Discreet Low Profile Design

Bonded directly into your wooden or synthetic stock, this adapter sits almost flush with the forend, leaving nothing to snag on brush or catch on a rifle slip. At just 0.3oz (9g), you won’t notice it’s there until you need it. The outer rim is designed to sit slightly proud of the stock, so you can find it by feel in low light or when a shot opportunity comes up fast.

Fits Wood And Synthetic Stocks

This adapter works with both solid and hollow rifle stocks, so it suits most hunting rifles. Solid stocks need a 19mm Forstner bit, while hollow polymer stocks use an 18mm hole saw, with the adapter bonded in place using a metal-filled epoxy. It’s a straightforward job for any competent home gunsmith, and our step by step product guide walks you through the whole process. If you’d rather not drill your own stock, any professional gunsmith can fit it for you.

MagnaSwitch™ Attachment System

This adapter turns your rifle stock into a MagnaSwitch™ mounting point, letting you click your bipod or tripod on and off in seconds without tools. Leave your support gear in the pack until you need it, then attach it quickly when the shot is set up. For even more versatility, a second adapter can be fitted closer to the rifle’s balance point, giving you a better mounting position for tripod heads and angled shooting positions.

FAQs

How Do I Install a Gunsmith Adapter Into My Rifle Stock?

The installation of a Gunsmith Adapter involves removing the rifle action from the stock, marking the center point of the stock, and boring a hole to fit the adapter. It is recommended to seek the help of a professional gunsmith if you are not comfortable with the process.

Where Should the Gunsmith Adapter Be Positioned on the Rifle Stock?

The adapter should be centrally positioned on the centerline of the forearm, ensuring it does not obstruct other fittings or come into contact with the barrel. It should have sufficient space to fit and to accept any bedding medium used.

What Drill Bit Should I Use for Boring a Hole in the Rifle Stock?

For solid material stocks, use a 19mm Forstner bit. For hollow stocks, an 18mm Hole Saw works well. If the initial fitting is too tight, a small rotary power tool can be used to enlarge the hole slightly.

How Do I Bond the Adapter to the Stock and Finalize the Installation?

For solid stocks, clean the bored hole with a suitable solvent degreaser and use a small amount of suitable epoxy, such as Devcon 10110 Type-A Plastic-Steel Putty, to bond the adapter in place. For hollow stocks, ensure the epoxy fully surrounds the adapter from the base to the top without reaching the barrel. After the epoxy cures, remove the masking material, clean the area, reassemble the action to the rifle, and check the zero.

As good as advertised

The CGA is exactly as described. My only complaint is my Henry H12 . 357 does not have enough room to drill out the front stock. So still looking for a good solution. Not the parts fault so 5 stars it is

Gunsmith adapter

I like the concept of less bulk on a bipod mounting system on the stock of a hunting rifle.

Simple easy to install, effective and stable

I’ve installed one of these on every one of rifles for 3 years and will continue to use them in the future

Great Products

I bought several bipods and accessories. These are great products. Equally important to me is their customer service. CS is top notch and you can talk to a real person. They also email back when you reach out. Good Company!!

Works well

First time user

Great product. Lightweight and does what I need it to to do. Easy on and off and the adapter is flush mounted. Did I say great product?

Nice clean look!

The magnetic dust plug is a nice touch! Nice price considering what things cost now a days.

Classic adapter

Awesome piece, easy install, very high quality, works perfect, Thanks

Nice addition

Easy to install, but you need the right tools. Put some thought into where to install it on your gun. At the end of the stock or more in the middle for balance on a tripod.

Classic Gunsmith adapter

Easy enough to install, just need a 3/4 forstner bit, epoxy and follow the directions. Installed on 3 different stocks without issues.

Awesome connector

These are great adapters for the bipod. They sit flush with the stock and you forget they are even there until you need them. Great product!

2 port

Bought this with my order, in case I decide to drill out my stock and install it.

Mountain rifle build

This adapter is perfect for my lightweight mountain rifle.

Best adapter to use

I like these so much I drilled a hole in my brand new carbon fiber stock. It's the cleanest, best looking method of adding a magnaswitch adapter to your rifle!

Gunsmith adapters

Love them and easy to install

great little adapter

This is perhaps the third adapter I have installed into my rifles. I prefer them over the one going over the sling stud. They are extremely low profile and fast to use. I keep using these for most of my rifles

All my Guns

I have installed these on all my rifles.Some rifles have two so I can use my big tripod with Davros head

Great adapter addition.

Gunsmith adapter was a step up from the already great classic adapter on my 300 wm. Sleek finish and even more stability.

Versatile

No problem installing on a variety of stocks. Wood,carbon fiber and composites. JB Weld preferred epoxy.

By pods

I have two of your bipods and have the gunsmith adapters on about four other rifles. Good product, my grandson and I use them all the time.

Exactly as advertised!

Gave me a simple low profile opinion to my tripod shooting system along with the Davros head. Also got the classic rifle adapters for the fore end of my rifle to with the javelin bipod. The entire system is simple, quick, and exactly what I needed. Outstanding customer service and support.

The gunsmith adapter is a

The gunsmith adapter is a great idea. I found it a bit difficult to install. My gun stock is basically a synthetic shell filled with foam inside. I drilled through the forend and into the foam deep enough to the foam. I epoxyed the adapeter. But it broke loose after a couple shots at the range. I had to fish the adapter out and it left a large void in the foam. I took foam away until I could see the barrel channel. I drilled and tapped the back of the adapter, inserted a #6 screw. So I have epoxy sticking to the shell of the stock from the barrel channel to the forend and the screw with the adapter embedded in the mass of epoxy. It is very solid now.

Works great. It's tedius to
