Frankly Posted August 9, 2021 Share Posted August 9, 2021 Been looking for the right kind of stiff plastic "wire" that could do a near 90º bend with heat. If it were 5-8" long you could insert it into your barrel from the muzzle and poke the L-shaped tip up into the gas block (before mounting gas tube!). This would be a solid visual check that your gas block is aligned so you can mark position, punch for dimpling, etc. I know we all have work arounds and things like the SLR Rifleworks jigs for aligning our gas blocks but I like "seeing" to be sure. Plus it's simple and works on any diameter barrel. Wondering if there is an existing automotive or tech product that might be similar? Or a lead to where some could buy a couple feet of stiff plastic rod that is still bendable and small enough to fit most gas holes? I doubt there'd be enough profit to make them as a mass product but maybe some plasticy tool place like Real Avid already did this? At the very least they'd be good for scratching your leg inside a cast or maybe for probing some yucky drain pipe Link to comment Share on other sites More sharing options...
Southpaw Posted August 9, 2021 Share Posted August 9, 2021 Maybe this is what you're looking for? I've never tried it. https://www.brownells.com/gunsmith-tools-supplies/rifle-tools/gas-system-tools/ar-15-gas-block-aligner-prod68371.aspx Link to comment Share on other sites More sharing options...

Even better is the comment in the reviews where the guy found a strand of uncooked spaghetti worked even better! Thank you! Link to comment Share on other sites More sharing options...

In his 2nd method the problem could be the distance from the gas shoulder on the barrel can be off (too far or too short) depending on gb variations. I use a bore scope too check alignment.

obsessiveshooter Posted December 28, 2021 Share Posted December 28, 2021 Cover one end, blow into the other and you can hear when the block is lined up. Link to comment Share on other sites More sharing options...
gerritm Posted December 28, 2021 Share Posted December 28, 2021 Piece of uncooked spaghetti noodle works. Put it in the block rotate until it drops and mark, punch, install. the knock out with cleaning rod. Real easy & cheap. geritm Link to comment Share on other sites More sharing options...
PacMan Posted January 20, 2022 Share Posted January 20, 2022 https://www.brownells.com/gunsmith-tools-supplies/rifle-tools/gas-system-tools/gas-block-genie-ar-15-gas-block-alignment-tool-prod124593.aspx I used this little plastic device and a sharpie to locate & mark the barrel for the exact alignment. It will also allow you to indicate on the barrel how far should the gas block be inserted for those barrels made for front sight tower. Watch the imbedded video on Brownells product page for clarity on how to use it. Link to comment Share on other sites More sharing options...
