Quality adapter

Written by Craig on Dec 29th 2023

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.

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...

Outstanding!

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.

Perfect fit.

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.

jmac mod-2 4.5mm adaptor review

Written by Leo on Oct 19th 2021

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.

fits perfect. Replaced the way too short Bulgarian stock with a usable M4 stock. A few more parts ant this CR107 project will be perfect.

Very well made product. Quality fit and finish. Installed easily. Gives my 107 a lot better fit and makes it more comfortable to shoot as well as helps increase accuracy potential.

Great addition to my PSA AK-E. I bought the triangle side folder and instantly wanted an adjustable length of pull once I got it on the range. This adapter is beautifully machined and worked perfectly!

Perfection! Simply put! I work hard for my money and it was well spent on the am mod2 stock adapter! I’ve put it through the ringer! I’ve used the stock to bust doors and windows and the adapter has never budged! It is rock solid! If it can stand up to my training and vigorous abuse it is the real deal! Great product and as far as price you get what you pay for! I’ve broke 2 ctr buttstocks that we’re attached and this adapter as it hasn’t even lost its shine!

GReat!
