Great stock - Magpul Industries UBR Gen2 Collapsible AR15/AR10 Carbine Stock

I am very pleased with the stock. The build quality is amazing with little to no movement when locked in position. Be aware that this stock is heavy! I knew it was based on other reviews and that was fine with me as using it with a 20" inch build that will be on a bipod most of the time going for distance. Overall very happy with the purchase and I love the look.

Please be aware: I did lots of research into the A5 system that this stock is designed to work with. The buffer tube that comes with the stock is in between carbine and rifle length. The buffer tube is designed to accept the A5 spring and buffer that was designed by a company by the name of Vltor. My research showed the idea behind the system is to get the reliability benefits of the rifle buffer system with a collapsible stock (did not exist until the A5), you either had to go carbine or fixed rifle. I liked this concept so first ordered the stock and was excited to put in the A5 buffer and spring it's designed for (rifle spring with a proprietary buffer Vltor A5H2 which weighs in at 5.33oz). Come to find out after I received and installed the stock that the A5 buffer made by Vltor is completely sold out EVERYWHERE, and trust me I searched. You can go up or down in buffer weights but the standard A5 buffer at 5.33oz can not be found anywhere.

luckily, this stock comes with a spacer that is designed to go into the stock before the spring and allow you to run a carbine length spring with carbine buffer (or whichever weight you deem appropriate). I was truly looking forward to getting all that I could out of this new A5 system but unfortunately had to settle for the carbine setup with the spacer. Not a deal breaker and I'm not finished with my build so can not comment on the functionality, but figure when and if the A5 buffer becomes available from Vltor I will switch it out if inclined to do so.

Hope I saved you some time. Good luck!
