Arisaka Defense Weaponlight Body for Surefire M600DF Scout Lights

The Arisaka 18350 Series Light Body is a streamlined replacement body for Surefire Scout Light M600DF weapon lights using different batteries than the stock flashlight. It is a great alternative to the stock body, as this light body is manufactured without the Picatinny mounting interface, making it more low-profile and sitting closer to the handguard when mounted.

Additionally, the 18350 Series Light Body converts the light to use a 18350 or 18650 battery instead of CR123 batteries, reducing the length of the weapon light by up to an inch. This is a great feature for those who want to reduce the overall length of their weapon light setup.

If you’re looking to build a complete light from scratch, the Arisaka M600DF Series Light Body is an excellent starting point. Additional components like tail caps and aftermarket light heads are available here.

Another advantage of the Arisaka 18350 Series Light Body is that it will fit in any aftermarket  Surefire Scout mount, as it retains the mounting holes and square lug interface on the underside of the light body. This is handy for those who already have a Scout mount and don’t want to invest in a new one.

The Arisaka M300/M600 Series Light Body is a top-quality upgrade that can greatly improve the performance of your rifle. Its lightweight and streamlined design, combined with its high compatibility with a variety of mounts and tail caps, make it a versatile and functional addition to any tactical or hunting setup.
