Reviews & Ratings for J&E Machine Tech A2 Buffer Tube Combo Kit — 10 reviews — Page 1

Works great as a kit, no problem installing it. Fast shipping and good value!

Great kit, comes with everything show on the picture. I have no complains!

This is just a regular buffer tube kit. Nothing fancy. It fits and runs perfectly.

Parts came in good condition fits as expected. Kinda hard to mess up a tube and spring

Good quality kit at a good price. Fit well and great fro a rifle length build.

Bolt was to long.had to cut it off about 3/16. Other than that its great product

I purchased this tube and recoil spring/buffer for a 762 build. After opening the package I noticed that this spring felt very heavy.
I proceeded to finish the build using this spring and buffer tube.
Well I guess you know the outcome, it did not cycle.
After measuring the spring and comparing it to a std mil spec AR15 223/556 I noticed a big difference in the coil spring wire diameter.
It measured .080 mind you , a std AR15 .223/.556 measures .074. It might not seem a lot, (.006) but when you are compressing the spring to a specific length, it matters. It took almost 35% more pressure to collapse the spring to be equal to a .223/.556

I have read other reviews stating this kit works great.
I think this kit had the wrong spring
In my opinion, this spring will only work on a 308
I will contact Optics Planet to see if they will exchange or refund my purchase

I was pleased with what I received. The product is very affordable and I didn't seem to have any cycling issue or malfunctions with my rifle.
I would recommend.
The buffer tube is well machined and simple to install.
I will definitely purchase another for my next build

While the actually Buffer tube is correct, the buffer spring which was included is definitely incorrect, it is ever so over stiff, I can't even imagine it operating with a AR-10 platform, as I could not hardly operate even an oversized charging handle ! This A-2 Buffer tube and spring were specifically marketed as a AR-15 Buffer Tube assembly !
As I have installed the original AR-15 Buffer spring intended for a shorter adjustable Buttstock, at this Time I am unsure if it will function properly being excessively on the weak side being inside of a much longer A-2 Buffer tube !
As this was Marketed for a AR-15 platform, one would believe that it would include a properly functioning spring intended for a 5.56mm, maybe even a choice of spring designed and rated for other Calibers.

As I can't say the Buffer tube itself is not worth having, I can't recommend anybody purchasing an incomplete assembly.

The machined parts are good but the spring is way over sprung. Incorrect spring for the AR-15. also does not include the sling end plate shown in the picture. not that its needed anyways. I replaced the spring with one from another manufacturer and everything worked perfectly. If they provided the correct spring it would be 5 stars.
