I just purchased a factory 14" barrel and plan to have a Surefire FH permamently installed to bring the barrel length to 16". I went this route to save on cutting/gas port modifying fees for the 16" barrel.

Has anyone had any good experiences with any smiths or know of someone who has a lot of experience with the SCAR.

Also, what is an used 16" barrel with 1200rds worth?

Thanks in advance.

I hear of a lot of people doing this...shortening the barrel and adding a permanently attached muzzle device ......I've always wondered the reason..is it a look people are after?....would it not be more accurate/more velocity with more time in the rifled portion of a barrel...not knocking just finally decided to ask for my own info....Living in jersey...I've seen some people have had guns cut down several 4-6" and had some device attached...that would seem counterproductive to me.....thanks in advance:th_sign0163:

It has to do with NFA laws. Any <16" barrel requires a $200 tax stamp for SBR and NFA paperwork. Some folks may not be able to possess SBR due to state law, etc. There's many reasons.

I used Nefarious Arms and was very happy with his work and turn around time
Factory 14 with factory EPC hider for 16.1 "

That a Mepro true dot?

It reduces overall length without requiring NFA paperwork, which makes the package more compact and balanced - but particularly helps if you are hanging a can off the end.

As for accuracy, longer barrels (to a point) add more velocity and create an incrementally flatter trajectory as a result. The flatter trajectory (and a projectile that is stable longer) makes it EASIER to shoot accurately at distance.

However, all other factors being the same, a shorter barrel will be less susceptible to barrel whip and POI change due to heat increase and therefore have slightly MORE accuracy potential than the same barrel in a longer length. It comes with slight reductions in velocity, making holdovers and wind calls more important, but shorter is "stiffer" (perhaps it is better to describe it as "having less whip" instead of "stiffer") and this incrementally MORE accurate. Comparison has to be between exactly the same barrel specs, though. Naturally a 26 inch Bartlein is going to be more accurate than a 16 inch Green Mountain. A 16 inch Bartlein next to a 26 inch Bartlein of the same profile will have more accuracy potential, etc.

Thank you for the quick response. I'll reach out to Marvin and see what he can do for me.

To answer the why, Chainring was spot on.

Thanks everyone.

..thank you and i understand the shortening a 20" to a 16" ....i was more referring to a person taking a 16" barrel cutting it to 10" with a 6" pinned muzzle device (not can) its still 16" in length..just not as accurate/lower velocity under gassed(on di ar rifles)

Might help if you posted where you live, at least what state. Someone can give you a recommendation that's near by you.

Marvin does great work. another option is Tornado Technologies. they have done a few things for me and I have always been happy with the work.
