Works perfect looks great
this gives you the look of the original moderator but with the required length to meet regulations, pre drilled for easy pin and weld.
Supper fast shipping. Extremely pleased with the XM-177 flash hider. Will definitely order more parts soon.
Perfect fit and finish, moderates the flash quite well on my SBR. Good product, worth the wait for USPS to finally get it to me.
finish was evenly coated, even got the pin to "pin" it.
