I called MWS and talked to Ian to find a carrier for my build. He told me about his carriers he was selling, I was looking for a cheap carrier and did not want to spend 169. I went by and finally looked at it, I could tell right away why these were 169 vs 120 for a standard carrier. After thinking about it I bought one, finished my build it runs goo and I cleaned it quick, the finish doesnt hold dirt. I just picked up my second one today, can't beat them. Ian also said they were built from Rhino Arms carriers he purchased when they went out of business, I compared they certainly look the same. Nice piece and the price is great !
