Rifle length gas tube source


enragged

Recommended Posts

Just recently got my PSA-10 and have read a lot on them here, so purchased the KAW Valley Precision stock hardware kit with the stiffer spring and 5.6 oz buffer since the Armalite kit has been out of stock for some time.  I am currently trying to find a rifle length gas tube since of course they are still shipping with the gas tubes too short.  I am hoping someone has purchased one from somewhere other than Armalite since those are back ordered as well.  Any help would be appreciated!

I know that I am a little late to the party, but here are some different lengths of gas tubes. 

 

https://truenortharms.com/ar15_default_store_view/gas-tubes-for-ar-15-ar-10-stainless-1.html

rifle length 15.675"

https://andersonmanufacturing.com/am-10-gas-tube-rifle-length.html

rifle length 15.5"

rifle length 15.25" but also says its for an AR-15 also so I'm not sure that it would properly clear the barrel nut

This is not a rifle length gas tube that I've ever seen used before.  Ever.  By any barrel manufacturer.

Ever. 

Might be a typo on his part, TNA doesn't list a 15.675" but the do list a 15-3/8" which = 15.375"

Here are the numbers provided by TNA

Distance to gas block shoulder        Gas tube size

9 7/8"                                                  11.75" (AR-15 Midlength)

13 1/4"                                                 15.125" (AR-15 Rifle)

10 1/8"                                                 12 1/2" (AR-10 Midlength)

13 1/2"                                                 15 3/8" (AR-10 Rifle)

0.300" is a pretty giant mistake, for a gas tube length.  That's a third of an inch, and no small mistake by any means.  Nobody has ever used a rifle length gas tube, on that measurement.

For someone showing up here and "setting a record straight" - setting us all straight on gas tube lengths -that's a major fuk-up.   And, it's a reason for me to question anything that @Censored_germ ever states for fact in the future. 

But, that's just my $0.02 on it.  Whatever that's worth.
