It is always a struggle to torque the castle nut on an AR. Really needs three hands to hold back on the buffer tube, hold the castle nut wrench in place, and pull on the torque wrench. If you don’t keep the buffer tube aligned it can be damaged by the tooth on the lower receiver’s back plate. At the minimum. You might end up with a buffer tube that’s not clocked right. This tool works well to hold your lower receiver and buffer tube firmly and in alignment so you can torque and stake the castle nut. I did try this with several brands of billet and forged receivers and they all fit fine. Does not require a large amount of torque to secure the buffer tube in the clamp so just snug it up with your fingers. The screw underneath adjusts the height for AR15 or AR10 receivers. Again, doesn’t need to be tight, the slot in the tool holds the buffer tube clamp from rotating and leaves your hands free to operate the torque wrench.

I’m working on tuning a blowback AR45 and the heaviest buffer I have found is 11 oz. I’m going to try swapping the standard carbine buffer tube for an A5 length tube so I can add this weight and see how it shoots. I believe this weight is the correct thickness to compensate for the added length of the A5 tube but I haven’t assembled it yet to verify the travel.

I know these have been around for a while but I had never seen one before. I bought it to try out a longer buffer tube with a version of Blowback9’s Gentle Recoil System and also with Taccom’s Adjustable Recoil System. With the longer length I should be able to fit many different combos of buffers and Kynshot weights and buffer springs. I found it fit perfectly snug on a milspec A2 tube and the whole assembly is light weight. It is a stock not a brace so I’ll either need to keep a 16” barrel or a p&w setup on it or buy a tax stamp but for now I’m going to run it with an Odin Works 5” p&w lightweight barrel to get to 16”.
