It sure looks tight and slop-free, but the FN A3G's bottom metal is bedded from the factory. Do I need to have the bottom metal re-bedded in Marinetex?

Thanks...
 
As long as it feeds fine Im sure you wont notice any difference between it being bedded and not. If it just plain wont shoot you could try it and see if it fixes anything, but IMO the bottom metal, unless very poorly inletted, is the least of your accuracy concerns.
 
It feeds slicker than owl shit with the Alpha Type 2 magazine. I am going to bench it this weekend and really check to see if the accuracy was affected at all. I was thinking about long-term durability - I assume the McMillan fiberglass won't compress much, if any?
