- Simple, Yet SatisfyingBarrel nut shims are not the first thing thing - or even the 7th thing you think of when installing a new quad-rail or keymod handguard onto your rifle, but they go a long way to help time things and make them line up with your receiver.
I try to keep a couple handy so I can tweak and customize my rifle, or the rifles of buddies and keep the spacing and everything lined up.
- Good shimsMaybe you'll be lucky, and that barrel nut for your new handguard will line up perfectly without being timed?
I wasn't so lucky, but these fixed me right up. Good, quality shims.
- Time saverI bought 2 sizes of these so I would prepared for my new handguard install. Works as they should, no issues.
