Why a pistol-length gas system on a 10.5" barrel? Am I missing something?

[nate89]

I agree. I was under the impression the carbine gas system was designed for the 10.5" barreled Colt, but I could very well be wrong. I have never seen a pistol length gas system on a 10.5" barrel before, unless is was a 300 BLK which is completely different.

I don't know enough to have an opinion, but just like the often repeated discussion of dwell time and the 10.5 vs 11.5 barrel, could it be a trade off? Running extremely hard but more reliable than the same gun would be with carbine gas?

I bought a 10.5" Radical Firearms upper for my pistol build. It came with a carbine length tube. Runs great.

They must have updated the ad. It says carbine length now.

Are you Lawson11B? If so, I enjoy your YouTube videos. I just got an ALG SCB and your timing video helped a good bit.

Well it's past time for my update so here goes. I picked up a seekins 10.5 300 from radical and because I was doing it on the cheap I ended up getting a pistol lower from palmetto and a bcg from another unnamed source. I thought I had an issue after 5 fte's. Pulled the big to look it over and low and behold the pin extractor was missing. Pulled a bolt from another gun and viola she runs like a monkey on a greased slide. Kudos to the folks at radical for putting out a quality product.
