Title pretty much says it all and let me preface this with the fact that I have absolutely zero practical application for a .50 nor am I into ultra long range shooting so this is more along the lines of "BIG BOOM COOL" than anything else
Anyhow, I've been tossing around the idea of finding a used Serbu RN-50 in the 18" or 22" flavor (there's bound to be some out there for obvious reasons, IE the exact reason I'm looking at one), slapping a SWFA fixed 10x on top and a folding stock (because covert rifles are cool, .50s are cool, so a covert .50 would be cool^2  ). The question tho would be which adapter would probably hold up? I've seen photos of them with LAW adapters but cannot find any info on anyone actually using one (probably because this is dumb but that's never stopped be before). Or on the other hand would a picatinny style QD mount like SIG has been using be stronger? In practice it'd be similar to how the McMillan CS5/Alias is setup and just detach the stock and clip it to the forend for storage. Thoughts? Criticisms? (Other than OP is an idiot, that's your free square) RN-50 w/LAW pic:  UPDATE 4/18 I've got a Safety Harbor SHTF Single shot upper with the high rail w/ backup irons step headed my way along with everything minus glass and the LAW folder. Ended up being torn between a Noreen and an AR upper and just went for the Safety Harbor simply due to that it was a proper bolt action. Originally I was looking at the aforementioned SWFA SS 10x but was curious on some options in the similar $300-400 price range. Only other requirement is that it is 30mm since I've already picked up the Badger Ord MAX-50 rings (standard .823" height). |

IIWY, I'd find one of those short 50 AR uppers and then use the LAW folder. I think it would be faster to shoot and reload than the Serbu-RN with that threaded cap.

can't help with your exact question, though I support your project 1000%. I have a law folder on a regular AR and honestly I think it's stronger than the buffer tube and lower threads that it attaches to. So if you find something with an AR buffer tube I imagine you'd be good to go

I think it looks perfect with that folding stock on it and if it's as strong as you say it is, keep it or buy one for the RN-50 when you get it. That or have it installed at Serbu when they build it, Mark might be able to get it cheaper.
I don't think that you'll find one that's going to look better than it does. That and it needs to be strong enough so that it doesn't collapse under the recoil of a .50 Cal. I know how it feels when that happens and I can tell you that it sucks! Getting scope eyed from a .50 sucks like nothing else, felt like someone hit me with a pool cue right between the eyes! Anyway, call the shop and talk to Mark and see what he has to say about that stock or if he knows of one that's better. |

Quote HistoryQuoted:
They're definitely super strong, I'm just worried about the hinge pin coming loose or something and a catastrophic failure if I didn't nice. A stock breaking under .50 recoil right in front of your face probably is going to lead to a really bad day. 
Expensive, but cheaper than a facial reconstruction surg bill. |

Nothing wrong with the RN-50, I've shot one and I'm still alive. It's just a cheap .50, the design is sound.
Mark wouldn't let it out of his shop if it wasn't. |

I made a compact 50 bmg with a Noreen ULR shell holder.
Was going to convert it to the 50 spotter cartridge, but never got around to it. Their telescoping stock has some recoil reduction with the springs. The telescoping stock isn't as quick to deploy as the folding stock though, as it uses two clips that fit into holes in the rails. Very secure when pinned into place, but it would be easier to use with some type of retractable pin system. I keep spare clips in the hollow grip compartment. I cut the barrel down to 18" and threaded it to fit the ULR brake. Had them convert the cheek pc to left hand. Have a QD red dot sight and a QD 3x9 compact scope. It fits into an M4 rifle case, but if you pick it up, you know an M4 isn't the case. Even a compact 50 is heavy, but is still fun to shoot. SJC |

I had the same urge, and built a "backpack cannon" using an AR lower with a magpul collapsing stock on the innermost position, and a 12.5" .50 BMG upper from Moriarti Armaments. Long range is one thing, the ability to conceal antimateriel firepower is an entirely different game that I think deserves a lot more attention.

To make that more useful I think that hiding the flash would become important, either via muzzle device and/or atypical powder charges.

I don't think that you could get 260grs of powder in a .50 case. That and the fact that it would probably be a compressed load and seriously hot! Not something that anyone should try, unless pulling the trigger with a string and standing 100 feet away!

Okay then let's back off from within 5gr of a published maximum load and use a different example.
Same 650gr M33 but this time 239.7gr of Vihtavuori 20N29 - that's their published starting load. 12.5" barrel will produce approximately 1,700FPS and 4,150ft.-lbs. Going back to US869 and still with the M33 projectile: 245gr gives approximately 1,840FPS and 4,880ft.-lbs. For a 12.5" barrel there's just no other realistic option and even with such a short barrel it certainly would hold its own against .338LM and similar choices. Mind you I wouldn't want to be anywhere near the muzzle flash when firing. The OP's choice of going with an 18" barrel is extremely sensible. |

I had a heavy bolt lift at 230 grains of US 869 behind 650 grain API's in my AR-50 so I backed off to 225 at it was fine. Published max load data for 50 BMG powders is notoriously high. Your real numbers, from working up to a max load for your rifle, will likely be far less than published max. Be careful....there is a grenade going off in front of your face. |

As was said, don't go by published loads. Some of their starting loads are higher than you want to be!
I always recommend 215grs as a starting load, it's low enough to use for all powders and will send any projo well past 1000 yards. With some pulldown powders, guys have had 215grs be a hot load, that's why you have to start low and work your loads up. You'll also find that you'll get better accuracy using a lower charge. You don't have to max out every load. That and maxing them out will also wear out your brass faster. |

No need to use expensive brass and powder excessively. The only thing I'll disagree on is that I've seen some loads where 215gr is beyond factory maximum. Had more to do with the goofy 800gr+ bullet than the powder so for all normal projectiles your point stands - and saves money. |

Also the ability to fire SLAP or Mk211 has nothing to do with barrel length. If I need to disable a vehicle, I'll take a .50 BMG of any length over a .338 Lapua every time.

If so - please be aware that the muzzle pressure from a 12.5" .50 BMG using ordinary ammunition will be 20,000-30,000PSI. You would need a thick walled can. Yes F1 suppressor-it’s been approved for awhile now The design considerations for a 12.5" barrel will be worth keeping in mind. It's entirely doable of course - but the end result will look different than the same can for a 30"+ barrel! |

Quote HistoryQuoted: They transfer as a "Firearm", 12.5" is not a typo (the rest of the description is just copypasta from Safety Harbor's own page on them, but my understanding is that Moriarti does the chop/thread in-house which is why Safety Harbor doesn't offer that length), and the SHTF-50 mag-fed shown in that clip is the 12.5" model Moriarti sells. I just ordered the single-shot one to help keep weight/bulk down, since the whole project's intent was a backpack-fifty. It will not be the only .50 I end up owning

Quote HistoryQuoted: when you get it, make sure to throw up some pics for us! and a weight for the single shot 12.5" version, since that data isn't available on their site.

More important is that the recoil will be lower due to lower velocity - the perceived recoil will be as well due to the gas working through the brake that much sooner. The balance ought to be further to the rear as well which is always nice. |

Waiting on the pandemic shipping delays is killing me, but when the time comes I'll do some sort of writeup/review thread. I think the other guy is saying the 12.5" upper will only LOSE 1.5lbs or whatever, compared to the 18" one. |

Quote HistoryQuoted: ??? I'm asking him how much the 12.5" upper weighs. Are you saying it should weigh 1.9lbs at most?

Barrel: 12.0 lbs Source |

Jump right into the details without explaining the connection to the subject at hand. Maybe I'm just easily confused. "what does the upper weigh?" "6.5" of the thinnest part of a .50 barrel as used on these uppers doesn't weigh all that much. Figure 1.1lbs to 1.9lbs at most." "wut" Your second way of explaining it made more sense to me. Either way, I'd love to get a confirmation from zombie's scale. |
