Description
There are big rifles, and then there is the HM50B2 Gen 2 from Luxus Arms and HM Defense. Chambered in .50 BMG with a 10+1 capacity and a semi-auto action, this is the kind of rifle that turns a range day into an event. The Gen 2 is the evolution of the original HM50B, with the upper receiver, lower receiver, and rail redesigned for a cleaner, more modern look while shaving weight where it counts. The Flat Dark Earth finish gives it a purposeful look that stands out from the sea of black rifles on the line.
Built Around a 29.25 Inch Match Barrel
The heart of the HM50B2 Gen 2 is its 29.25 inch button-rifled, match-grade barrel with a 1:15 twist, threaded 1-14 at the muzzle so you can run a brake or other muzzle device without any gunsmith work. The aluminum receiver keeps the overall package manageable, and the 14 inch Picatinny rail up top gives you all the real estate you need for a long-range optic with proper eye relief. An HM Target trigger rounds things out with a clean, crisp break that lets you get the most out of this cartridge at distance.
An Adjustable Stock That Fits You, Not the Other Way Around
The HM Precision stock is CNC-machined aluminum, joined to the lower receiver with a steel through-bolted mounting system, so there is zero wiggle back there. Comb height, length of pull, and the butt pad all adjust to fit your build and your shooting position, and the flat-bottomed design rides a rear bag nicely. A removable 1913 rail section underneath gives you a secure spot to mount the included monopod. Up front, the ERGO Tactical Super Ambi grip works comfortably from either side.
What Comes With the HM50B2 Gen 2
Out of the box you get the rifle, one 10-round magazine, the removable monopod mount, and a hard case with laser-cut foam that keeps everything protected on the way to the range. At 29.75 pounds it is a dedicated precision rig, built to soak up recoil and print tight groups way out past where most rifles give up.

Frequently Asked Questions
Is the HM50B2 Gen 2 semi-automatic or bolt action?
This model is a semi-automatic .50 BMG with a 10+1 capacity. That sets it apart from most .50 caliber rifles on the market, which are single shots or bolt guns. The semi-auto action also helps tame felt recoil compared to a fixed-breech design.
What changed between the original HM50B and the HM50B2 Gen 2?
HM Defense redesigned the upper receiver, lower receiver, and rail with a more modern profile, lightening and strengthening the areas that matter most in hard use. The Gen 2 also uses the HM Precision adjustable stock, which is steel through-bolted to the lower receiver and offers an adjustable comb, length of pull, and butt pad.
Can I mount a muzzle brake or suppressor on the HM50B2 Gen 2?
Yes. The 29.25 inch match-grade barrel comes threaded with a 1-14 pitch, which is the common standard for .50 BMG muzzle devices. With a cartridge this size, a quality brake makes a real difference in felt recoil, so most owners run one.
How heavy is this rifle and does it come with a case?
The HM50B2 Gen 2 weighs 29.75 pounds with an overall length of 56.75 inches, so it is a dedicated bench and prone rifle rather than something you carry all day. It ships in a hard case with laser-cut foam, along with one 10-round magazine and a removable monopod mount.
