I dealer near me bought a Ciener Mini 14 kit for a customer from Brownell's and installed it in the customers Mini 14. The dealer could not make the conversion kit work. The magazine lips were so soft you could bend them with your fingers and the lips would bend while trying to insert the mag into the mag well. The kit it self just seemed to off such poor quality we didn't think we could ever get it to work even with a good mag. The dealer and I both have owned Cierner kits for AR 15 which were made to higher quality than the one Mini 14 kit. Fortunately Brownell's took the kit back and shortly after this Brownell's quit being a dealer for Ciener. It seems to be a crap shoot with Ciener, you may get a good one and you may not. Ciener is noted for have very poor customer service.
