10A, Bushmaster .308 ORC, Colt LE901-16S, CORE Rifle Systems CORE30, DPMS, LR308, JP Enterprises LRP-07, KAC SR25, LaRue OBR, Les Baer .308, LMT .308 MWS, LWRCI REPR, Mega Arms MATEN, POF P-308, Remington R-25, Ruger SR-762, S&W M&P10, SIG716, and others

  • NOTE: NOT compatible with Armalite AR-10B, Noveske N6, Springfield Armory M1A, Rock River Arms LAR8, FN SCAR 17S, PTR-91, HK417 or any other rifles that utilize M14, FN FAL, or HK 91/G3 patterned magazines

  • Next-generation impact and crush resistant polymer construction

  • Constant-curve internal geometry for smooth feeding

  • Anti-tilt, self-lubricating follower for increased reliability

  • High-quality stainless steel spring for corrosion resistance

  • Ribbed gripping surface and new aggressive front and rear texture for positive magazine handling

  • Paint pen dot matrix panels on the bottom of the body to allow for identification marking

  • Flared floorplate aids magazine handling and disassembly yet is slim enough for use with many pouches

  • Multi-use Impact/Dust Cover minimizes debris intrusion and protects cartridges from potential damage during storage and transit

Reviewer: Douglas from Wichita, KS United States  
The prices I’ve seen on your site have been reasonable for current market conditions. Delivery was an slow, but it was over the holidays, so only half off on that.

5 of 5 Great Service January 2, 2021
Reviewer: Thomas Miller from Malta, MT United States  
Ordered the items and was promptly given a tracking number. Package arrived much later than expected since the shipping label was 3 day priority, but no fault of arms unlimited. Packaging was great and product is top notch
