A little over a month ago, we reported about the release of the HM Defense HM50B bolt action .50BMG rifle, and many of our readers found it suspiciously similar to Bushmaster BA50 and Remington R2Mi. HM Defense brought the HM50B rifle to SHOT Show 2023 (displayed at AmmoInc/Gunbroker booth) and when I visited them, I asked if they can tell me what sets their rifle apart from the other two. Well, they were prepared and provided me an entire list of differences between the three rifles. Long story short, the rifles look similar but they are not the same.

HM Defense have released a new .50BMG bolt action rifle called HM50B. This rifle is marketed as being a higher precision weapon than a typical anti-materiel rifle thanks to features like the free-floated match-grade button-rifled and honed barrel, target trigger and unique lock-up system. The HM50B is also designed to allow working its action while staying on the rifle which is achieved thanks to its ejection port and bolt handle layout – it has a right-side ejection port but a left-side bolt handle attached to the front portion of the bolt.

Ohio-based HM Defense have introduced their Stealth MS5, an integrally suppressed AR-15 with a patented monobloc barrel. Chambered in 5.56×45/.223, the Stealth MS5 weighs in at 7lbs 14oz (without a magazine). The rifle features HM Defense’s ‘Battle Ready’ bolt and HM Defense claims there’s no need for muzzle adaptors and no chance of baffle strikes or suppressor back off. MSRP for the Stealth MS5 is listed as $1,995.

HM Defense has announced that their new HMB AR-15 bolt is now available for purchase. What makes it different is that instead of having a cam pin hole it has a cam pin socket. In other words, the cam pin hole in this bolts is not machined all the way which increases the amount of material in one of the weakest portions of the AR-15 bolt.

HM Defense out of Ohio is announcing the release of their all new HM10 Monobloc rifle dubbed the AVENGER M308 … Yes, in all caps. For dramatic effect.
