Great Lakes Tactical (GLT) makes a SOCOM 16 adapter that allows a shooter to attach any common 5/8-24 muzzle device, such as a sound suppressor, without the need to to swap out the factory front sight or gas plug.

Although the factory gas plug works with the adapter, GLT also makes a replacement plug that matches the look of the adapter. Both products are machined from heat treated stainless steel.  The adapter is $169.99, while the plug is $49.99.

I had a chance to see the adapter and plug two weeks ago when visiting the Cleveland, OH area where GLT is based.  The parts looked well machined and matched the look of the SOCOM 16 we had on the range.
