| I have a 7.62 SDN6 in jail, the plan was to put it on a 300blk but that upper may have to be delayed awhile. I have an 8" 5.56 upper but have been told the back pressure may be a bit much. Thoughts? |

It's less back pressure than a dedicated 5.56 can.
I would just get an SLR adjustable gas block. I set mine to lock back without a can. With the can, backpressure is minimal. 2 more clicks down, and it's set to the can. I just leave mine at the "without a can" setting. Works perfect. SDN-6 here too |
