This is fucking tempting for me. I want to build a 13.9 using this specific barrel, but I can't find the justification to do it.

Fallout3boi@reddit

My problem lies in the fact that I've build 7 ARs in the last year. And I would still like to do a URG-I clone, so what niche does this fill that my other ones don't?

The muzzle device for my can brought me to a cunthair past 16" p/w and it works perfectly with my M4RCO. That's about it, do not pass go, do not pay the government $200.

That’s it? Weak.

I’m kidding…Ive gone way too hard in the paint on these sales. I’ve been revenge buying after that disappointment that was the G$ blem sale.

If you’re not gonna pin and weld it’s but if not bro you’re gonna have a hard time finding a muzzle device that brings it to 16”. Btw the SureFire s3pf does not meet the criteria. Don’t ask me how I know 🤣

My 13.9 Core came from ADM P&W w/SF Warcomp to make 16" OAL. The 3 prong is only 0.03" shorter than the Warcomp. I have a 3P and a 4P installed on 13.9" barrels and they both make the 16" OAL just using the amount of washers I needed to time them

How short was it? Lol

brandonbambi@reddit

Like .15 inches short. Something minuscule like that

Is that with the AccuWasher?

I thought people were throwing the thickest AccuWasher on their Core 13.9 + SF3P to get it to 16in+ (but I've never actually done the math, nor have I measured it.)

No it’s without it and yeah you’re right. I emailed d Wilson for his pin and weld service and I asked if there was anyway I could bring my barrel to 16” using accu washers and he emailed me back saying “sorry but our barrel stretcher is broken”. And everywhere I look the websites say that they will not add washers to bring it to 16” so that’s another reason I don’t recommend this. I just gave up and made it a pistol.

His disclaimers do make me laugh. He must hate the Reddit Special builds.

Fair. I had been yearning for a 13.9 build but just decided it isn't worth it with my preferred SF muzzle device.

steelcityblue@reddit

Do any of the surefire muzzle devices get to 16" without help?

[-]

Radiant_Eagle7634@reddit

I wanna say the muzzle brake is longer and might, but I tend to go for prongs for better suppression.

[-]

halfyardstick@reddit

You can absolutely get to 16 with shims.

Huxwurx makes a 13.9 flashhider, but I don't know if I want to get into the Huxwurx ecosystem since I want to build a 14.5 URG-I with a RC2. My other concern is that fact that I don't have niche a 13.9 would fill(other than I wanted to build one).

dwood20001@reddit

Not sure what mounts you use if you’re shooting suppressed, but Liberty Precision makes a Plan B flash hider that’s P&W for a 13.9

[-]

Ice_Cold_Camper@reddit

Hear some justification my 13.9’s are the best shooting rifles I own for close to mid range. Perfectly gassed and shoot soft. Plus, if you get a 13 inch rail from G$ the suppresser locks in right under the lip and it looks bad add in my opinion. lol.

[-]

Drexx_Redblade@reddit

13.9 and 13.7 are better length for a suppressed GPR than 16. Assuming you run it as a pistol or SBR, pin and welding anything lower than a 14.5 is dumb.

I got an 8.5” 300aac for this same price last night.

I also watched some poor fucker pay $295 for one this afternoon on GAFS. I couldn’t say anything because I was also buying something from this same person, which was priced much better…..

Dear new GAFS user that paid 16% more for a used 8.5 “ Core, I’m sorry I have no shame.
