Junk! don’t buy - ODIN Works Ambi Modular Safety for AR-15

Putting together a training rifle for training other people, I thought that adding colored control levers would be easier for novice shooters to recognize. first issue, I could not find one manufacturer that made all the components, charging handle magazine, release, safety, select lever, Bolt release, takedown pins. I settled for ordering the components from two different manufactures accepting that the colors wouldn’t be identical from both manufactures. However, the colors aren’t the same from the same manufacturer. The safety select lever is very stiff compared to the factory. I will be returning it if possible don’t waste your money on this brand.
