FN America Forward Assist Spring

Any shooter of an AR-15 derivate rifle such as the M16 will tell you the Forward Assist Assembly assists in moving the bolt carrier group forward and ensures the bolt is locked into place. When you do a deep clean and maintenance on your AR-15, you'll want to purchase an ample supply of these FN America springs just in case.

Features:

• Type: AR-15 Mil-Spec

As any high-volume or competition shooter of an AR-15 style rifle will tell you, whatever moving parts your rifle has will need maintenance over time.  FN America understands this better than most and offers various replacement components to keep your rifle at an optimum performance level.
