Reviews & Ratings for JMac Customs Buffer Tube Adapter for AKM Stamped Receiver — 8 reviews — Page 1

Needs to be fitted. There is a hole in the accessory that lets it slide over the nonstandard stock “tang”. If it’s not obvious, it also replaces the pistol grip retention nut. There’s play when you torque down the buffer castle nut, so you need to hold your stock center to the rifle while tightening it.

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.

Awesome solid piece for adding a buffer tube to an AK with a wood stock . Very easy to use and works great !

Best fitting I have used. Rock solid and great upgrade. I like others, this thing does not wiggle itself loose after several mags. Utilizes your grip screw, and butt stock screw. Easy to install, and no crazy modifications needed.

Product was in excellent condition on arrival. All part and pieces where in packaging. It was just the width of the part that actually seats in the frame was to wide. But with some sanding and a flat smooth surface. Take a little material off each side and checking fitment over and over i finally got it to set in there very snug and now it works and looks great! Oh yeah i have one of those Ras47 from Century Arms.

Had a lower quality one that worked loose every hundred rounds. Replaced it with a jmac, This one is solid the way it mounts it’s much nicer. Buy once cry once. Looks good, followed video on the internet and install went smooth. Can’t go wrong.

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.

Installed JMac Customs Buffer Tube Adapter on my Reilly Defense RAK-47. This M4 adapter and grip screw link is a high quality made, beautiful addition to any AK. Careful filing down the rear edges of the tang may be required if you choose to leave it on the trunnion, some builders may opt to remove the tang...however it is not necessary. I got a perfect alignment with minor filing and set screw adjustment. Tang in place, you will be sacrificing some of the tube threads to seat but you preserve the resale value of the receiver and option of other attachments later. I did install a buffer spring and weight, simply using the end of the tang as my buffer retention. Its not a real clean look, I would like to brace the buffer better, I will see first how it performs before ratifying the design.
