May have to go that route. Ideally I would like to find just the barrel. That way I could sell my 18.5" barrel and pistol grip stock to someone who may want to convert their "field" variant into a "tactical" type. I am LEO, so I may have to just go through my agency ... but I want this for a personally owned weapon, not department owned.
The one Cody linked is OK, but I'd like to get the tactical front sight version - that guy had one, but I missed out on buying it.
