Machining is very good. Few if any tool marks. EXO finish is even and well applied. Bolt functions flawlessly. I started with one shot to check weapon & safety, Flawless! 4 rounds for accuracy and function and sighting in. Flawless! 5 rounds accuracy check and function check. FLAWLESS!GREAT PRODUCT WILL BUY AGAIN !

Failzero Exo M16/4 BCG (No Hammer)
by KJR92
Shipping was fast as always. BCG was for a 10.5 AR pistol built. Paired the Failzero with Vltor A5 buffer kit and a Geissele S3G. Ran 800 rounds without lube from Tula to MFS to brass without any issue. Not even cleaning the BCG yet. It will be good for another 1000 rounds before wipe down. Very happy with the purchase. Excellent service from PA.
FZ BCG
by David Phillips
This is my 2nd FZ bcg and it doesn't disappoint me. Nice slick finish although the shipping box has gotten cheaper. FZ makes an excellent part. Shipping was fast!

This thing is slicker than glass.Satisfied
Slick as hell
by Rob Heine
This thing is slippery. Perfect coating. Fires and cycles flawlessly. Perfect staking, with the little bit of oil in my gun, reduced recharge noise and resistence.
