Having missed the opportunity to get an AA 10.5" upper, I'm finally at the point where I'm looking to build a Grendel SBR.
1. What would be a good length for the Grendel with carbine gas system? 10.5 as done by AA, or some other slightly longer length?
2. Who would be a good source for a Grendel SBR barrel or upper?
3. What size gas port?
Thanks,
