So, as isogamer2009 pinted out, there were a problem with PR's RedDot sight, it was misaligned due to new model of PR (mk1). And I want to say Thanks to isogamer2009 for his feedback, and Thanks to you all for Support!) I've fixed this issue and uploaded new versions, so pleas, download them if you use RedDot sight, or want to use.
Survival Mod v 1.42 (include Real Weapon pack)
Real USCM Weapons pack v1.02 (only weapon parameters and Mk1 PR)
