Buy upper and lower separately?

[LoveAR]

Is it ok to buy a BCM upper and lower separately? Will they still fit together as tightly as a complete BCM rifle?

[Kenneth]

Yes. You can buy just about any lower and upper from reputable companies and they will all work.

AR's are not handfitted and assembled. They are designed to be interchangeable. A simple use of the Google search feature would have revealed this info.
