LANCER SYSTEMS - Magazine Cinch

Excellent fit and stability. May need to “adjust” magwell, if present.

If you're happy with Lancer Mags - quality, toughness, polymer - you'll be happy with this. I bought one coupler to test and see if I like it. Very happy. Ordering another. This will still fit into a single AR mag pouch (Bladetech) and hold 2 mags - so instead of additional pouches, can hold 2 mags per pouch (see photos). They are still easy to load ammo being attached. They seem durable - I dropped today at least 10 times from shoulder height (I'm 6'1") to snow covered, frozen ground, no issues. Will be buying another one.

works perfect, could probably just use one of the pair, but just in case added as instructed

Fits GI Mag very well, only minor drawbacks are one comes unassembled and they are independent which provides slightly less stability when forcefully seating the magazine in the mag well. Once you have the couplers placed on the magazines to ensure sufficient clearances, cinch the screws tightly. Load the mags and practice slamming them home a few times to ensure the mags don’t slip out of position in the couples, which could cause an issue with the extra mag touching the base of your optics or blocking the ejection port/cover and preventing proper seating of the mag. The screws and nuts are steel, so they will take the necessary torque to secure. If I could offer a suggestion to the manufacturer, it would be to change the coupler from parallel to 5-10 degree spread between the tops of the two mags to provide sufficient clearance on all makes/models of AR & SCAR platforms. Of course such a change would mean the couplers would no longer be interchangeable.

If you want to carry an extra mag easily for three gun this is a good way to go. They are designed for Lancers so I can see how they wouldn't work so great with pmags or other mags (go fig as mentioned they weren't designed that way). Carrying and extra 30rd mag makes the weapon heavier and a 3 mag pouch becomes a 2 mag pouch...so personally I'd pick up a set to play with but for most situations I'd take a third mag in the pouch than two hooked together.
