The RN50 sounds interesting. The price was the real attention getter. Not too many choices out there for a sub-$1k 50 BMG.

if the price is appealing, jump soon. That was the SHOT Show price. It's going up to $1199 shortly.

Am I the only one wondering how a threaded cap can contain a 50 BMG blast?

That threaded cap is very robust. Call Serbu and ask him.

RN-50 is very intriguing, both in design and price. Wondering how easy it will be to remove the spent case. In a perfect scenerio, the shell would just fall out the breech once the cap is unscrewed. Worst case scenario, you have to nudge it out with a cleaning rod. Unless I am missing the extractor system? For the price, very tempting esp if it has a simple extractor of sorts..

I asked the same question just before I ordered one today - if it doesn't come out by grasping and pulling/hand pressure, Mark uses the rim of another cartridge case to pull it out.- hooks the rim of one case (in the barrel) with the rim of the second. I'll probably build a tool to use in "emergencies". BTW, as of this AM, the $875 price is still being honored. |

Looks weird but would like someone to post a video of this in action. Would seem recoil will be strong. Can't beat the cost. May order one if recoil is about the same as my old safety harbors 50BMG. Currently looking for a used single shot and this might fit the bill. |

Videos at: https://www.youtube.com/watch?v=-5T4DwrIB34 https://www.youtube.com/watch?v=vFv7E7QIVWY&feature=youtu.be Safety Harbor has a very good recoil pad on these two buttstocks - http://www.safetyharborfirearms.com/products/accessories - and, of course, the $875 includes Serbu's regular muzzle brake. |

That butt pad safety harbors is using is from zel. I picked up a PRS with that pad for my safety harbor 22 inch when I put one together. It works great. Kept shoulder fatigue down to a minimum. Not cheap though.

And for anyone that says" yea but it half the cost" I say so what. Save a little more and wait if you have to. Even if it never blew up in your face, there is no way after a box of shells that kind of reloading would be any kind of fun. Nope, no thanks I like that there arenore 50's coming but not like this.

Its usually because there is a lot more metal, Parts are larger due to everything being larger, Heck, Ruger could build a .50 BMG on an upscaled American. It's not some magical cartridge that requires Metal forged on Mt.Doom and quenched in unicorn blood. There are plenty of other cartridges out there that develop pressures In excess of the .50 BMG's maximum..If you don't trust a threaded cap to withstand .50 BMG, then how do you trust the barrel of your AR15 not to fall off? Also consider how barretts have a construction similiar to AK/H&K rifles being mostly Stamped and welded Sheet metal, Theres no reason the barrett should cost more than the AR-50, which is a completely machined reciever.. |

They said the pricing would be honored until the 19th. I already got an invoice for one even though I'm not out any money right now. That's not a good sign imo. Since they didn't take any deposits, they can take as long as they want. For $900, I can wait a few months.

I can't really see a difference between a threaded end cap and a threaded shell holder design. Threads are threads.

Even tring to compair it to another breach loader/ shell holder isnt the same. But a shell holder design, like a Watson's for example, is the same concept. A threaded cap mates with a threaded receiver vs a threaded shell holder mates with a threaded receiver. Either way there are just two meshing threads containing the detonation. |

I'm sure the threaded cap is plenty strong, because as the cartridge is fired the case expands and grips the walls of the chamber before reduction of pressure allows it to contract for extraction.
I have not seen one of these yet, and do not know the design details, BUT a properly designed and manufactured cap would have a "shell holder" built into the cap that would extract the case as it was un-screwed. With the cap removed, it would then allow the cartridge rim to be removed from the shell holder. Loading the firearm would be the reverse: Slide live cartridge head into shell holder that is milled into internal face of cap, then load assembly into/onto rifle, and tighten securely. Headspace would not be an issue unless cap has been designed to index to a particular orientation before firing is allowed. Shell holder need not be 270 degrees to work as most other shell holders are designed - a 180 degree holder would be sufficient but more troublesome to load without cartridge becoming dis-connected from cap. Feel free to forward these thoughts to the rifle builder, or have him contact me/ |

Oldman:
Video links: https://www.youtube.com/watch?v=Al9CYrKC3nI https://www.youtube.com/watch?v=-5T4DwrIB34 - at 0:49 The inside of the cap is flat with a provision for firing "pin" in the center (see 2nd video at 0:49, above). There is no shell holder. Extraction, for the most part, has been by simply grasping the case and pulling it out. If it doesn't come easily, use the rim of an empty to catch the rim on the in-rifle case and pull. You'd need to contact Serbu for more details. |
