Great washers

Washer worked great at a good price and fast shipping. Still leaves me with four more to use. Happy with purchase. I used this with my KAK flash can slim micro and it worked great to time it the way I wanted.

Work Perfectly

by -

I use these on all my AR builds and find them to work perfectly with no issues. Primary Arms always has what I need at great prices and shipping is always fast.

Good to Go

by -

Nice packaging. Bought these to have a couple of spares and to finish a build I am working on. Will definitely buy again as needed.

Good producy

Nothing crazy to say as it’s just washers but they work well and it’s nice to have spares as I tend to experiment with muzzle devices and not all of them come with a washer. Will buy again.
