Great product
Received this kit, I thought not only was it a great deal but once I got it in hand I really liked it. The grip and stock have a great texture and the trigger has a good pull. I would recommend this kit it has everything you need!

Great Little Kit!
This kit is awesome! Very lightweight stock. The upper part where your cheek goes feels just a little softer, and it really makes your cheek weld comfortable. The trigger is nothing special, but really, what do you expect with this kit? A good trigger kit is the same price as this entire kit. It works nicely, feels fairly smooth, no excessive takeup, it just feels a hair better than some other cheap triggers I’ve used. The grip is extremely comfortable. I have large hands. The A2 grip is not great for my hand. This has a nice texture to it and is a little wider than standard grips. I purchased one kit, got it in, got it installed, then decided I needed another for another build. I just used the “OEM LPK” on each two kits I purchased. No issues. For what you’re getting, this is a great kit. BRD shipped mine pretty quick.
What rifles I would install this on depends on the rest of the setup. As I mentioned, this stock is very lightweight, which worked great on my Diamondback upper assembly with 16″ barrel and lightweight MLOK handguard. I tried it out on my PSA 18″ barreled upper, that has a heavier free-float handguard with Pic rails on all four sides at each end, but not full length. It’s a pretty beefy handguard. When I swapped the upper over to the lower with this kit installed, I didn’t like it. It was too front heavy. For that rifle or similar setups, I’d stick with a little heavier stock, like the Leapers UTG AR-15 PRO Model 4 Combat Ops S1 that came with my rifle when I got it.
The FDE color matched well with my Aero Precision Cerakote lower and Diamondback upper. That is one thing I was worried about.
Like I said, already have another on the way. Great kit for a great price. BRD has been my go-to for 3 builds now, and they’re the first place I check when I’m planning more builds.
