Best option for kr103 - JMac Customs Buffer Tube Adapter for AKM Stamped Receiver

This is by far the best buffer tube adapter I've purchased. It fits incredibly tight in my KR103 with absolutely no wobble. So tight that at first, I didn't think it would fit, but it slid in with an appropriate amount of force. At first I was put off because there's only 1 hole to mount the adapter to the rear trunnion, while other adapters utilize both trunnion screws. After seeing how the rear screw secures the adapter, I believe it to be far superior to the trunnion screws, which are usually thin and shallow. A thick screw goes into the rear of the adapter and mounts to the proprietary T nut, effectively securing the adapter. This combined with the trunnion screw seems to join your adapter, trunnion, reciever, and pistol grip together. The assembly feels incredibly solid and I'd wager it's less likely to come loose over time than any other adapter I've seen on the market. Fit and finish are superb. I install buffer tube adapters on all AK's I own aside from a single rifle with wood furniture for novelty purposes. This is the only adapter I'll use with any AKM pattern rifle going forward. This beats out the Rifle Dynamics adapter by a long shot. If you're looking to install a buffer tube adapter on your AK, you're doing yourself a disservice by considering any product other than the JMAC.
