Archived [ARCHIVED THREAD] - SPR Barrel - Gas Port Size
Posted: 1/20/2019 1:30:51 AM EDT
What is the ideal gas port size for a 18" SPR barrel, with a rifle gas system, to run reliably suppressed with an Allen Engineering AEM5 (Ops Inc. 12th Model Clone)?

I think Crane spec is right around .1. I've sent an email to Compass Lake to see if they'll share. My WOA measured .108 and research shows Ballistic Advantage is .0935 which is typical of 20" barrels I believe.

My ended up with a 16” Rainier Ultramatch Mod 2, but they told me the 18” version had a .098” port

Thanks guys!

@Outrider

Are you running your WOA suppressed?  If so, were there any issues?

I just got the barrel so I haven't had a chance to shoot it. I'm also planning to chop it so I may need that sized port. I'll run it with an AEM5.
