Know Your Mags Are Legal

Division compliance shouldn't be a guess.

Magazine length is one of the few things in this sport you can verify with certainty before you ever leave the house — so verify it.

The 71 Creative USPSA Mag Gauge checks both 141.25mm and 171.25mm magazine lengths, giving you one simple tool for checking your competition mags. Drop the mag into the gauge, confirm it clears, and you have your answer.

No calipers. No math. No wondering whether that new basepad pushed you over the limit.

Why We Made It

Standard metal magazine gauges work — but they're expensive for a tool with one simple job.

We wanted the same straightforward pass-or-fail check without the price tag of a machined metal gauge. So we built one.

It's lightweight, durable, and checks both USPSA magazine gauge lengths in one tool. Keep it on your bench or throw it in your range bag and check your mags whenever something changes.
