KAK Industry AR-15 MIL-SPEC Standard Carbine Endplate
Ratings & Reviews
by Ed -
inner diameter very tight ,outer diameter to large its bigger then the castle nut and it hit the charging handle it sits up so high.
I've used probably about 20 of these over several years. It does the job just fine, I've never had an issue with fitment...indistinguishable from any other standard endplate I've used.
