Q: I have the US0102 RS-2029 RS7543 adjustable block.
What rebuild kit number is required?
A: Kenneth, the Rebuild Kit for your application will be based on the Plunger you’re using. The Rebuild Kits are all identical except for Plunger size. If you’re using the Plunger that came assembled in your Gas Control that’s a #917. If not, select the Rebuild Kit size that matches your Plunger.
Q: In the "installation and use guide" there is a reference to an "alignment jig." I have purchased a dimple jig in order to precisely dimple my barrel, and I am interested in a gas block pinning jig. Since the hole for pinning the gas block is pre-drilled, do you or does anyone you are aware of make a gas block pinning jig that is compatible with my model RS7543?
A: Due to the popularity of Nitride-finished barrels the DIY jig has been discontinued. The surface on Nitride barrels is so hard that it was extremely difficult and inconsistent to get good results using the DIY jig with common tools that an enthusiast would have at home. Rather than make an overly expensive jig that most shooters would only use a couple times we've set up the pinning service for a very reasonable price. We may revisit a DIY jig in the future as engineering resources allow, but have established a pinning service instead (see the "Barrel Pinning" page in the Gas Controls category).

Q: Do I need to use a straight gas tube? I've been having gas issues with an LR 308. 20in barrel, rifle length has tube that is 15 1/4" long. But the gas tube has the bend in it. Will your gas tube line up properly with a configuration that originally came with a curve tube??
A: A a straight gas tube is required. We offer those in Rifle length here on the site. Thanks for your interest in Riflespeed!
