Not sure if this is the right place for this question but .........
does anyone know where I can send a barreled upper to have the barrel cut down and threaded - WITH OUT having them remove the barrel and to take it one step further how about with out removing the gasblock ???????? or is this not possible thanks for any answers - except for the ones I don't want to hear

I don't know...
I think you could put an expanding mandrel into the rear of the upper and use a steady rest to cut the barrel off and/or trim after sawing. Then put it in a tailstock to do the threads. The crown would then have to be done with a hand crowner unless you true up a part of the barrel beyond the threads and go back to the steady rest. So I think it is definitely possible but your smith would have to have the expanding mandrel. B-man |
| you can cut a barrel down without removing it from the rifle with a saw and one of these as explained in Bryce Towsleys " gunsmithing made easy". If you can find a gunsmith who has one or is willing to buy one. But then you have an unthreaded muzzle, so more tools needed ( a die) to thread for a flash suppresser. which leads to :WHY?All of this can be easily done better in a lathe. A barrel vise, a wrench and 15 or 20 minutes with a hammer, block and punches and you'll have a bare barrel. |

I think I can do it without removing the bbl by using a mandrel locked into the upper and indicating the muzzle (on a lathe). It would need to be done with a steady rest-
I'm also curious as to why you don't want to remove the bbl. At any rate, I do that type of job quite a bit around here- it's 40.00. Shipped back to you in a day or 2. Sean |

I was wondering about not removing the barrel cause the gun I want done is my new Stag model 8 - I want it cut down to 14" and then I have a vortex flash hider to put on it. I was just worried about having someone remove the gas block and then not getting it back on correctly
if it was a DI gun I would have no worries at all about it |

Not the one in the Yellow Pages 458 |

If the OP is having the barrel shortened, wouldn't the gas port need to be modified as well for the new barrel length? or isn't that an issue with a piston system? It will depend on the finished length of the barrel, buffer, buffer spring, bolt, ammo. So there are a lot of variables at work here. If it were me, I would leave opening the gas port as the last resort if nothing else works to get the gun running smooth. |
