                        The ALG Forged QD Sling Swivel (FSS) is a lightweight yet heavy-duty sling swivel option.

This process allows the FSS to be strong enough to withstand...

Sear geometry has not been changed from standard so the high reliability that the stock trigger is known for is unchanged. Trigger and hammer are made from true 8620 alloy steel military specification castings, correctly carburized, quenched and tempered for...

Built by the Tier One supplier for military contractors of the M4 Carbine, these are the superior buffer tubes that military and law enforcement officers entrust...
