Description
There is nothing quite like sending a .50 BMG downrange, and the HM Defense HM50 B1 makes the experience feel a lot more refined than the typical big bore bruiser. HM Defense builds this rifle around a 26.25 inch, 8-groove match grade barrel with a threaded muzzle, so you get real precision potential in a package that is a bit handier to move around than the longer barreled rifles in this class. The receiver is machined aluminum wearing a tough black hardcoat anodized finish, topped with a Picatinny rail that gives you plenty of room for the kind of glass a rifle like this deserves.
Built for Steady Work at Serious Distance
Up front, the M-LOK handguard keeps things trim while still giving you attachment points where you want them, and the Picatinny rail forend includes an integrally machined bipod mount so your support is anchored to solid metal rather than a bolted-on afterthought. That matters on a .50, where a wobbly bipod connection can eat into your consistency shot to shot. Behind the action, the HM Target trigger breaks clean, which does a lot of favors for your groups when you are stretching things way out there.
Fit the HM50 B1 to You, Not the Other Way Around
The CNC machined stock adjusts for both cheekpiece height and length of pull, so you can build a repeatable position behind the scope whether you are prone off a bipod or set up on a bench. The ERGO Tactical Super Ambi grip rounds out the control setup and feels familiar if you have spent time behind AR pattern rifles. Feeding comes from an included 10-round military grade steel magazine, which is a nice step up from the single shot .50s that make you break position after every round. For long range enthusiasts ready to move into the .50 BMG world, the HM50 B1 is a well thought out way to do it.

Frequently Asked Questions
Is the HM Defense HM50 B1 bolt action or semi-auto?
The HM50 B1 is a bolt action rifle chambered in .50 BMG. HM Defense builds its 50 caliber line on a manually operated bolt platform, which keeps the design simpler and helps deliver the consistency you want for precision work at long range.
Does the HM50 B1 come with a magazine?
Yes, it ships with one 10-round military grade steel magazine. That detachable box mag is a big practical advantage over the single shot .50 BMG rifles out there, since you can run longer strings without breaking your position to reload after every shot.
Can I mount a muzzle brake or suppressor on the HM50 B1?
The 26.25 inch match grade barrel comes threaded from the factory, so you can attach a muzzle device of your choice. On a .50 BMG, a quality brake makes a huge difference in felt recoil and muzzle movement, so most owners will want one installed before spending a full day at the range.
How adjustable is the stock on the HM50 B1?
The CNC machined stock adjusts for both cheekpiece height and length of pull. That lets you set a consistent cheek weld behind large precision optics and dial the fit to your build and shooting position, whether you are prone off the bipod mount or working from a bench.
