One Tool For Disassembling & Reassembling Buttstocks

Our handy, compact tool is uniquely designed to combine several tools into one. It has a spanner wrench that fits the receiver extension castle nut on M4-style collapsible buttstocks, with interchangeable pins to fit nuts with both old (round) and new (square) teeth, so you're ready for whatever type of nut is on the gun in front of you. Pins for both styles are included and easily changed by loosening a hex screw in the tool. For fixed rifle buttstocks, there's a screwdriver blade to remove the buttplate screws and a wrench for the nut on the receiver extension (buffer) tube. There's even a ½" square opening for a torque wrench, and even a hole for hanging the tool on your peg-board. Fits easily in a range bag or in your pocket for use outside the shop.

SPECS: Steel, black. 7" (17.8cm) long. Includes pins for old- and new-style stock ring retainers.

Great tool (16/09/2009)

This is a solid and effective tool for its stated purpose.

Awsome (16/09/2011)

This wrench is awsome, perfict fit, works great..

Spend the money to get great tools not cheap ones!

Very nice tool (29/02/2012)

This one works as advertised. It's very durable and functional, though a bit pricey. But you get what you pay for...

Solid Tool! Worth the Price! (23/02/2014)

This wrench is solid! The replacable pin is a great feature. My only recommendation would be to machine a place somewhere on the wrench to store the other pin when not in use.

M16/M4 Buttstock Tool by BROWNELLS (15/03/2014)

If you want the best this is the one to get . Fit, feel and finish is second to none. Well worth the money.

Well made. Inspired confidence. (01/04/2014)

I purchased this tool with some concern. I have an older AR-15 that had a 2 position collapsible stock with the 2 round holes instead of the normal castle nut and were well staked in place. I had been told how difficult some staked castle nuts were to remove. A friend who has built several AR-15's suggested just cutting the castle nut with a dremel which would likely destroy the tube as well. I wanted to remove the parts but retain them for collectors purposes and switch them out for a current 6 position stock tube. I just clamped the lower receiver in a vise using Brownells rubber faced vise jaws and was able to remove the ring without damage to the lower or the castle nut. I did tap the wrench with a plastic mallet several times before attempting to loosen the castle nut. This tool worked like a charm and I have already told several other people how well it worked. Brownells guarantee gave me the confidence to try it myself instead of paying someone else to remove the stock nut for me.

Great tool, just one hiccup (22/11/2015)

So I gave this 5 stars, despite my hiccup.

This tool is great, it's really well made and feels incredibly sturdy.

My hiccup occurred because I used it on a barrel nut, not a buttstock. If you're using this for your buttstock, no need to read any further...

The Centurion CMR handguard does not come with a tool. Centurion says that you should use a buttstock tool to install the barrel nut since it is the same diameter as the castlenut on a carbine stock. The problem is that you have to use a tool that has one "nub" on it, not three like most others have. These "nubs" aren't meant to torque a barrel nut to 30ft/lbs.

I used my generic amazon AR15 tool to install the barrel nut and caused the "nub" to break off. I bought this thinking it may work for me. This tool has a small replaceable pin (as pictured), which bent and became unusable almost instantly. Luckily, I was able to use a 1/8in punch in the hole perfectly fine.

I'm still 100% happy with this tool, the pin broke because it wasn't designed for the torque but luckily it has a great design where you can replace the pin.

Obviously, the only thing I would change about this is tool is for it to come with a stronger pin. However, if you're building an AR15 you should already have an assortment of punches, which you can use with this tool.
