Aftermarket grip plug for HK Ambi & Navy Style SEF pattern housings. Store extra gear, paperwork, ect.
Please note: These will fit the SP-5 & SP-5K housings IF the housing has the locking slots present to engage the spring (See picture for illustration). HK no longer adds these slots on newer models so please check before ordering. If you are handy with a Dremel tool you can add these slots to your housing.
