51-t mounts already installed with Rocksett?

[brazos609]

Do the 300 BLK uppers come with the 51-t mounts already installed with Rocksett? I am just asking considering those who will be using sonething other than a late model 762-SD since there is not enough barrel to grab with barrel blocks in a vise.

Yes.

You use a receiver block.

Another alternative is to get an upper from another company....there are a few out there making great quality uppers and you could choose if you wanted a mount or not or if you wanted a mount from a different company they could mount that also. Just a thought
