I have a total of 6 loading blocks forsale. These are all MTM brand. Three are grey, two are red and one is orange. All are in great shape except for one got too close to the furnace and the handle is light melted. Does not mess with the holding of brass at all. These will do most all rifle and pistol. These are two sided. Since they are kinda heavy I'll take 25 shipped for them all or trade for the following: Sig 220, 229 mags Glock 17, 19, 18, 20 and 29 mags Or what ever else Thanks "duck"
