Heckler & Koch MR308 Hook Wrench

Available from stock with us.

The Heckler & Koch spanner for the MR308 / HK417 is a must for anyone who wants to work on their Heckler & Koch themselves or install a folding stock adapter. Since HK uses a stronger buffer tube / receiver extension on its large self-loader, standard AR tools do not fit the installed castle nut that holds the stock parts to the housing.

Product details:

Material: Steel, forged
Surface: Powder coating
for diameters of 34-36mm
