Recce Pro - 13.7" .223 Wylde Complete Upper Receiver

The Recce Pro is the first in our higher end Pro Lineup. 13.7" is about the best Do-It-All length and the Rosco Purebred Barrel is one of the finest on the market. Combine that with a KAK hard chrome 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 SOLGW Nox Flash Hider (16.1" overall length) for an additional $100*

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.
