Quick shipping, excellent packing. Each mag was in its own clear plastic bag, with all 10 in being in one larger bag. Rounds loaded real easy, mags pop in and out of rifle real easy. Now have 300 rounds of 5. 56 ready to go, Baby! Can't speak to durability or longevity, only just now got them. However, for an out-the-door price of $7. xx including tax, shipping, etc. I won't complain if one of them empties once and then breaks. Or if I step on one and it breaks. Or if I lose one out of an airplane and it breaks. Or if I accidentally mistake it for a frozen burrito, microwave it and it breaks. I'd still have six left.On KCI USA AR-15 Polymer Magazine - 30rd (10 Pack)SSTEPHAN G.Verified Buyer5.0 star rating08/14/25Exactly as advertisedReview by STEPHAN G. on 14 Aug 2025 review stating Exactly as advertisedEverything fit as it should.

My off hand, great, I really like the thumb rest. My touch point for my trigger finger is jacked up though. The gas pedal gets in the way transitioning from the slide to trigger housing. It’s like a hitting a speed bump from out of nowhere. If it keeps going like this I’m going to dremel it off. Other than that it’s a solid grip module.On Sharps Bros Sig Sauer P365 X Macro Gen 2 Manual Safety Grip Module - Black Anodize w/ Brazilian CherryRRobert C.Verified Buyer5.0 star rating08/13/25Great magazines for the priceReview by Robert C. on 13 Aug 2025 review stating Great magazines for the priceGreat magazines for the priceOn KCI USA AR-15 Polymer Magazine - 30rd (10 Pack)$400.00Out of stock -
