Wrong gas tube but it works...

Recommended Posts

Interesting find. I didnt realize that my bear creek barrel truly needs a Armalite gas tube and not an AR15 length. It shoots great. No issues. 

 

I'm concerned but mostly interested in what issues follow. Since it functions great is a dirtier gun all I'm in for???

 

Thanks for any input

This is it. Bear creek barrel but with a melonited mid-length aero precision gas tube. Having no issues. 300-400est rounds down pipe. It appears to seal against the gas key to cycle properly...so is this the time to say, "If it ain't broke don't fix it" ????

I cant find a armalite ar10 mid length gas tube anywhere. That's what I'm reading is "correct " but no luck. Any help on locating one to make it right? 

Armalite only has carbine and rifle lengths in stock and listed but no mods at all...

 

Thanks for any help

Armalite doesn't make an AR-10 midlength gas tube.  The only thing they do for the AR-10 is Carbine length and Rifle length - and those numbers are different than AR15 gas tubes. 

What you're looking for is an Armalite AR-10 Carbine gas tube, which measures...

DPMS Gas Tube/AR 15/16

 

  Pistol             6-5/8

  Carbine          9-3/4

  Mid-Length  11-3/4

  Rifle             15-1/4

 

 

 

 

Armalite lengths,

 

Rifle ( 308 ) ----- 15.5 "

Carbine ( 308 )--12 1/16"

super SASS Carbine ( 308 )--11"

Super SASS< Rife (308 )   ?

Mid ,( 223 )------------------ 11 3/4"

Carbine ( 223) --------------- 9 3/4 "

Rifle ( 223 ) ------------------- 15 3/16"

AR15 National Match---------15 3/16"   (That's myinformation, from the one I have here...)
