New here and looking for information at ion on this upper. I'm doing a pistol build. Questions I have are:
What are the personal experianves with this uppe or the company as a whole ?
Can anyone tell me if the piston system is adjustable when only the upper is purchased?
What has the accuracy been for those with this upper?
Thank you
