I have a Wilson Combat 300 HAM'R Tactical Fluted AR-15 barrel, its 18" long and was installed on an upper, but never completed. I bought the barrel new with the intention of building my nephew a hog/deer rifle, but he will be getting a 6.5 Creedmoor bolt rifle for Christmas so this project has been cancelled. It retailed from Wilson Combat for $285, I will let it go for $200 plus shipping, which I estimate at about $15. Its like new and unfired. I have decided to stick with my 5.56 rifles so I will not be completing this build with this barrel. I can email or text pics to anyone interested.
