After receiving my KAC Rail Cover Panels, these covers fit perfectly on standard Picatinny RIS/RAS handguards. They slide on smoothly and lock in place securely without any wobble, making installation quick and hassle-free. Though it may require a bit of force to install initially (But ensures a snug fit)
Would definitely purchase again!
i bought this to replace carry handle sights on my WE M4,good quality! nothing woobles unlike wem4 sights :)
not fitting well(oring problem maybe),+spring is weak must be changed
)
No way around it, probably got sent one for a gen 4 :(
