    A bit tight

    Posted by Unknown on 3rd Apr 2015

    I got the stock in and I wish I could give it 5 stars. The cheek weld is awesome and the stock is VERY comfortable. The reason it gets four stars is two fold; first, it was WAYYY to tight when I got it in. It took too people to adjust it, one pulling on the gun, one pulling on the stock. I will say it has loosened up to adjusted by one person now with a lot of effort (I guess it could be worse and it could wobble :)) my second issue only arises because of the first; you have to take the stock off to get to the storage tubes. I will never be using them as it is a complete pain to move the stock. I will finish by saying that I am incredibly happy with the stock's feel and while it may be too tight, it has ZERO WOBBLE.

    Nice and Wide

    This stock is great! The fit on my receiver extension is very tight, with only a tiny amount of fore to aft wobble, if the stock is fully extended. The extra width makes for a very comfortable cheek weld, and it ballances out legacy quad rail handguard systems. Be advised; the stock must be completely removed from the receiver extension, in order to access the two storage compartments. Overall, this is a great piece of kit.

    bravo b5 enhanced

    Excellent product, fit very good, very little rattle, fit and finish is excellent. The FDE is uniform and well balanced. The only thing I hadn't considered was that you need to remove the stock before opening the storage caps. I rate this piece 4.5 stars

    Great Stock

    Posted by Alan B on 25th Jun 2014

    Fits the buffer tube just right. No rattle at all. 87% better than any other stock I've used. I would feel so tier 1, if only mom would let me move out of her basement...

    Everything but the kitchen sink

    I was looking for a buttstock that I could put against my shoulder, get a good cheek weld on and attatch a QD, and this does all three without any extra bulk or unnecessary structure or gimmicks. It's rock solid and looks good.

    Great product! Great service!

    I knew the B5 SOPMOD was going to be an excellent product. I also knew the SKD Ninjas would be all over my order and get it to me ASAP. This is not my first time doing business with SKD and it won't be my last. The SKD Ninjas are right up there with the Keebler elves. SKD... Check!!!

    This stock is a great stock for any Ar-15 Pros: • Very Rugged • Comfortable • Snug fit on buffer tube Cons: • Not as well finished as I would like, but I’m not going for looks or finish I’m going for functionality! • It's a bit heavy I highly recomend this stock

    Love this stock!

    Just sold the LMT SOPMOD to replace it with this stock, for one reason only: the Anti-Rotation QD Socket. No more sling getting twisted!!! The B5 is a lot lighter in color than the LMT, but the Fit & Finish is just as good. SKD once again did not disappoint, with Ninja Fast Shipping.
