Only reason I went with the SOLGW over the BA was the gas length. I have 2 other BA barrels, one being the 16" Hanson and that barrel shoots spectacular. Far more accurate than I am capable of....

Huh, a middy might be interesting when I get around to building another one after I get a can. Didn't know they made that

Can I add a nuanced request? 13.7 with a DD RIS II? ...

I would also like to see if anyone has done this. From what I’ve read, the shortest barrel that would work with an M4A1 RIS II would be ~13.2” so it seems to me 13.7 should be a great fit with hopefully enough room for a QD suppressor.

My rail is a 12.65 and there is room. If running a QD, 13.2 will be really tight. Direct thread can would be perfect for that

When I ran DD RISII rails, I had two barrels cut down to 13-3/8” long and my 762SDN6 can had about an 1/8th of an inch gap between the end of can and the beginning of the rail.

Having Retro arms works cut down a Spikes 16" CHF barrel to 13.5"(Going to run on a sbr or pistol lower). Not a fan of pinned MD's; but should make for a good handling/velocity gun that I don't want to run a can on.

Good thread though for ideas on rails etc. I'll be joining the cool club soon

I’m definitely still looking for any possible photos if you have them? All I’ve been able to find are these, none of which are mine :)

Is 13.7 the schnizzle?

carbine or mid-length gas?

Ballistic Advantage makes a 13.7 carbine barrel. Rosco, SOLGW and a few others make a mid length. 13.7 is a great length, but getting the muzzle device to get it legal length leaves on a few options, especially when running a can.

I think getting the barrel of choice and cutting it down to 14'' would be ideal.

Not really.

I had retro arms just chop my 16" Spikes CHF to 13.4"(12.5-12.6 rail will fit perfect). Wanted a shorter gun to run with no can and have a little more velocity, and something different from my 11.5's, 14.5's and 16's. Will be run on a pistol lower or SBR lower depending on where I'm going. But I'm not a fan of pinned MD's especially with SBA3's around these days.

I don't really get the 13.7". Why not run a 14.5" with a shorter muzzle device? Instead of running a 13.7" with a long one to get to 16". Still at 16" overall either way; but you have more barrel/velo.

Love my 13.7. Noveske Infidel midlength barrel is a super soft shooter. It is definitely time to remove my uber rare Geiselle rail with the Keymod, and get me some Mlok

Here you go! Had to decipher my photo bucket account to get this one. However, I cannot find any with the suppressor mounted but from this pic you can tell the gap was minimal between can and rail.

SOLGW has something in the works for muzzle devices. No idea on details yet.

Noveske PDW with a 13.7 Infidel SS barrel and PW KX5. 13.5” NSR rail. Love the handling of it. Slightly muzzle heavy with the pig and the Cloud WML, but nothing crazy. Still forming an opinion on the TA44 optic.

This thread may be a bit biased, but does anyone think it would be worth it to get my 14.5 Colt M4 barrel cut down to 13.7? Its only 0.8” shorter, but is the 13.7 really feel that much easier to handle? Less weight? Just cooler and more social media worthy?

For what it’s worth, I am not bale to SBR at this time so 13.7 is the shortest I can really go, and this gun is currently wearing an ACOG TA31 (possibly wanting to piggy back an RMR in the future too). I also have an Aimpoint T2 on a Unity Tactical fast mount I might throw on from time to time.

I don't see a benefit to cutting a 14.5 to 13.7. My 13.7 with the Vortex Viper PST gen 2 and the AAC M4 2000 is not light at all. It is my fault because both of those weigh a lot more than gear that similar in comparison. When it comes to suppressors, you are really limited by going to a 13.7. I didn't want to use my M4 2000 on this one because it is a tank, but it was the only can I had that used a long enough muzzle device.

So I got this 6 years ago, from weaponoutfitters.com, these were a small batch made by micromoa-I guess they're pretty much the same. It's insanely awesome. Of course best results are with 77g, but honestly shooting 10" plates at 3-600yds with 55g and 62g with confidence is not a problem. This is a PERFECT mini-recce barrel, this rifle use to have a 1-6x, but not at the moment.

Commented on the other 13.7 thread but thought I’d comment here as well.

To start. 13.7 is the shit. Best looking no nfa rifle in my opinion you can build.

What are the options for a 13.7/13.9 in carbine? I like the fsp and quad rails (specifically the dd ris ii) and cannot find a carbine barrel in that measurement that’ll accept a front sight post. Ba stated there gas section isn’t long enough and their the only carbine 13.7 I know besides dark storm industries out of New York but there are no reviews on their barrels and cost over 250 shipped.

If I remember correctly micromoa made a middy 12.5 track some years ago. Unfortunately I believe they're out of biz. I wonder if Lilja would make a custom one

13.7" BA with 1/8" spacer on P&W Warcomp. Centurion CMR 12" rail. I just double checked and in actuality, they report their 12" rail is actually 12.56" long. Wt =10.7 oz w/their barrel nut.

I have tried a lot of different brands (Troy, Norgon, Norgon clones, etc) and the KAC unit is my favorite. It fits and works with the Geissele maritime bolt catch. It is long enough to provide good leverage.

Yankee Hill Phantom 7.62 QD Flash Hider works as well. ONLY THE 7.62 VERSION THOUGH. It's available in 1/2-28 threads, but if you get the 5.56 one you'll be unhappy.
