Finally, a no compromise solution for correctly mounting a bayonet to your 16 in. barrel with carbine length gas system.  The Bayonet Extender - Adapter provides a low profile and lightweight design so you can leave it mounted without issues. To install, simply slide the open end of lug extender over your existing lug, lock-down the two set screws with 1/16 in. (.0625) and 3/32 in. (.09375) Allen wrenches / hex keys (tools not included), then attach bayonet to the new lug as normal. Red Loctite or equivalent is recommended on set-screw threads for permanent mounting.

Don't waste your time with the alternate options out there that are either overly bulky and heavy or force you to lose usable blade length on your bayonet!

The Bayonet Lug Extender - Adapter provides a 1.5 in. extension to correctly mount a bayonet to your carbine with 16 in. barrel and carbine length gas system.
