I'm building a 3 gun rifle. We shoot a lot of CQB type stuff at our local match and I want a light, short rifle. My plan is a 13.7" barrel with a pinned Primary Weapons FSC556 flash/comp that is 2.75". However, I intend to go to some bigger matches that will have shots out to 300 yds. What kind of accuracy can I expect out of this barrel? How does it compare in weight to a M4 barrel?

If the 13.7 shoots sub MOA with heavy ammo, why the need for a longer barrel?

I shoot my 13.7 with a perm kx3 for 3 guns and its great. Its a little heavier than an an m4 barrel but the extra weight helps a little with muzzle rise for me so i have faster follow on shots at around 50-75m. I like the barrel alot, and noveske obviously has no issues with quality. If i had to do it again, i would go with an aac or surefire brake and get a can for it later!
Best of luck

ETA: I forgot to reply to the original question....Ive shot at 3 and 400 with 75 gr BTHP black hills and was hitting 12" steel with no issues
and prvi partisan 55gr FMJ and had the same results. I think youve got a good 3 gun gun () in the works!

I had one. It shot great. Was a little heavy though, with the LaRue rail and KX3, plus the Noveske machine gun weight barrel...

I have a Noveske 13.7" upper with the perm attached KX3. It is MOA or sub-MOA with the 50/60 grain v-max and the 77 grain Sierra BTHP's. It outshoots my 16.1" Noveske upper. I'm sure its heavier than an M4 barrel but I'm not sure by how much.

I shoot 300M targets out of my 10.5 LMT with 62grn M855's so you should have no problems shooting out to that range with a 13.7 Noveske and better ammo.

Just make sure that the FSC556 is actually 2.75" I have to check the length on mine when I get home and on PWS' website the FSC556 is listed as 2.10" and the Quickcomp is 2.3". I have both and on top of that, 1/4" of that goes over the threaded portion of your barrel. I don't believe that you will get the 16" you're looking for in a 13.7" barrel. Might want to consider SBR'ing the lower, or going to their 14.5".

ah, good call, i got some incorrect info somewhere. thanks for the heads up. looks like the quickcomp might make it but i would definately need to check on it first.

back to the drawing board
