Perfect (26/10/2009)

I bought this to mount my Magpul PRS stock. Assembled easily and with a nice fit. All of the parts were DPMS except the spring. Great buy.

Super priced product. (12/11/2009)

Easy to install. [...] Parts are exremely durable and made to last.

Excellent stuff! (14/04/2011)

I mounted this kit to Doublestar lower receiver and had no trouble whatsoever. Excellent product.

Great kit, don't hessitate, get it. (15/05/2012)

Only thing I would add is a warning about the buffer retainer and spring getting loose as you unscrew the tube. I was busy watching the takedown pin detent spring when the buffer retainer escaped. Spending quality time on the basement floor with a magnet looking for a spring isn't much fun.

Not really complete kit for all stocks (13/07/2012)

I purchased this kit to install a CAA SRS on my SPR 5.56 that came with an adjustable stock. The carbine stocks uses a backplate that has a tab which keeps it from rotating once the buffer tube is installed. The tube on the A2 conversion kit lacks such groove.

The threads on the A2 tube are also perfect to hold the pin that keeps the buffer from coming out. Once a backplate is added, the tube can't hold the pin. I must admit I have not tested the pin retention but measuring the width of the plate, the pin will barely touch the tube.

I'm still researching how (if) to use this but by no means this is an easy conversion or all inclusive kit for all applications.

Works Great (31/08/2012)

Installed this kit on multiple ARs. Works with standard A2 stock and MagPul PRS. Should work fine with any stock designed to use the A2 receiver extension/buffer tube.

Not sure why other reviewer had issues with installation. Sounds like they tried to use the carbine lock with the A2 tube -- this tube doesn't use a lock plate. Use assembly lube on threads and torque to correct specs.

Good kit (13/11/2012)

This kit is pretty good for the money. Heavy parts, built pretty strongly. They fit well. My only gripe is that it doesn't come with a castle nut wrench, which would have made my stock changing experience easier.

Good to go (11/09/2013)

Bought this for my precision AR build to go under a Magpul PRS Stock. Good quality, it went on easily, instructions were provided, and I'm happy with it. I'll be replacing the recoil spring with a flat wire spring (Hate the Spoooiiiinnnnggggg), but other than that it's good at what it does.

Great buy (07/03/2018)

Used this kit to replace an adjustable stock with a skeleton stock. Could not have been easier. Remember, when removing the stocks plate of an adjustable stock, that there is a spring back there and the buffer retaining spring is held in by the buffer tube. The buffer tube easily threads on and holds the retaining spring and you do not need to use a wrench to tighten the tube because the stock will hold it secure once installed. Your choice. I have bought two of these kits now and have no issues with either.
