This skeletonized tube is excellent. The machining is very well done, the fit and finish is great, and it’s very solid. This tube does not have any chatter when you put a stock on, it locks up very tight.

Stupid simple to install/face mount, looks mean and cuts recoil like a brake should. If you’re getting one, and you don’t have a suppressor to mount yet do yourself a favor and get a bds too. The vertical fireball can mess with your sight picture depending on what you’re firing. Love it!

Excellent product one of the best on the market

Best option for my scar 15p hands down. Also check out the SCAR RSA they make it’s superior to OEM all day.

solid construction, good looks, 100% functional- what's not to love?! keep up the good work guys!

Fantastic product! I ordered it to replace a different folding tube. This this tube saved me a full pound off the back of the gun! It also locks up super tight. I was worried this tube would cause the stock to have more play, but the stock is rock solid in each detent! Much better than any buffer tube I’ve ever used. It also doesn’t hurt that it looks really bad ass on the gun!!!

Wanted to buy this and the Folding Stock/Brace Mount for 4.5mm Folding AKs. Will have to wait. Other than that, this is the first item to fully secure a SB tactical SBA3 with *Zero Wobble*. Machined piece with anodizing. Does the job it supposed to. Wish it came with inch/lbs torque recommendations.

The ST-6 is fantastic... not only is it aesthetically pleasing,it's rugged. The finish is great and the machine work is fantastic...The extra QD socket is also a bonus. One other thing is the shape of it on my check seems to fit better into my check bone pocket where standard buffer tube seems to be larger and not as comfortable. It fits well on my kp9, sig canebrake, M85 and anything else that does not require a standard buffer tube assembly.

Awesome product, mounted right up to my Sig MCX and fit a SB3 brace perfect!

Lightweight, slick looking, and goes great on my MCX. It can be a little stiff to adjust positions, but I don't move my stock much anyway, so not a big deal. Great piece!

Paired perfectly with my arsenal adapter. Beautiful fit and finish. Absolutely no complaints

Bought this to replace the stock pistol brace with a Magpul stock after I SBR'd an MCX pistol but still wanted the foldability of OEM stocks. Unscrewed the pistol brace from the 1913 adapter and installed the ST-6. Magpul CTR fits perfectly and now I have the best of both worlds - foldable stock but with my own choice of buttstock!
