Must have for 9mm pcc

by -

Functions flawlessly in my 7.5" build with precision defense bcg and stern defense adapter with glock mags. Running standard carbine spring and runs great!

Extar Ep9


Ordered for my PDW carry firearm Extar Ep9mm works flawlessly no hiccups or bad round feeds definitely feel a lot less recoil compared to stock buffer tube

Works like a charm

This buffer runs very well with a standard AR-15 carbine buffer tube and spring.
