Simple, useful, strong - Magpul Industries Maglink Magazine Coupler for PMAG AK Magazine

Easy to put together and the way it locks into the ridges on the magazine is very sturdy. Absolutely no wiggle. Spacing between mags is perfect for both AK and AR receivers, though you may have to lower the mag on the right to allow an AR dust cover to open/close or to access the safety on an AK. Time will tell how durable it really is but it appears to be the same strength as all other Magpul products.
