I would like to speak on behalf of CJ and his company. While I didn't purchase these particular items from him, he did make us (150) custom rails for our Starfire gear so we could make the switch over to quickplug matches. Very professional, listens to his customers, and makes a high quality product. Looking forward to working with him for years to come.
I'd also like to give a shout out to Brian Craig and his company, CraigCo, for making us custom backer plates for the rails CJ made for us. The tolerances were dead on for mounting everything together and couldn't be happier with the end product.
Both these companies are folks you want to talk to for your custom equipment needs!
