Vratná pružina DPM pro Walther PDP 4.5" & 5" Barrel 18 Adustable User Settings

DPM MRS for Walther PDP 4.5″ & 5″    18 settings

This DPM System works with 6 different buffer recoil springs which each one offers different spring force (forces are listed at the end of the description).

The System includes 3 external springs, 6 buffer recoil springs and 1 safety pin.

The longer spring (more coils) is stronger and has a heavier pound rating than the shorter spring.

Forces:

Soft 0.7mm

Short = 8.0 kg/ 17 lbs

Medium = 9 kg/ 20 lbs

Long = 10 kg/ 22 lbs

Hard 0.8mm

Short = 9.0 kg/ 20 lbs

Medium = 10.5 kg/ 23 lbs

Long = 11.5 kg/ 26 lbs

Suggestion: For low power (very soft ammunition) its not essential to use any of the Buffer Springs.     

In that case the System in full open position offers 7 kgs/ 15 lbs total force.

Feel free to try any possible combination of the external and buffer springs to fine tune the pistol function depending the power of the ammunition is used and according to your personal standards.
