Just FYI folks.
When selecting the Adams Arms piston blocks then going to the piston selection incorrect piston lengths for the barrel gas port are not 'x''d as incompatible like happens with gas tubes.
The CMMG piston parts are available in .300 Blackout but not the Adams Arms piston parts. (Not sure if it's supposed to be that way or not).
Installing the non railed Adams Arms piston block doesn't allow for free float handguards to go over it. Again here, I'm not sure if it's because the piston block actually can't be used with a full free float rail or if it's an oversight.
Just wanted to let you all know the observations for any changes you may need to make. If I find any other glitches I'll post them here for you.
Regards to all,

P.S. Thank you VERY much for this last competition. I had a lot of fun designing for it. At times it really did become difficult to create new descriptions - I think I probably wrote about 10,000 words of them :) I think my wife is happy that the competition has ended!
