Fde version
I was quite surprised at the overall fit and finish on this piece. It really appears it could've been made by CZ! I also love the fact that I'm no longer stuck with the stock grip! The burst and fa markings are a nice touch. My only complaint is that it's such a great mod, I'm now going to have to purchase one in black! Any discount if you buy more than one, ha!

Bren 805 lower receiver FDE
Received this the other day, quality part that fit like the factory part, lines matched up with no gaps and tight fit. Only time will tell regarding how it holds up, but is a high quality part that I have no regrets installing to give me a better grip choice.

Lower Receiver
The fit and new grip angle is amazing. Doesn't feel as clunky as it used to and the fact I can switch out my grip with any AR grip is great. I also find the custom fire select makes my tacticool factor go up by 1%.
