300blk upper build ??

[sgreen10]

so i recently finished my 5.56 build and decided to do a 300 blackout upper, I found a 16in barrel with a pistol length gas tube, anyone with any experience with this? would this cause issues with the buffer set up i have for my 5.56 or could i still just swap out the uppers

The reason for going with pistol gas length is to cycle subsonic when using suppressor.

thanks for the info, i ended up ordering the 16" from Aero Precision, and now just have to wait forever for my order to ship, (actually all my parts for this upper are waiting to be shipped from one place or another, well not the gas block or tube ill just snag one up at a shop)
