If you are of the opinion that we do not live in a world of ninety degree angles (it took me a few years to be able to make turns less than 90…), you might be interested in checking out the new mounts released by Arisaka.

Arisaka is pleased to release our new Inline and Offset Picatinny Mounts. The Inline version is available for KeyMod and M-Lok, while the Offset version is available for KeyMod, M-Lok, and the Centurion Arms CMR. Both KeyMod mounts utilize Bravo Company’s Patent Pending Inverted KeyMod Screws.

The Inline Picatinny Mount is designed for rail systems that feature 45 degree attachment interfaces (Arisaka lists the BCM KMR, Geissele SMR MK4 and MK8, Mega Arms MKM/MML/Wedge Lock, and Midwest Industries Generation 3 handguards as options). The mounts are height and adjustable side-to-side which should allow you to place accessories at the 1:30 or 10:30 clock positions.

The Offset Picatinny Mount is a combination of Arisaka’s Offset Scout Mount and a short Picatinny rail section. It is designed for rail systems that do not have 45 degree attachment interfaces and also places accessories at the 1:30 or 10:30 clock positions.

Personally I’m interested in the Offsets solely so I can place some BUIS for use during 3-Gun. I’ve looked at a number of other models, and haven’t found one I’m willing to commit to yet–I like that this one offers a wide degree of lateral adjustment.

You can find them at:

    I kinda want to see an Arisaka brand AR-15 now. Like, with all the Japanese markings and a Wakizashi bayonet.
