Many of you have seen glimpses of Arisaka products in the BCM KMR and Magpul M-Lok threads, as well as some of the various picture threads spread across m4carbine.net, but I’d like to formally introduce everyone to our company and product line, and invite questions, discussion, and feedback. I also want to thank G&R for running this forum and allowing us to contribute.
Arisaka is a design and manufacturing company based out of Apex, NC. The company is run by myself (Will) and my close friend Walter, and we employ several of our family members. All of our products are entirely manufactured in the USA. Additional background details about Arisaka can be found at http://arisakadefense.com/pages/about-us.
Our initial product offering includes a line of light mounts and control accessories for KeyMod, M-Lok, and Centurion CMR handguards. The following is a brief overview of our product line. The majority of the photos are provided by UWone77 (Richdkim on m4c) and Stickman.
Inline Scout Mount - Designed primarily for KeyMod and M-Lok handguards with 45 degree mounting surfaces like the BCM KMR and Geissele MK8, the inline scout mount places M300 and M600 Scout lights very close to the handguard. The mount features three lateral positions for the Scout light, allowing you to tuck it up close to the top Picatinny rail or give more clearance around wider front sights. The base of the Scout light sits 0.200" above the KeyMod or M-Lok mounting surface, so it’s extremely low profile.
Ring Light Mount - Available for KeyMod, M-Lok, and CMR, the ring light mount uses a vertically secured closed ring to clamp a light in place. Two ring sizes can accommodate lights with diameters from 1.00-1.03" and 0.84-0.88".
Finger Stop - Available or KeyMod, M-Lok, and CMR, the finger stop is meant to be placed further forward on the handguard, between your index and middle fingers. It can also be used as a forward hand stop. Several customers have told me that it works for their setup as a rear hand stop, although this wasn’t my original intent when I designed the part.
QD Mount - A low profile QD mount for M-Lok handguards. Not much to be said about it. 
While our current product lineup isn’t very broad, we do have a few new parts in production right now. The first is a minimal vertical grip which will be available for all three handguard interfaces.
Second is a streamlined mini-Scout body which will allow a wider range of front sight compatibility when used with our inline scout mount on handguards like the BCM KMR, KAC URX4, and Geissele MK8. In particular, the mini-Scout body does not include the Picatinny mount wings, which are main clearance issue with Diamondhead and Troy front folding sights. You’ll also be able to “build” your own mini-Scout by using a Malkoff E1/Scout head and Surefire Z68 tailcap. Both these and the vertical grips will hopefully be available by the end of December.
We have a whole list of additional products waiting to go into production, so 2015 should be an exciting year for us. If you have any questions or comments please feel free to post, and you can contact me here on the forums by PM or email - will@arisakadefense.com.
