PF entry level upper question

[A5BLASTER]

OP. Mark will have that barrel shooting great. If I remember correctly they hand lapp each barrel. I know they do all the chambering. They just use the blanks you get their hard work in that price tag.

You would be hard pressed to build as good a upper for the price.

Edit to add.

Don't forget to ask Mark about the new member discount he gives for a fourm members first purchase from his shop.
