The BN39 Primer fuse retrofit kit replaces the fuse base in the BN39s handle, and allows the use of a more reliable primer mechanism and the components in common hand grenade repair kits. The kit accepts the hammer, spring and hammer pivot pin, and a cotter pin and is more drop safe or impact safe, while still being removeable and able to be stored separately. The retrofit kit slightly reduces the volume of the head and should be separated from the load with a cardboard disk to prevent the hammer from being jammed. The pull ring on standard grenade parts kits is not needed and the cotter pin should be tied directly to the pull string and bead.

The S96S rear sight cover was made a while ago when the original S96S released on Defcad, but never implemented. The S96S is a Stoner 63 inspired modular AR15 platform rifle that can be assembled into either the carbine or LMG version of the Stoner 63 with the magazine on top. It includes a handguard and lower receiver skin for a standard AR style firearm without a top mounted magazine and this sight is meant to resemble a S63 top cover on the carbine version while also housing a modern sight. The sight needed for this is a Picatinny Arsenal Ma-tech back up iron sight. This is a prototype part for the unreleased DLC for the S96S and may need fitting or adjustment. It can be made by printers of intermediate to low skill level and it can add a ridiculous retro flair to an AR15 pattern rifle.
