Description
Picture this: you’re at the range, and the standard calibers just aren’t scratching the itch. You want to feel the concussive thump, see the earth move downrange, and command a round that defines power. That’s the realm of the .50 BMG—a caliber for making statements, not just holes. But entry has traditionally meant a massive financial and logistical commitment. Here’s the thing—the Serbu RN-50 Single Shot 50 BMG Rifle 29.5″ Barrel, No Butt Stock (Uses AR-15 Stock) changes that equation entirely. It’s a minimalist, no-frills platform that delivers the .50 BMG experience at an accessible price point, demanding only your respect for its formidable power.
Answer Capsule: The Serbu RN-50 is a single-shot, break-action rifle chambered in .50 BMG. It features a 29.5-inch barrel and is supplied without a buttstock, designed to accept a standard AR-15 buffer tube and stock for a customizable fit. This configuration provides an economical and straightforward entry into the world of large-caliber precision and long-range impact shooting.
Key Features & Practical Design
This isn’t a rifle burdened by complexity. The RN-50’s genius is in its simplicity. The break-action design is robust and intuitive—load one massive round, close the action, and you’re ready. The 29.5-inch barrel provides the necessary length for the .50 BMG cartridge to achieve its formidable velocity, translating to staggering downrange energy. Weighing in at approximately 22 lbs without a stock, it’s a serious piece of kit, but the heft helps manage the legendary recoil. The absence of a proprietary stock is a feature, not an omission. By utilizing a standard AR-15 buffer tube, you can attach any compatible stock you already own and trust, from a Magpul CTR to a B5 Systems Bravo, creating a personalized length of pull. This mil-spec compatibility means it’s drop-in ready with parts you likely have on hand.
When it comes to handling a .50 BMG, safety and control are paramount. The RN-50 incorporates a manual cross-bolt safety for positive peace of mind. Its single-shot nature forces a deliberate pace—this is a rifle for methodical shooters, not volume fire. Each shot is an event. The price of admission for this kind of power is a compelling $1127.99, a figure that redefines what’s possible for enthusiasts wanting to step up to the big bore league. This firearm is available at firearms-missouri.com for Missouri residents and nationwide, following all applicable FFL transfer requirements for firearm purchases.

Pros & Cons
Pros: Unmatched value for entering the .50 BMG arena. Simple, reliable break-action mechanism with no complex gas system or magazine to fuss with. Highly customizable shoulder interface using ubiquitous AR-15 stocks. The 29.5″ barrel ensures proper ballistic performance. Builds fundamental marksmanship discipline through its single-shot design.
Cons: It is a single-shot rifle—follow-up shots are not an option. The weight, while manageable, is significant for a reason. You will need to source and attach your own AR-15 stock and buffer tube assembly. Ammunition cost per round is high, as expected for the caliber.

It is emphatically not a tactical or defensive firearm; it’s a range instrument, a ballistic demonstrator, and a gateway to understanding one of the most iconic cartridges in existence. You must have the space and a suitable range to safely unleash its potential.
Frequently Asked Questions
Q: What exactly do I need to complete this rifle?

Q: How severe is the recoil?

Q: Can I use any .50 BMG ammunition?
A: It is designed for standard .50 BMG ammunition. Always consult your manual, but it handles both mil-spec and commercial loads. As always, start with factory ammunition from reputable manufacturers to ensure safe operation.
