I have an extra cheap 18" mid length Grendel barrel that I don't have a plan for and I've been wanted to try a Grendel sbr. I'm planning to get the 18" cut down to 12.5" or so and have the gas port opened up.
Now, I know this is not a recommended set-up, but I want to give it a shot anyway as something to mess around with. I'll be planning to shoot it suppressed, and plan on throwing an adjustable gas block on it. I'm pretty confident I can get it to run ok suppressed.
Even though the main point is to have it for shooting with a can, I figure I might as well try to get it to run unsuppressed with the gas block opened up more in case I want to burn up some Wolf from a short package . The issue is that I don't really know what size I should have gas port drilled to. I'd like to open up to a size that should definitely work, but I don't want to go totally crazy with the size. Right now I'm thinking 0.100 should work, but I'm wondering if anybody has tried this before, or maybe has insight as to how I could calculate the size more scientifically that my semi-educated guess about it.
Thanks.
