Not sure if this helps -

The 14.5 measurement includes about .6 inches of thread for the muzzle device. You can subtract that amount from the length of your device (minus shim/washer thickness) and then add that number to barrel length to get a rough idea.

As an example GMB specs their muzzle threads at .63; if you use a .10 shim subtract that from .63 = .53; then subtract .53 from 2.67 = 2.14; then add 2.14 to 14.5 = 16.64.

This is a rough idea only, you need to get the parts in hand, seat a bolt in the barrel extension and measure with a rod from the bolt face to be certain.

Figuring that ATF was looking to hang it in my rear if they were ever measuring one of mine to see if it was 16, I cut an old one piece cleaning rod to a hair over 16 and measured it with several different rulers to make sure I was over 16. That way if it is level with or slightly under the end of the device I'd know it was good to go.

The gunsmith doing your pin and weld should make sure you are GTG, really not an issue if you are using a 14.5 inch barrel.

The 3 prong is longer than what Surefire lists on their site.

Hey guys, new to the site..
I have a new rifle (16in) that I'm debating re-barreling with a 14.5in and pinned/welded warcomp. I've seen 2.67 inches advertised as the spec for its length but when I measure it, it seems a bit longer around (2.73). Curious to see if anyone has done a pin/weld on a 14.5 and if so what was the final length from the bolt face? Thanks.

imo a complete waste of money. If and when you shoot the barrel out and want to go that route with a 14.5" pin and welded, have at it. But to go through all that trouble of getting a new barrel, pin/weld it and then have to go through the trouble of selling the 16" barrel, that's a whole lot of work for 1 1/2 inches.

just my opinion dough.

Could be a lower quality (PSA) barrel that the OP wants to replace with a Colt SOCOM or BCM 14.5 pencil profile for his intended purpose. You know, patrol or sniper support.

For the masses who read this in the future, the comment about PSA was made in jest based on another unnecessarily long thread about PSA quality running concurrently with this comment. Don’t search for it. Just know that the PSA story is the same as the Hyundai story and by the time you read this, they are awesome.

The sf devices are long enough to go shorter if desired. If you have a good barrel, a cutdown may be worth looking into. 13.7 w shim(maybe) or 14”.

Have a you tried the Wc yet. I've a CTN and having tried it on a few things it's meh unless you are mounting a can.

Thanks for the input guys. The rifle is a Stag 15 LEO. It was actually made by Aero which I thought was interesting. In the box was their bill to stag. I guess they’re both owned by wolf so that makes sense.

Anyway I decided I’m not gonna go ahead with the pin/weld. I’m just gonna put the money towards a AR pistol :) really not worth is for 1.5 inches.
The barrel chop would void the warranty/barrel guarantee which was half the reason I bought a stag kinda forgot about that part..

@Torquetard I haven’t shot it yet but I do a fair amount of night work so I figured I’d give it a go.

I have a 14” barrel with P/W open-tine Warcomp that measures exactly 16.25.” It is incrementally handier than a 16” barrel when suppressed with a mini-can. The cost of rebarreling a P/W barrel is inconsequential compared to the cost of actually shooting out said barrel.

I know what you mean. On the my recent 13.7 I used a JP Enterprises FH and came out at 16.1. When I showed the wife what I had accomplished - 2.3 inches less barrel showing out of my rail, she just rolled her eyes.

Unless this caliper is calibrated/verified, take this information with a grain of salt.

It May not be spot on but it agrees with my tape measure (not calibrated lol)

Is this better? The 249S Saker is listed at 2.750" and the Warcomp is the same length.

I believe you. Thanks for taking the time to get the calipers out! I may run the closed tine on the 16 instead. Gonna sabe the 3 prong for the coming pistol lol

The difference between the length of a 16" and a 14.5" barrel is noticeable IMO.

Personally do not like the pronged warcomp. I would probably time it neutrally and if you do that one of the openings in the tines faces straight down.

I ended up with the CTN warcomp.

My .308 has a 14" and a pin, and welded three prong open tine Warcomp. I will say that it's kind of annoying when it gets banged up against something and I have to hear that damn thing ring like a F word tuning fork. I wish I had gone with a 14.5 and the closed tine, but I didn't see it in .308. At least you don't notice it when shooting, and it works very well. Got one on my .300 BO SBR, and same thing... tuning fork... But they work.
