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.

Measure and compare.  Start there.

LOL  thats why I was hoping I could go off of prior experiance instead of dancing around.  I wasn't wanting to take the gas block of another ar to fit test.

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.  :thumbup:

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.

Mystery solved.  15.25" will be perfect.

That's DPMS-based - which is AR15-based.  Good to know.  :thumbup:

I am finding out a few things in this build.  My hope is that it helps someone down the road.

That is what we try to do on this site.

Thanks for helping others by reporting your experiences.:thumbup:

Any updates to this beast, man?  Curious to see how this barrel does after it's got a few down the pipe.   :thumbup:

I wish,  its been crazy cold and crappy every day I have been off.  I've built a new 300 BO while waiting to get out and test.  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.

yeah yesterday, I had to direct traffic on an alternate route for 4 hours in the cold due to the interstate shutting down from 10 semis crashing around the same area. I got called in 6 hours early for that, been getting a lot of overtime due to the weather, which is nice. ?
