....YES, LongShot Mfg rails were formerly made under the name Harttool and also sold on ebay under the seller ID of Mold99. The official manufacturer and company name for all our picatinny rails, barrel shrouds, charging handles, mag bumpers and mag release buttons is LongShot Mfg. LLC. Our company website url address is both www.longshotmfg.com AND www.longshotmanufacturing. Both of those url addresses will automatically bring you directly to our LongShot website. These questions keep coming up and I thought that I would personally address it here on the forum. j.
