Before-n-After


Colt LE6920

Front sight base attempted by another shop and sold as work from Specialized Armament.
Poorly cut, crudely ground with a bench or hand grinder, and spray painted flat black. NICE.
This exact front sight base will be reworked and turned into an Operator gas system.

SA Operator Gas Block - Colt LE6920

Believe it or not - this is every part in the top photo except for the new stainless steel roll pin.
Yes, that is the exact same gas tube, all cleaned up and ready to go.
Look closely and you can see the taper pins machined into the sight base.
Also note the small blemish (ding) visible in both photos - under side of the barrel in front of the gas block.
After machining and surface grinding, the barrel assy was given a new phosphate finish.
