It will run as it is. No special buffers or springs needed. I run my UCIW stock on an 8" .300 blackout, 7.5" 7.62x39, 12.5" 6.8 and 10" suppressed 5.56 without issues.

Good news! Glad to hear I should be OK. I thought about .300 blackout but I just don't want to mess with another caliber.

I wouldn't bother with special buffers unless you want to run 5.7 or 9mm configurations. It's always good to have an O ring available just in case your having extraction issues. If you need one, PM me and I can mail you one.

I use the 5 coil extractor spring and a H2 on anything less than 10.5", YMMV...

I have heard stories of anything under 10.5 inches being problematic so hearing that this is not the case is good news. Now to decide on a 9 inch or 10 inch hand guard!

You should be fine with stock parts. I am running a 7.5" upper in 5.56. It does throw an awful lot of flame. I think 7.5" might be a little short, but it does look sweet. Currently waiting on an 8" 300 blk barrel I found for $100 here. The 300 blk my buddy has does not throw out near as much flame.
