ATTENTION : The factory recoil rod is not included.
This DPM kit offers 9 Adjustable user settings.
Included are a DPM Buffer Tube, three different in length buffer springs (small) & three different in length external springs in order the user can fine-tune the weapon for his/hers personal standards. The long spring (more coils) is stronger and has a heavier pound rating than the shorter spring.
The Buffer Tube must always be installed when the DPM buffer springs (small) & the three different in length external springs are used.
