Cons of pinning and welding a suppressor mount

[ODgreenpizza]

I don't get why any anyone would run a full size suppressor on an 11.5" barrel. It's the worst of both worlds.

It does allow you to use a 10" rail and eliminate clearance issues between can/mount/rail/etc.

Personally, I would not cut down the 16" barrel. If you really want to run a suppressor with a 14.5" barrel with a pinned and welded muzzle device, buy a new 14.5" Colt SOCOM barrel and save or sell the 16" barrel. Anytime you cut down a barrel, you have to account for gas port sizing unless you are running an adjustable gas block. Even then, you may still be under-gassed.

Colt 14.5" and 6920 barrels use the exact same gas port size.

confused by what youre saying here?

I would prefer buy a Colt Socom barrel rather than cut and crown what I have but they are not in stock anywhere except at "cloner" prices and I'm not paying $485 for one.

Thank you for the clarification Iraqgunz.

I quit working on guns that have a pinned muzzle device.

Cons are added expense.

Pros are use of a 14.5” barrel, shorter overall length.

An experienced Smith can remove a device later, if needed. Be damn sure to use an experienced smith to pin and weld. I’ve seen many hack jobs, some ruined devices and/or barrels.

And if its not concentric you can blow your can up too. Seems like a lot of cons, I would prefer to buy one from a BCM per se where the company do these things often. I wouldn't want Joe Gunsmith doing it. And I have 14.5's and 16's and I dont see that 1.5 inches worth the hassle. But peeps do it all the time, YMMV.

scottryan, your PM box is full. I have a question for you (unrelated to this thread).

Back to our regularly scheduled thread.

How would running a short suppressor on an 11.5" barrel be any different?

confused by what youre saying here?

A short barrel is used on an AR to keep the overall length short, but at the expense of velocity. If you install a full sized suppressor, you lose the advantage of the shorter length. Combining a longer suppressor with a shorter barrel gives you the same OAL but with less velocity, the worst of both worlds.

If you're gonna go short, go short.
