G&P mid-length outer barrel

[PopRocket123]

I'm planning a build based on the Munition Works Fixie LT. I'm using a G&P as a base that uses the tapered fitting for the outer barrel which already limits my options. The tricky part is that the magpul handguard I want to use requires a barrel with a mid length gas system in order to fit (yes I know there's a carbine length version of the same handguard, I prefer the look of the longer one).

I've found a barrel that looks like it would work for a mid length but it's hard to confirm without just buying a selection of barrels and seeing what fits.

Has anyone used this particular barrel before or have you found another one that definitely has the mid-length gas system? If I can't find on I have a 10.5 with a carbine length gas system that I'll just chop and add the length to.

If you can't find a taper barrel the right length, you could try one of these: https://www.firesupport.uk/gp-taper-outer-barrel-adaptor-for-aeg.html and a regular barrel.

Another option is get a used traditional g&p upper , they do pop up from time to time.

Isn't the Fixie LT a 14.5" barrel, though?

Yeah. Trouble is basically all 14.5 barrels have the shorter gas system since that's what the military rifles use. I was going to find a 3" barrel extension to stick on the end. From what I've found there are almost no outer barrels set for a mid length gas system since it's a civilian thing which most cloners aren't interested in

I haven't but I think my dad did a few years ago. It was a couple of sets of receivers, outer barrels and gearboxes. No full rifle but they were held up in customs and he got a call from them making sure they weren't gun parts
