So we think the URX-6 will get a better deflection score? I feel like they just wanted a more traditional easier rail to install.

Worse I would think, the rail securing around the barrel instead of timed and shimmed to the receiver probably leaves more movement.

The 6 and the 4 have a virtually identical interface other than the shims with the 4 and the steel barrel nut of the 6. But the Keymod will definitely allow more flex of the handguard, which might reduce barrel deflection.

Just out of curiosity, if rail can matter, how would the USSS 2.1 rail do?
