Sledgehammer 2013: Chad's KelTec RFB 24" FAILS

Don't mess with it if it ain't broke. That lesson rings loud and clear again in the TNP Sledgehammer Drill with Chad from KelTec running his "competition, 3-gun proven" 24" RFB. It is painful to watch but it's real data and I don't hide it. Chad says its the ejector, extractor, magazine, then too much lube, then the ammo, broken weld then some other stuff I forget. Nope. I think it was simple gas adjustment done improperly [but what do I know!] and we didn't have time to troubleshoot it [especially with TNP 18" RFB running 100% out of box, no lube, no nothing]. Nutnfancy Advice: Don't change your gas system adjustment unless it's NOT functioning. Sounds simple but some forum fans and "real gun guys" seem to think otherwise...I guess to prove coolness and know how. Despite this dismal showing, the RFB out of box is extremely reliable and has good accuracy, so do read too much into it! On the upside this RFB in Chad's hands is accurate and we can tell he HAS practiced lots since 2011!
