Ratings & Reviews
DON'T BUY IT UNLESS YOU ARE WILLING TO DO THE WORK FOR THEM
by AR CLAUDIO -
It does work, but the tube I got has the threads to big all the way to the back, so the buttstock can not slide all the way in. Nothing that a hand file can not do, but then you will need to repaint it. Why go to all the trouble when they're so many option. First and last item from TIGER ROCK for me.
Tiger Rock Buffer Tube Kit
by WWinSanDiego -
Bought this on sale as part of my AR9 build. Since most things for AR9 seem to cost more, wanted this at the sale price point. No issues as previous reviewer since I live in California and I was making it a compliant rifle by putting on a Thordsen stock (not adjustable). Works well!
Plan on buying a different end plate...
by Joseph -
Buffer tube, spring and buffer itself are all good quality and work well. However plan on buying a different end plate, the index tab is really narrow which allows the tube to rotate a decent amount. I swapped the end plate for another i had laying around, which fixed the problem.
Not Good So Far...

I just recieved this set and its not good. The castle nut will not unscrew off the buffer. Either the threads are bad on buffer or castle nut is bad. I was able to unscrew the nut 2 rotations but it's taking off all th finish in buffer and will not go any further. Maybe I got a bad one which happpens... I emailed Primary Arms so will update this review once I have some form of resolution. Hopefully they help make this right. It appears others had success with this product so I'm hopping this is "one off". I was super excited as PA got my order out ASAP even with holidays. BUT this is the last component of my lattest build and not I have to wait:(.
Perfect buffer tube assembly and almost free
by Cory -
I’m not sure if they recently bumped up their quality control or what, but this buffer tube and spring assembly could not be beat for the price. Everything installed and worked as it should. Threads on buffer tube are perfectly machined and allow for 100% buttstock range of travel.
Bargain and Quality
by Christian -
Fit and finish on all the parts are great! The end plate fit perfectly on my Anderson lower and the buffer tube fit perfectly with my Magpul SL Carbine stock, no wiggle at all! The stock collapsed all the way to the first position, just as it should with any other buffer tube. Put some lube or white lithium grease on the buffer spring to quiet it down and it is good to go! Be advised, these parts are made in China.

I installed the buffer tube with no issues. However when I installed the stock there was a whole lot of slop. The stock wiggles way too much. Last Tiger Rock product for me. Made in China.
I like it.

Was a little skeptical of this after reading reviews. Decided to order anyways over Black Friday when it was on sale.
<br>All in all I did not have any issues like other reviewers had. Maybe their QC isn't good and some bad ones got out? I don't know but mine worked great on my recent build. Can't really comment on long term durability and such but the fit and finish of the tube itself was great. It looks a lot nicer than my other milspec tubes. It is a true black, almost like it was painted?
<br>Not sure but for now I am happy for my aero lower and Magpul ctr stock fits perfect.
Mine doesn't fit!
by Frank -
The buffer tube has serious fit issues for me. It interferes with the upper closing. Back it out and there's not enough on the lip of the buffer retainer pin.
<br>I had never even heard of buffer tubes having dimension problems.
<br>No wonder this is on sale.
Budget product, Quality meets expectations.

I got this on a flash sale for $12 and didn't even bother reading reviews. Upon opening the products, there was no evidence that they were cheaply made. They installed just like they should and my Magpul MOE stock fits snuggly and operates fine. Thanks for saving me a significant amount of money on my build!
