I placed an order for a spre upperback on Dec. 21st with Rguns. I knew it would take a while to get in with the huge crapfest that had just started. But I was expecting that and was just buying it at the time to have as an extra. I really expected it to be a few more months before I received it, but low and behold UPS delivered it today. While waiting for it my plans for it have now changed. As soon as panic subsides I am going to build a lower for it and have a second evil black rifle! I bought the TRR15A3 16" Upper with Superbull Diamond Cut Profile Barrel, YHM Long Free Float Diamond QuadRail Handguard, 1:9 Twist Rate for $575.00 + $20.00 shipping. I have to say it seems to be put together very well. Now I need to go put some rounds down range and test it out.
