Just what the title says. I am looking for an 18 inch barrel with pinned FSB and rifle gas. I prefer a pencil profile, or at least something better than government profile. I am not a big fan of parkerization, either, but I can live with it. The closest I can find is this

https://www.tntesales.com/fn-usa-5-56-18-m16-a4-barrel-1-7-4150-cl-w-fsb/

are there any other straightforward options? I prefer not to do this custom, but I might if I were confident that it would be gassed properly.  

thanks

I would just buy an 18" rifle length barrel and do a setscrew conversion on a take-off FSB.  Other option is to send it to ADCO or similar to have FSB pinned.

These are your options.


And do the research into some of the issues with TNTE sales.

Ballistic Advantage will do it. Just add the FSB in the drop down menu. Definitely don't pay full price though. Wait for a sale (Labor Day, Black Friday) or make an account and then put it in your cart. Then wait a few days and they'll send you a coupon code.

I got a BA 18" 5.56 SPR with an FSB for like $150 on Black Friday sale last year. It shoots really well but it is HEAVY.

The only 18" rifle gas barrels BA has are heavy (SPR) profile.

You could buy a blem Faxon gunner and then send it to John at Retro Arms Works, for another inexpensive option. The "gunner" profile is nice and light.

18" Criterion Cores are in stock a lot of places. Get one and send to Retro Arms to have a FSB pinned.

Thanks for the responses. I have a couple of gunners that I like, I'll probably end up sending another off to get the FSB installed.

I have a 18 inch criterion core i used. Bought it of the ee and had John Thomas pin it with a fixed front sight for a retro build. Turned out amazing and shoots great. I have a hard time posting pics from my phone you can IM me if ypu want to see a pic of it.

Thanks, I am not wanting to go heavy with this set-up. The Criterion Core 18 inch has my attention, but I may cheap out and stay with the gunner.

Don’t cheap out. Save and get the criterion barrel. You won’t regret it.

This man is correct. Cheap barrels are sad. Criterion barrels are very accurate
