"Magazine Feedlips Wear Tool"

Does this particular tool see a lot of use or does it gather dust on the shelf?:

Never even knew there was a tool, worse case scenario if the mag lips/body goes bad I throw it away.

IIRC it was designed and patented by Picatinny Arsenal. The PMAG snap covers also have this feature, and I can honestly say I've never even considered using it on a magazine. :confused:

I use the half loaded mag and slap upwards on the base plate method. If a round pops out then it's a no go.

Magazines were intended to be diposable. There isn't a whole lot of long-term engineering that goes into a GI mag. If the lips have gotten to the point that a tool is thought to be needed to return them to serviceability I would rather just get rid of the mag. It has already failed. I don't see bending/reshaping aluminum close to its original form as being a solution to that event. They have already failed and I don't think flexing the metal more as reliable.

I believe this is intended more as a Go/No Go gauge.

I think you're right. I couldn't get the link to work earlier but now that I can see it looks like it is a G/NG and is a gauge as opposed to the tool like the one from Brownells.
As another post mentioned, I use 10-12 rounds in the mag and slap the bottom to test.

Hopefully they learned the lessons from the magazine feedlip gauges Colt and Rock Island developed up back in the late '60s. After testing them in 1968, the Army gave up when they found that the gauges couldn't accurately predict whether or not a magazine would actually work.
