050806109902 Convenient “Go/No-Go” gauge lets you quickly and accurately check for correct feed lip gap. Helps ensure reliable feeding and prevent weapon failure caused by feed problems. Simply slip over the back of a suspect magazine and lightly press gauge between magazine feed lips. If the gauge passes through feed lips, either discard that magazine or use the Brownells Magazine Feed Lip Tool (available separately) to bring them back into specs and restore reliable feeds. If the gauge won’t pass through the lips, the gap is too narrow and must be widened. Machined from 4140 chrome-moly steel heat hardened to Rc 50-55 for dimensional stability, plus resistance to wear and corrosion.Delivery time approx. 7-14 days.

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.
