The Recce Rack is the Recce Pro with all the extras cut out. BA Hanson 13.7" barrel is the heart of the build, combine that with a AO Precision TMS BCG, Lapped and Bedded Action, And then you have what I believe to be the best Performing upper at this price tier and the next one up.

*Also available with a P&W KAK M58 Flash Hider (16.1" overall length) for an additional $25*

Barrel nut is sequentially torqued down to 50 FT-lbs. Starting at 25, then 35, and then finally 50 FT-lbs to ensure proper mating of the threads. 
 
Barrel is also bedded to the upper receiver with a expanding/hardening compound to ensure perfect fit and reliable accuracy. 
 
If you legit burn out a barrel, like 10,000 -25,000 rounds, and the barrel becomes inaccurate I will rebarrel it for you for free. Good luck.
