Dynamic Action Buffer – Type B
 
The Type B Buffer gives a much heavier felt recoil when firing the GDR15 or GDR416 and is 4 times the weight of the stock buffer at 120g
 
Included is an 20 pound Buffer spring which keeps the cycling and response rate similar to that of the stock GDR15 / GDR416.
 
PLEASE NOTE - NOT TO BE USED WITH THE STEEL BCG SET
