Both guns runs perfectly. Never had any problems just don’t play anymore. The T10 has recoil with KWA’s recoil systems and the Krytac is never a bad option with its range. Both guns are 400 FPS and roughly 15-20 RPS. KWA Ronin T10 is $400 for the fact that it was never used in the field. KRYTAC MKII SPR was $400 when I bought it but used fairly in on the field. So $350 is fine. If your TAMPA, FL area pickup is nicer so neither pays shipping fees.
