USED factory German HK storage, spare parts holderThis part would be better termed as a thread protector holder or spare parts holder. When the thread protector needs to be removed from the barrel, for cans or muzzle attachments, the thread protector can be stored in the grip cap safely.This grip cap stores one thread protector securely inside you lower. We also use this as a plug to keep NFA paperwork, spare parts, and other goodies securely held in the bottom of the lower grip frame of the Navy style grip housings. A must for those that want to keep your spares handy.
Please note: This grip cap will only fit Navy style or SEF Navy HK housings that have the recessed edge in the bottom of the grip frame to hold the retaining clips in place. Will not fit SEF contoured or USA-made grip frames.
