Any help plzplz ?
I'm a midway in tuning my MBX buffer + their yellow combo spring
Shooting factory 124 Sellier&Bellot / 124 STV Scorpio
Gun is 12.5" ADC 9, blowback
And i can't tune it properly !
____
Blue inner spring with second hole (short) + BCG weight removed = Double Feed + FTEject + funny fullauto mode (It's was not funny for a RO)
Blue inner spring with first hole (long) = Double Feed + FTEject
____
Green inner spring with first hole (long) = seems ok, But FTEject 1/100 rounds
____
Red inner spring (long) = Ok, but heavy dot movement to 2 o'clock doubletapping (6 inch from 20 yards)
Red inner spring (short) + 2 coins buffer = Better (faster), but still dot movement to 3 o'clock doubletapping (5 inch from 20 yards)
any ideas, what can i try to make movement flatter?
