After doing some research prior to purchase, we decided not to purchase Ciener’s products because of feedback about his customer service. We purchased CMMG units instead. Apparently, TOO many people complained.
i bought mine through a vendor since I heard so many horror stories about dealing w Cienor directly.
I love the kit for the AR though. Got a few mags at Brownells and good to go. save a ton of money.
I’ve been using a CMMG stainless steel version to great satisfaction and problem free functioning. There is a third company making these, located I think in Huntsville, AL. They make an excellent product but it is not stainless steel. You can order directly from them and save about $30 bucks per unit.
