BENELLI M4 BOLT ASSIST DEVICE MOD 1

NO OFFERS, NO TRADES!! 

Made from spring steel that has been post production cycle heat treated to give the correct amount of spring tension as well as min 500.000 cycle longevity.

Zinc plated and then cerakoted graphite black.
We also incorporated an over travel tab on the one end as with our T&E we saw this as a defect.
Mod 1 is smooth surface.

These will work with all Benelli M4 clones but not with aftermarket aluminum handguard.
A small amount of plastic may have to be removed from the handguard if too tight.
