Whether you’re on the hunt or engaging a long-range target, you need a heavy-duty caliber that delivers power and precision, and When Every Round Counts™, you can trust the Hexmag AR-10/.308 SR-25 magazine by SENTRY. Engineered from SENTRY’s PolyHex2™ Advanced Composite and featuring SENTRY’s signature HEXTURE™ pattern, these magazines are designed to handle the demands of 7.62x51mm (.308) Winchester calibers. All limited capacity magazines feature the True Riser system pioneered by SENTRY. You get a standard size magazine body that has the internals of a shorter magazine so it will look natural in your rifle and fit in all of your gear appropriately. 

*** PLEASE NOTE*** State / County / City laws and regulations regarding limited round capacity magazines continue to be implemented and/or changed on an ongoing basis. Because each of these State / County / City capacity laws can be written or interpreted differently, Hexmag has elected to permanently affix the baseplate on all limited capacity magazines. This includes the 10 and 15 round AR15 and 10 round SR25 magazines. The baseplate will be secured to the HexID restricting access to modifications and takedown. If you wish to use a custom color HexID on your limited capacity magazine, please make your color selections upon ordering.

10rd Hex Mag
Written by Morgan on 21st Apr 2020

I purchased the 10 rd hex mag in black about a week ago maybe a week and a half and my order was shipped out on Monday (I ordered on Saturday night at 11:45pm pst) and I received the magazine on that Friday. I’m more than happy with the way it looks on the .308 build I’m doing and can’t wait to shoot with it. I loved the way it looked so much that I ended up buying a Hex Grip the other day. Definitely going to buy my magazines and grips from Sentry/Hexmag again. I would definitely recommend for any AR that you want to look better for not a lot of money. I think it’s like $50 or $55 for a mag and a grip. I also love that the magazines are the same price for a 10rd and for a 20rd and that price is still cheaper than a lot of other places. To sum it up, Sentry’s Hex products are the shit and you need some in your life! Thanks again for the quick shipping even while the world is going crazy from this corona virus

AR10 10rd Mag
Written by San on 31st Mar 2020

10 round mag has been riveted to the bottom preventing the mag from dissembling in case of a malfunction. I would not recommend the 10rd mag to anyone who lives in one of the restricted state. There may be no hope to clear malfunctions for those in restricted states using the 10rd mag.

I got a 20 rounder and a 10 rounder...They are the same size(and it appears the 5 also). Maybe there is a reason, but I was hoping the 10 would be smaller. Although, these mags are lovely and I'm sure work just fine (haven't used it yet.)

Just received yesterday, tried them today' just like my 5.56 Hexmags function flawlessly. I live in CA and can only have 10 rounds the Hexmag design allows me to fully strip them for cleaning unlike other magazines alterations that make them unable to be disassembled! Getting ready to build a 7mm-08 upper I will be glad when the HexID Color system is available for these mags.
