Swiss Arms-AR Magazine Adapter

Hi CGN,

I'm looking for a few product testers for a magazine well adapter for the Swiss Arms rifles.

It's a small part that clips onto the front of your existing magazine well, and allows you to use modified AR magazines. No nuts and bolts, no gunsmithing, and no modifications to the rifle are required. Installation takes about two seconds.

It will sell as a set, with the part itself, and a piece to be used as a guide for filing the required notch in the magazines. Should come in at a fraction of the price of similar units on the market now.

I've range tested it using Gen 2/3 PMAGs, and will have a more comprehensive test done in the next couple of weeks.

I'll send a few out (for free) to CGNers that would be interested in trying them out and giving me some feedback.

Please email me at alex@gsdesigns.ca if you are available/interested.

I'd be looking for feedback with regards to your opinion on:

-product fitment
-functionality
-durability
-ease of use
-suggested price point

So what on the AR mag do you have to modify for the adapter to work?

Freakin awesome regardless tho!!!!

A small notch needs to be filed into the spine of the magazine at a specific distance from the feed lips:

Yes, as long as the front part of your magwell has approximately the same dimensions as mine. Since they're all built in the same factory, I'd assume they're all the same unless they made some modifications over the years.
 
How critical is the placement and depth of the notch that needs to be filed? I was wondering if a deeper notch provided more "meat" (and therefore a more solid lockup) for the AR mag to latch in.
 
Placement is more important than depth. If the cut is too high, then the mag will sit too low and won't feed properly.

Depth should be 1.5-2mm. Any deeper and you cut through the spine of the mag, and if you go much deeper than that it may interfere with follower movement.

There will be instructions provided.
 
Got mine in the mail today - what a fantastic little device!

I tried 5 of my mags that I previously 'slotted' for the old mag adapter that used to be commonly available - and they all fit, released, and fed dummy rounds perfectly. The 3D printed 'guide' that you included was fantastic idea as well... the old adapter just had a measurement, which could potentially vary from mag to mag. The dimensions from your guide piece exactly matched my mags perfectly, so looks like it's the same!

This is a simple and inexpensive solution... and so far it just WORKS. I'm shocked and pleasantly surprised! I will give it a live-fire test soon and post some results.

Sounds good. Looking forward to hearing how it goes.

By the way, which "old adapter" do you have?
 
Anyone try the Alberta Rifle AT15 mags yet with this adapter yet?
I'm wondering if the 'spine' on the ATRS mags have enough material for the notch that needs to be cut. The Pmag spine seems slightly thicker so this is not an issue.
