M4 Buffer Tube Adapter

Bought for an Arsenal Sam7r. - The part was machined well, finish was on point, fitment was fantastic.

I was skeptical about buying the stock adapter because of fitment, but everything worked out perfect. I had a PSA AK-101 side folder rifle, and I used this adapter to attach a standard AR15 buffer tube to it. It locks up nice and tight and looks factory, it's very sturdy. I recommend this product to anyone looking to do the same.

This folding adapter works perfect and flawlessly. This is my second one and have to say fit, finish and operation is great. Locks up tight when extended and the hinge is solid.

Very sturdy and it was very easy to install. I like how it extends a little off of the back of the receiver and I also like the qd sling. I would recommend it to anyone looking for an adapter. I had tried to buy some of their grade 2 at receivers to take advantage of the xmas22 code but was only able to add them to the wishlist.

Fit and finish was perfect and looks great!

Outstanding product. Best solution for a stamped Romanian receiver I have seen. Extremely secure and adds to overall stock length.

Whoever designed the milled AK M4 adapter is a genius. That is one of the most intelligently design AK products I’ve ever purchased. Us milled receiver guys don’t have a lot of aftermarket choices, but this product is one of the best on the market! I usually never take the time to contact manufacturers, but I was very impressed! Thank you!

4.5mm pi n Mod 2 adapter is very solid at lock up and release. I am very impressed with the Mod 2 from JMac. Shipped quickly to boot...

Super fast shipping. Product was very easy to install. Very satisfied with product. Only request would be to have a slightly longer top screw. Other than that super solid construction and am very pleased with with the product. 10/10 would recommend

Perfect. Easy installation.

Easy to install once the rivets are removed. Fits perfectly.

The fitment was perfect, flush with the receiver all around. Very well made and designed. Much more comfortable check weld over the OE stock. I am glad I got it and would recommend it to anyone who is considering this adapter.

Absolutely great adapter, fit and finish are excellent. It fits perfect on my Arsenal SLR-101S. I would recommend this adapter if you are considering it.

This is the best adapter on the market to use a buffer tube on an AK platform. I used the adapter on an Arsenal 107 and it fit flawlessly and is extremely well built. This is the only adapter I will recommend.

This HAS to be the strongest M4 Adapter on the market - the design and construction are amazingly strong! It does make the use of irons slightly harder, but doable - and will definitely help in using optics, especially low mounted micros. Great work JC!

EVERYTHING FIT AND WORKED PERFECT!!!

EVERYTHING FIT AND WORKED PERFECT!!! This was a great part that fit solid and no issues.

This is a VERY solid adapter! I’ve had other adapters that worked ok, but none were as solid as and as clean of a setup as JMac’s! I’m very impressed with how beefy this mount is as well. It’s very well machined and has some handy features with the QD mount locations. It was very easy to install so buy with confidence!

My order took 43 minutes to ship, 2 business days to arrive and the product is higher quality than I had expected. I can't say enough good things about my experience here. You won't regret your purchase.

It was super easy to install and locked up nicely. I also enjoyed the fact it doesn’t break the bank. Using in my upcoming rifle course. Probably submit another review after.

Just fit this onto my PSA AK-103. Seems to be well made and high quality so far. Does what it's intended to do and I'm happy with the end result. It did require a decent bit of filing/dremmeling on the part that fits into the rear trunnion. Was way too big to fit at first. Dremmeled the top and bottom with a sanding bit, removing all of the finish and filing down maybe 1/16th of an inch on each side. Ended up fitting snug after that. The pin hole that the 4.5mm pin goes into, is way too small though. I had to put my pin in a drill and spin it around while filing it down to fit. Took A LOT of filing to get the pin to finally fit. It's extremely tight now and ended up bending the pin just a bit. After a decent amount of work, it fits and I know have an AR stock and buffer tube on my AK. The work required isn't an issue for me, as I'm fairly mechanically inclined, but for others, I'd see this being a hassle and possibly requiring a gunsmith. Regardless, It does it's job and looks good as well. Wish it wasn't so expensive, but that's the price we pay for custom parts. 4/5 stars because price is high and did require a significant amount of filing for the right fitment. ---------------------------------------------- Hey Leo, Thank you for the review! The MOD-2 was made to fit Bulgarian/Russian spec 4.5mm trunnions and shouldnt require any fitting on those, you gun however is a PSA and not made to the exact same dimensions. You will likely have to fit any stock adapter to this firearm.

The M4-AK milled receiver stock adapter is a very well made product. JMAC customs has exceeded the expectations for those who own a milled receiver and were left with limited options to change out the stock. This was installed on an Arsenal SLR-95, which only had the upper tang. Since there was no lower tang to remove, The adapter is secured with an upper and lower anchor. I was not able to take full advantage of the JMAC M4-AK adapter to secure the lower anchor to the receiver. This adapter is so well made that even with the shortfalls of my receiver, it did an excellent job of securing the adapter with the bolts provided into both anchors. Thanks again.

Got what was expected.

The M4-AK is lightweight, well designed and easy to install. For those of you with a milled reciever you will spend far more time drilling out the rivets in the tang than you will actually assembling and installing this adapter. It has a flush fit and there is no wiggle between the receiver/M4-AK/buffer tube. This is my first purchase with JMAC and I am impressed with the customer support and quality of these parts. Special thanks to "Doc" at Show and Tuck for the easy to follow install vid.
