Ruger 10/22 Polyurethane Buffers.

Monkey Wrench is proud to offer our own Polyurethane Buffers for the 10/22.

I know what you’re thinking, “That all sounds good”, and “I’m sure my wife will want one for Christmas”, but first, let’s talk about “What“, “How” and “Why

What.
The Ruger 10/22, probably one of the most popular plinking rifles out there, is a great little gun. A simple, light design, user serviceable, accurate and affordable.  The little rifle lends itself to many tasks, ranging from youth firearms training, to the somewhat controversial “non-lethal” uses the Israeli Defense Forces have for it. It’s highly customizable, and the sky is the limit as far as selection of aftermarket parts go. What else could you want?

A highly customized and suppressed Ruger 10/22.


How.
The rifle functions using the simple and effective blowback system. After pulling the trigger and firing the round, the bolt blows back, resetting the trigger, and upon its return to battery, it will strip another round from the magazine, making the rifle ready to be fired again. Sounds simple enough.

However, there is a weak spot. As the bolt comes to its furthest point back, it needs to hit a buffer in order to stop and start its travel back forward. In this case, a hardened steel pin.



Here we see the bolt and the buffer pin, first separated, and then installed, showing their relation inside the receiver. Why is this a weak spot? For two simple reasons:

  1. Over time, the steel buffer pin will “egg out” the receiver hole it’s installed in. Remember, the steel bolt hits the buffer, the buffer pin is steel, and the receiver is cast aluminum. It is only a matter or time before this happens, and when it does happen, repair of the receiver will not be feasible due to the cost of the receiver.
  2. Sound. The sound that the bolt makes as it hits the buffer pin is a loud metallic “clang” that can clearly be heard. As the holes get elongated, as pointed out above, the now loose buffer pin will then make a metal-on-metal sound with a rattle to it, as it bounces around in the cast aluminum receiver.This sound is even more noticeable when the rifle is shot suppressed, and the loudest thing to the shooter is the action of the rifle.

And that brings us to “What“.

Monkey Wrench is proud to introduce to you, our very own Polyurethane buffer. A buffer made to the exact dimensions for the Ruger 10/22 receiver. Made from a high density black Polyurethane with a durometer rating of 80A, resistant to temperatures up to 180F, it is ideal for buffer usage.



Installation is simple.
After making sure the rifle is unloaded, simply remove the rifle from the stock by unscrewing the screw at the bottom of the stock, just forward of the magazine release.
Once it is out, located the buffer hole, the most rearward and top hole in the receiver, and tap out the steel buffer pin. Then, simply insert the new buffer. It may require some effort, as the holes in the receiver may be filled with dirt, grim and possibly burrs.
Once it’s in, reassemble the rifle, and you’re done!

Monkey Wrench will be selling these buffers in sets of 2, for $15, shipping USPS in the CONUS. Email me at dan@referenceonly.com if you’re interested!
