george_995 Posted May 27, 2014 Report Share Posted May 27, 2014 (edited) Anyone try one of these yet from rubber city armory? Instead of an adjustable gasblock you adjust the gas from the carrier key. At $45 I am willing to try one out for my 308ar that needs an adjustable GB. I like this because of its price at $45 and if you do not have an adjustable on your rifle you aren't stuck with your original non adj. GB. Parts are good to have on the side for future builds, but say you paid $60 for a vltor originally and now shell out $100 for a syrac or etc., thats $160 (without shipping) you got into Gas blocks. This is assuming from a build standpoint. https://www.rubbercityarmory.com/scripts/prodView.asp?idproduct=33 Edited May 27, 2014 by george_995 Quote Link to comment Share on other sites More sharing options...
gnatshooter Posted May 27, 2014 Report Share Posted May 27, 2014 That's a very interesting piece of tech. According to the blurb, "Gas flow is adjusted and maintained at the carrier with 2 set screws. One to adjust gas flow and one to lock it in place." With a setup like that, the designers were apparently concerned about the unit going 'out of adjustment' after lots of rounds. So I'd guess you'd need to run quite a few rounds through the unit to see if the gas flow setting holds true. Quote Link to comment Share on other sites More sharing options...
blue109 Posted May 27, 2014 Report Share Posted May 27, 2014 was looking at the light weight bcg and saw that. looks pretty neat! Quote Link to comment Share on other sites More sharing options...
washguy Posted May 27, 2014 Report Share Posted May 27, 2014 Nope get an adj gb.....so what you have with this is the carrier held in place by basically one bolt. the other isnt tight cause its being used for gas flow....so the end result is a non staked carrier bolt thats loose for flow.....nah :) Wash Quote Link to comment Share on other sites More sharing options...

Looks like on the tube portion there is the adjustment screw, and I am guessing on the left of the carrier key tube is the set screw out of picture.

StainTrain Posted May 28, 2014 Report Share Posted May 28, 2014 If your adjustment screw in your block backs out or vibrates in (non-syrac blocks), you can fix it fairly quickly without breaking down the weapon. If that thing backs out, then you have to breakdown the weapon. What if all that expansion and contraction causes that little screw to come loose in your upper, it may not be catastrophic, but it likely won't be good.

True enough, but with this thang people won't have to drill holes in their handguard with adjusting the gas block. And access is easy enough, you drop the bolt carrier group for cleaning anyhow, piece of cake. Quote Link to comment Share on other sites More sharing options...
blue109 Posted May 28, 2014 Report Share Posted May 28, 2014 I think its a cool idea for a single setting gun. not so much if you plan on using different setting for different ammo/configurations. dial it in and thread lock it. Quote Link to comment Share on other sites More sharing options...
dsdmmat Posted May 28, 2014 Report Share Posted May 28, 2014 I don't know about controlling the flow of the gas at the end of the gas tube verses the source of the gas. Seems like a neat Idea but controlling it at the source seems to be the better way to go. Of course there are many ways to skin a cat so, to each his own.

survivalshop Posted May 28, 2014 Report Share Posted May 28, 2014 Not sure how efficient this system would be , you only have a short window of gas pressure at the Carrier Key itself. Interesting idea though , guess who has to pick one up & try it & report back . We have a rule around here . <thumbsup> Quote Link to comment Share on other sites More sharing options...
