Frequently Asked Questions
Will this magazine fit my ArmaLite AR-10 rifle?
No — this ProMag magazine is specifically designed for rifles using the LR-308 (DPMS) or SR-25 magazine pattern. It is not compatible with rifles using the ArmaLite AR-10 magazine pattern. Before purchasing, confirm which magazine interface your rifle uses. Common LR-308/DPMS-compatible brands include DPMS, Palmetto State Armory Gen 2, Aero Precision M5, and many others. SR-25-compatible rifles include those from Knights Armament and several Sig Sauer models.
Is this magazine legal to purchase and use in California?
Yes — this magazine ships with a blocked, California-compliant 10-round capacity, making it legal for purchase and use in California under the state's standard-capacity magazine restrictions. The magazine body is the full 40-round size for ergonomic handling, but it is permanently configured to hold no more than 10 rounds as required by California law.
How reliable is the ProMag polymer magazine compared to steel alternatives?
ProMag's Zytel-based polymer magazines are engineered for consistent performance, featuring heat-treated chrome silicon wire springs and precision injection-molded followers that reduce friction and promote reliable feeding. While personal preferences vary, ProMag backs their magazines with a lifetime guarantee against manufacturing defects, reflecting confidence in their build quality. For best results, perform a function check with your specific rifle before field or defensive use.
