Question on a 11.5” gas system and PSA build? Login/Join 
Member
posted
I’m looking to get an 11.5” upper and have a couple questions.

First, if I cut down a 16” carbine barrel will it be reliable as an 11.5”?

Second, any issues with PSA long term? I’m looking for a reliable gun but not at BCM or DD prices.


I have a DD carbine that is my number one and a PSA upper, the one I’m thinking of cutting down, that has ran well but I’m only about 500rds in.

It will work but why not just buy a new barrel like the one above?

It didn’t occur to me, doh.

Then I’d have another barrel laying around which would turn into another gun. Win!

I have a PSA 10.5” upper. Run it w/ and w/o a suppressor. No problems whatsoever. Decent accuracy as well. I suspect you would have no problems.

Just buy a new PSA upper - on the assumption you are making a 11.5" AR pistol or a Short Barreled Rifle.

11.5" PSA Upper with $229 w/BCG & CH.

10.5" PSA Pistol kit, everything but the lower.

^Thus the second part of my question as I’m looking at those as well.

Yup, I'd buy a barrel vs. cutting one down. I really like Faxon

The gas port sizes are different if you cut down a 16 inch. I believe they are substantially larger, 20-40% or so (going off faded memory) on the 11.5 vs the 16. You'll have to research the correct gas port size and buy the correct drill bit to make the hole larger.

This day and age? Just buy the 11.5 upper.

BCM had a article years ago on why the 11.5 was superior to the 10.5.

I bought a Colt 11.5 subsequently, and it works flawlessly.

I had an 11.5 mid length Faxon. It was really reliable and accurate. People will try to say that 11.5 is too short for mid length gas. I disagree.
