Serbu Firearms is best known for their SUPER-SHORTY shotgun, which I reviewed here a few months ago. That certainly isn’t their only product, though, as Mark and the gang have been manufacturing a semi-auto .50 cal and an affordable ($1,900) bolt-action .50 cal in addition to a buffer tube-less AR-15 for years. In collaboration with an interesting YouTube personality, Serbu is now offering a .50 BMG (or .50 DTC) rifle at an introductory price of only $875. Which is pretty crazy. But, yes, there’s a bit of a catch . . .
You see, that YouTuber is Royal Nonesuch. His ~131,000 subscribers come to see his homemade firearms, which are often hardware store creations. As in, plumbing parts and galvanized pipe. Serbu borrowed him to aid in their quest of creating the simplest, least expensive .50 cal rifle possible. The result is the break-action, single-shot RN-50.
Of course, it isn’t a hardware store special and Serbu is machining it out of actual ordnance steel and such. But it is a single-shot in the style of Mr. Royal Nonesuch — which is much like various other breech loaders — in that the rear of the breech must be opened up in order to insert a round into the chamber or to remove a spent case. On the RN-50, it’s a thread-on breech cap that secures the round inside of the chamber and houses the firing pin.
So it won’t win any speed shooting contests, but it will help one’s .50 BMG ammo budget last a little longer. It’s also a simple, lightweight solution. In fact, with 29.5″ barrel the whole shebang is only 17 lbs. Okay, that isn’t light, but it’s light for a .50.
The RN-50 accepts AR-15 grips and buttstocks, and has rails for mounting an optic and a bipod. Apparently it’s an accurate rifle, too, which I may just find out for myself if Serbu ends up loaning me one. As it states in the flyer below, $875 is an introductory price. I’m not sure how long that’ll be good for, but MSRP once these go into full-on production still won’t hit four digits.
Easy barrel change for different calibers, indeed.
