    Looks like the UBR stock, which is currently in production. Has been for a while too.

    This is the UBR stock, it’s been out on the market for awhile.

    The patent seems to describe the magpul UBR stock.

    • Thanks guys, I forgot about that stock. I updated the blog post.

  • Nadnerbus

    Wow, and a $265 MSRP for a large piece of injection molded plastic. No wonder Magpul is doing well. The polymer empire.

    Why wait till now?

    The UBR is a nice stock. It is heavy tho compare to other stocks. It predecessor was the M93 robot leg which was complicated to install. Magpul sold the rights to Falcon and they made needed improvements to it.

  • MrMaigo: The application was filed back in February 2008. The USPTO has only now published the application. Inventors can request that the application be withheld from publication until its is declined or approved. The patent was awarded at the end of July.

    Yeah it does cost quite a lot of money for the stock. That’s the main reason why I didn’t built a lower using it.

    The Falcon F93 cost $150 and does the same thing. A better deal if someone is looking for that kind of setup. I’m thinking about getting one in the near future.

    Out of the all the stock that Mapul makes the CTR is the best for the money IMO. The ACS is really nice tho. I own both of them and the ACS has much better check weld than the CTR. What I don’t like about the ACS is magpul nickel and dimming their customers. $14 for a small piece of QD mount point that should have been included on the stock. CAA stock came with two QD mount point and that stock cost less than $60 when I bought it.

    Out of all the AR15 stock I own (12 I think) the CAA stock is by far the best value for the money.

    Daniel: Ahh, well… that explains that

    The old M93 stock looked pretty cool, IMHO; but I like space guns. 🙂

    The interesting thing about it, was that it was designed to be part of a modular system. the lower half of it could be removed and replaced with a piece that held 3 40mm grenades, or a watertight storage compartment, or a battery storage compartment, or a fixed stock, or a precision target stock.

    Seems like a great idea; presumably there just wasn’t enough market demand for such an arrangement. The grenade storage unit at the least seems like a decent idea; but presumably in a military situation it’s not as useful as it may seem at first.

    I’d like to see a lower replacement unit for the UBR that provided a magazine carrier. Almost as good as a redi-mag, but without the extra width.

    You know, the first thing I thought when I saw the picture was “cool gun!” Then I saw it was a stock. Oh well. Still, a gun that shape would be p. rad.
