Excellent Service and Support
Every time I deal with Brownells, it proves, over and over, why I continue to purchase through them. Pricing is competitive, knowledge and service level is a step above. Nothing bad to say.

Solid part.
Part was true to spec and worked with Magpul fixed stock. Brownells is hard to beat. Shipping was a bit slower than I’m used to from Brownells, but this was ordered during Shot Show week, so it’s fine.
