Need So. Cal. gunsmith for brake install on a carbon wrapped barrel-know anyone>

[Deleted member 137765]

I have an 18" fluted carbon-wrapped barrel from BSF that I wanna put a muzzle brake on but want someone who has done this before. BSF is quite specific about the manner in which this is done (as shown at https://94fbfb53-6b6e-4f62-acab-29f...d/5e8dd2_9d1a7e4d524d4e558410ebdc31139632.pdf) but I don't want my rifle to be part of a gunsmith's learning curve.

Need someone with experience. Know anybody? Putting it on this rifle.

Is AR15barrels still down there?

 

[dtma42]

Yeah what @BCP said. I'd email Randall first and see what he says. Email him at [email protected].

 

[msgriff]

Seems like a pretty straightforward install, but I understand your hesitancy. The only thing I would recommend is to get your shims from Precision Reflex if the MD needs to be timed. They are the only ones, that I know of, that include 0.002" shims. Others only go down to 0.003", and with a 15 ft/lb max torque and "hand grip only barrel vise", that might be useful. I'm surprised that BSF doesn't mention anything about threadlocker, like Rocksett.

How are you going to put a muzzle device on there? It's a carbon fiber tensioned barrel. There's no cutting it back to thread.

Yeah, what he said. Your barrel doesn’t have threads, nor does it have material to turn down and thread.

Randall is the man. But I don't think there's enough material at the muzzle end to add any threads. Nice barrel, but I think it has reached its final evolution.

 

[TurboTrout]

Pretty rifle, but I don’t see enough meat to thread properly

Send your upper to Dane at DMR Rifles in Vegas, that's child play for him.

How so?

 

[waveslayer]

How so?

In like shipping it? There should be two little pins you push, remove the upper half of the AR.
Then place in a box, use bubble wrap to secure it.
Then tape up
Ship to DMR Rifles.
What else can I help you with

Dane does incredible work, top notch in all respects (he’s built rifles for myself and buddies, all hammers) but I’d be skeptical if something like this would be easily doable, even for him.

I could be wrong but there doesn’t seem to be enough meat on the portion forward of the carbon wrapping, as others have said.

Explain the part where he threads it. Or at least look at the OP's pic before you get all snarky.

 

[waveslayer]

The carbon will have to be cut back. Look at the pic, looks like just a carbon sleeve

 

[TheOfficeT-Rex]

Cutting the carbon back kind of defeats the purpose of a CFW tension barrel. And then you'd just have a wobbly carbon sleeve on the end.

 

[TonyTheTiger]

The carbon is sleeve is tensioned in place and not glued to the barrel in any way if I understand BSF's explanation. What holds the carbon on when you remove the steel ahead of it? What is the barrel diameter under the sleeve? Is it enough to thread? Will the CF make a good shoulder for a muzzle to device to snug against?

Presumably, that shiny metal piece on the end of the barrel is what is giving tension to the carbon fiber, and is held in place by threading on the barrel. I do not know this, but that is my assumption. Being able to see the end of the barrel might give some additional insight. It would be trivial to add a muzzle brake to this barrel. I am assuming that the threading on this barrel is what holds that carbon fiber wrap tensioner thing on place.

OP's barrel has a very different muzzle:

EDIT: Found a video of how they make the BSF barrels - they're not bonded. You are correct, you could shorten the carbon, rethread, and recap the end to restore tension (the carbon is under compression, the steel tension. Not generally how carbon tubes are loaded).

I still stand by the assessment it would be a better idea to replace with a barrel that matches the desired config from the manufacturer, but it is not outside the realm of possible.

Be better off to just swap to a barrel like this, vs trying to machine a square peg into a round hole.

I agree.

Depending on how hard it is to do and the necessary skill level needed it may not be to much cheaper than a new barrel. With a new barrel you will at least get exactly what you want in the end. Who knows with the other route

Showed this thread to BSF and got a reply. Apparently I cannot add a muzzle device to this barrel. (((sigh)))

 

[Earnhardt]

Caliber?
Gas system?
Shooting factory ammo, or reloads?
Try using an AGB and a JP-SCS, or even a Titanium BCG, to lower the amount of recoil
Thanks

Did you explain to them that people on the internet said to just cut back the carbon fiber?
