AR-15 Mag gauge.
GREAT. Fast as usual .
This gaude worked great
On brand new magazines the gauge barely goes down between the lips. On two magazines I had that were constantly misfeeding, the top of the gauge went almost all the way down to the feed lips and on the other the top of the gauge went below the feed lips.

Magazine lip gauge
Excellent tool to measure the feed lip closure gap. Indispensable too to ensure reliable magazine lips. I highly recommend one for AR-15/M-16 aluminum magazines.
check specs of GI aluminum mags
I had 16 old well used GI aluminum magazines that were accumulated about 20 years ago during the first "assault weapon" ban. I'd been meaning to rehab them for a very long time and now looking at the next generation of legislation on the horizon thought now would be the time. I disassembled and cleaned all the magazines. I was able to quickly easily and confidently inspect all the feed lips with the Brownells lip gauge and cull the magazines that were out of spec. I replaced all the springs with new springs and the black GI followers with the green anti tilt followers and the base plates with the original Mag Pull Ranger base plates. I refinished all the mags with perma-slik G. Now I have 12 like new GI aluminum mags. Did the Brownells Feed Lip gauge make it possible to do the project? Yes , it was key to insuring reliability. Am I a finacial genius? No I am not. I could have bought 6 Mag Pull magazines for the cost of the gauge and another 6 for the cost of the perma-slik G and been money ahead with 12 brand new Mag Pull magazines. So, if you insist on being old school and run GI aluminum magazines you should have this gauge. Otherwise , just run mag pul magazines. The dust cover serves as a feed lip gauge.
What A Great Product!
Using this and the Brownells feed lip adjusting tool, you can breath new life into those used surplus mags or tune up your current inventory. Simple as can be!
Easy to use field gauge for STANAG magaz
This feedlip gauge is based on the gauge developed by the US Army. The drawing and dimensions for the gauge are available online so you could make your own using the right machine shop. The gauge essentially starts with a large dimension (marked NO GO) which tapers down to a smaller dimension (marked GO). If the smaller dimension (GO) fits through the feedlips but stops before the larger dimension slips through, this magazine is good. If the larger dimension fits right through the feed lips, the lips need to be adjusted down to tighten that clearance. I had two Bravo Company Teflon coated magazines give me issues at the range. They were difficult to load using the MagLula and often did not want to feed the first round into the chamber. The cartridges felt very tight in the magazine. I gauged these mags and found the feedlips to barely allow the GO gauge to slip through. The best magazines I own are a set of dry-film D&H Industries magazines and their feedlips barely allowed the NO GO portion to fit through, so the lips were essentially getting close to being loose. Overall: 4/5 stars, kind of pricey but it is an easy way to check the feed lips on your magazines. I was able to identify the tight magazines and fix them using the Brownells feed lip tool.
