The Advanced Technology Mil-Spec AR-15 buffer tube kit comes with all that you need to install a stock on your lower receiver. It features a 6-position Mil-Spec buffer tube for your favorite collapsible carbine stock. It includes a carbine buffer and recoil spring and the end plate and locking ring. The buffer tube receiver extension features a lip that extends further into the receiver to reduce carrier tilt and ensure buffer tube alignment. The carbine recoil buffer in this buffer tube assembly is a standard 3 ounces, and when combined with the recoil spring, reliably cycles your BCG. Ensure a secure fit to your lower receiver with the included end plate and lock ring, stake the lock ring down, and never worry about it coming loose. All you need is your favorite carbine stock and your one step closer to finishing your build.

  • 6-position buffer tube compatible with Mil-Spec carbine stocks
  • 1.14” outside diameter
  • Standard carbine buffer weight – 3 oz.

Not Primary arms fault but...

by

As a previous reviewer stated this buffer extension will not allow magpul stocks to lock in the first position. The threads are too long. Not only that but the buffer spring is just gritty in the tube. And finally the buffer is a noisy piece of crap.The only reason I gave this one star is the service here at PA. Not one quality piece in this assembly kit....Oh wait the castle nut wasn't awful. Please save yourself the time and money and buy a different buffer assembly kit.

1st time buyer and not the last! ATI buffer tube k

ATI Mil Spec buffer tube kit fit like a glove. Would buy again for a few more builds.This was my 1st time having to buy from Primary Arms and I couldn't have been more pleased with their service and fast shipping. Items ordered were exactly as described.

Review

everything works great aside from the buffer. Makes noise everytime I pick up my firearm. Luckily have an extra from an old POF. Otherwise, great set for the price

Not much to say, satisfactory milspec tube and parts. Went on smooth and worked as expected. As usual from Primary Arms, fast shipping.

First time customer

by

Parts I ordered to further the construction of my AR15 where received earlier than I expected and everything was correct. I was very pleased with costumer service and the product. In the "notes" section when checking out I asked if I could get some stickers along with my order so I can put on my truck next to my NRA sticker and they sent a nice size bumber sticker and another P.A. Sticker. Will without a doubt be ordering from Primary Arms for my future needs!!

First time buyer

by

Primary arms has a great selection and competitive priceing. The website is easy to navigate,prompt shipping and all around a great buying experiance. Ill be a returning customer for sure. Thanks.

Questionable buffer

by

The buffer rattled and the spring moving inside the tube is noisy. I have not actually shot it to see for sure. May have to upgrade to a heavier buffer.

Diameter OK, length not.

by

This is indeed a mil-spec buffer tube in the sense that it is not angled in the rear, but after installing, most stocks will not be able to fully collapse due to the threads being slightly larger in diameter to the diameter of the tube itself. I'm not able to close any of my Magpul stocks completely with this buffer tube, as the threads will not allow it to lock onto the first locking hole. Get a different one.

Poor inside surface finish

by

Very poor inside surface finish, very rough. Also, my Magpul MOE Fixed Carbine Stock would not fit nice onto this tube without modification.

Very solid

by

Very solid kit and it was easy to install.

High quality buffer tube and heavy duty buffer. Great feel once assembled.

Great service

Stay Away!

Horrible tube. Like other reviewers have stated the threads are too long and will NOT let Magpul stocks collapse to the first position. Tried it with a new Hogue stock and same result. Also, you cannot stake the castle nut as there aren't any notches for staking.

Not Bad

by

This buffer assembly went on to my Anderson lower okay. The threads were a little rougher than expected, but i suppose its possible that could have been my receiver. Also the buffer is a bit noisy. However my Hogue stock slid on nicely and locks in all positions. 4/5 for the noisy buffer and ***potentially*** rough threads.

Chose ATI for my first ever AR build

by

I recently picked up a couple stripped lowers. Never had an AR and wanted one bad! My first build was going very smoothly. Lower parts kit installed. Just needed my reciever extension assembly and stock. Went to my LGS today and picked up this kit. I was done in about 10 minutes including the stock and I changed the grip as well! The ATI kit went together perfectly so I will be a future customer! My first lower is now finished and I'm super happy!

Don't buy

by

As usual very fast shipping from primary arms. As for the buffer tube the fit and finish was so terrible that I decided to not even use this this on my build. The only thing usable was the castle nut and spring.The buffer also rattled alot so I just gave up on this and got a spikes kit which was excellent.
