Slide our FDE rubber cover over your AR pistol buffer tube for protection with style. To ensure best fit, measure the ID of your buffer tube with calipers. This product fits tubes from 1.22" dia to 1.36" dia. Install using compressed air or copious amounts of gelled alcohol hand sanitizer. As tempting as it may be, do NOT use dish soap. Our FDE color is an excellent match to Magpul FDE. Other manufacturer's FDE color may vary. Made in USA from dipped rubber. Price is for a pair. Build one AR pistol and keep a spare cover in your parts box or build two AR pistols.
