Always the best quality and price.

I can always count on Brownell's having exactly what I need for my 10/22 and AR-15 builds. Great quality and excellent price as well.

Great company

This is a great company to buy your AR needs. I just needed some shims and they got my order out quickly. I'll be ordering more.

Ben-4 upper

I really like this 416 style upper. One of the better looking uppers I own. The fit in my lower is perfect. I have not have time to go to range to shoot it, so I do have an opinion on how it performs!

Shims

Used it on my 6.5 Grendel, very easy to install, great value. I'm very satisfied with this product and I would definitely recommend it.

Worked great for timing my brake

I was able to get my muzzle brake lined up and timed correctly within minutes without any machining. Overall these shims worked great.

Perfect to have on hand

If your muzzle device needs to point in a particular direction such as most muzzle brakes then these shims are a perfect answer to fitting them properly. You simply add or subtract shims until you get the desired positioning with an acceptable amount of torque. That way you don't overtighten or loosely fit the device.
