Can this clear the top 1913 pic rail if used with an Inforce WZmL/WMLx if placed on the Fwd most 45deg position of a BCM KMR-A Rail? Expert Answer

No, it will most likely not because this is a low profile keymod rail, but because this is such a specific question we have no real way of answering unless another user specifically has their rifle set up in the exact same configuration.

Great Low Profile M-Lok Rail by Grem, Verified Owner, February 4, 2021
I got this to mount my Inforce light on my AR pistol. I got the small version and I am glad I did. Easy to mount to the fore grip with captive screws. Sits nice and tight and is good quality. A little pricey but I am happy with the purchase.

Product Info for Arisaka Defense Low Profile KeyMod Picatinny Rails

The Arisaka Low Profile Picatinny Rail is a 5 or 3 slot Picatinny rail for KeyMod handguard systems. It offers a reduced height to pull any Picatinny accessories closer to the handguard. The 5 slot model connects with three of BCM's patented reverse threaded KeyMod screws which will spread the increased stress of large Picatinny accessories like bipods or vertical grips over more KeyMod slots. The 3 slot version is useful when less rail space is required.image

The Low Profile Picatinny Rail is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Requires a T15 Torx wrench for installation (not included). BCM KeyMod screws are covered under US Patent 9377274. Made in specialized factories.
