RLL use on 7.62x25 upper?

[760guy]

Anyone run a lightning link on a 7.62x25 upper yet? Please share your experience.

What kind of upper. if it is a blow back model, they use 9mm bolts which are full/semi auto and should be just fine.

The DI ones I believe can be had with standard FA carriers, so should be just fine.
