Yes this is the last week for the free extended selector tabs. That upgrade alone is about 40.00 if you have someone do it or get the free latch drill 2 holes and crush the rivets. Did one on my pistol build and it took about 8 minutes with the right tools.
Blocks are down to 8.00 each so it would be 32.00. I was doing the buy 3 get 1 free but have not offered that lately. Which one were you looking for?
