Str8shooter Posted November 18, 2018 Report Posted November 18, 2018 Long story short. I’m dropping a BSF CF rifle length barrel into a PSA upper. Anyone done this and what is the correct length tube. I’ve seen different rifle length gas tubes and want to nail it first time.

98Z5V Posted November 20, 2018 Report Posted November 20, 2018 Do you have the PSA barrel already, in a complete upper, or are you working with stripped receiver sets? Or, are there PSA guys here that have posted their gas tube length protrusion into the upper receiver, and where that gas tube stops in relation to the cam pin cutout in the upper?

I have a complete upper that is carbine length. Gonna sell it. The barrel I am putting in is a full length. I was hoping someone had done this so I could pick their brain.

Well,check out that PSA barrel you have, and it will give you the insight that you need on this. Notice the gas tube protrusion into the upper receiver, and where it stops. What really matters, though, is how that new barrel maker drills their gasport. What gas system are they running on? It's either DPMS-based, which is AR15 gas tube lengths, or it's Armalite AR-10 gas tube lengths. Or, it's some weird hybrid shiit in between both of those lengths. BSF is the only ones that can answer this question for you - call them. I can tell you right now, PSA uses that fucked up hybrid gas length, and it sucks to deal with. Many other manufacturers are on that bandwagon now, too.

Str8shooter Posted November 26, 2018 Author Report Posted November 26, 2018 I am finding out a few things in this build. My hope is that it helps someone down the road.

Str8shooter Posted December 27, 2018 Author Report Posted December 27, 2018 Curious and excited too see how she wrings out.
98Z5V Posted January 22, 2019 Report Posted January 22, 2019 Any updates to this beast, man? Curious to see how this barrel does after it's got a few down the pipe.

Its ready to go though. I'm interested in testing out many things. The difference between the hellfire muzzle break and the suppressor also. I'm hoping to get out in the next month and test. When I do I will definately let you know. Edited January 22, 2019 by Str8shooter

edgecrusher Posted January 23, 2019 Report Posted January 23, 2019 It’s been -5 or -6 with wind chills in the -20’s when I’m out there. Absolutely brutal. It was a balmy 24 today with no wind, felt tropical

I got called in 6 hours early for that, been getting a lot of overtime due to the weather, which is nice. ?
