I first saw the wood version and at $100 figured I’d just build one. Then they released a poly version and I picked up one each for AR and AK mags. They work great, except the AR had a narrow lip at the base of the case and mine broke off after loading a dozen or so mags over a period of time. I contacted the company and was told they were aware of the problem and had fixed it for the newer model. They asked for pictures of the broken one, they are sending me a new one. Excellent communication and response. And a good product.
