Pricey, but great! - JMac Customs Buffer Tube Adapter for AKM Stamped Receiver

Works awesome on my WBP Jack. Perfect fit - no sanding or filing needed. I've used two other AK buffer tube adapters, Definitive Arms and Rifle Dynamics. This JMAC is the most expensive of the three, but also the best. Super high quality, with excellent machining and finish. And it is also the most solid once mounted. The QD mount cups on either side are a really nice bonus too. Extremely pleased. I'll use these JMAC adapters from now on whenever I want to put an AR buffer tube and stock on an AK.
