Excellent for ar platform rifles; not so much for ak rifles - Bravo Company Mfg M-LOK Compatible Mod 3 Vertical Grip

I bought a pair of these for both my AR-15 carbine and PSA PSAK-47 GF3. Firstly, build quality on this product is excellent, including the M-LOK hardware. Polymer material is thick and durable. Installation is what you expect from a quality M-LOK compatible product — it works! On my AR, it works perfect if you want to use it as a fore grip or as a hand stopper if you use a C-clamp grip. Now on my PSAK-47 that has a standard-length M-LOK lower hand guard, I thought it would be long enough to clear rocking the magazines out and rocking another mag back in — apparently not. I tried the furthest M-LOK rail, the closest rail, pointed the grip angle away from the shooter, and toward the shooter — I just could not easily remove the magazines. Keep in mind, I own several types of magazines: Magpul, bakelite, steel surplus mags, and cheap Korean plastic mags. The hardest to remove with the grip installed were my steel magazines. In a real-world defense scenario, not being able to easily remove your magazine is death. This is a non-issue with the AR mags, which simply fall out from the magwell with a push of a button. So in short, I highly recommend this product for AR platform rifles, and I ONLY recommend this product for AK rifles if you have an EXTENDED M-LOK lower hand guard.
