Retro B5 stock
I really like the quality and the price. It’s great to see Brownells pay attention to the Retro rifles. This stock went onto my Colt 733 clone and really looks the part.

Awesome!
What a great stock. I’ve got multiple of these on different lowers, and they work awesome. The fit the milspec tubes I’ve used without issue. The polymer has a nice finish and the adjustment works well. I will use this again in the future! Best retro looking stock for the money.
