Piston Upper 10.3 Adams Arms XLP

by Stihl, from LA, United States Written on April 20, 2020
The standard buffer helped cycle the rounds correctly in the the gun, I also used the spring that came with the buffer.

I did have an H2 buffer and spring (unknown) in the gun and it would not eject the rounds out at all.
Pros:
  • N/A
Cons:
  • N/A
Would recommend: Yes

Good set for the price

by Vidal Saenz, Verified Owner from TX, United States Written on January 17, 2019
I was building an inexpensive AR so I purchased this set. Acceptable quality for the price. I installed and tested it and have had zero issues. If you are looking for the best, this is not it. If you are looking for an economic and good solution, then this is it.

Works as Designed

by SeaWolf, Verified Owner from FL, United States Written on August 9, 2018
This is a standard weight buffer that works as designed with 16" barrel. Functioned flawlessly in what is a MILSPEC AR-15 build. Tested by standard function check and then fired 100 rounds with no issues. Ordered a second one.

Good value

by Dark Knight, from TX, United States Written on July 13, 2018
So I build quite a few AR's and I like a few spares to speed up the process. This represents good value for money. The shipping was well priced and quick. I would recommend this for your next AR build.

Not a whole lot to say about a spring and buffer. They fit properly, easy to install and seem to be of good quality. Again, I can't say enough good things about Customer Service, they go above and beyond to make sure the customer gets the best price and quality products.

Thanks Optics Planet

  • Good Quality and Fit
Cons:
  • None
Best Used for:
  • ar pistol
  • AR - 15

Simple buffer and spring

by Dano, from VA, United States Written on April 23, 2018
Needed a buffer and spring for a blackout build. Flawless function. What else can I say. It either works or it doesn’t and this one works. Time will tell as to whether it stands up to abuse but I have had zero problems so far.

GUNTEC AR-15 Buffer Spring Set

by L Boogie, Verified Owner from TX, United States Written on December 15, 2017
GUNTEC USA AR-15 Car Buffer Spring Set was as described and proved ideal for my budget build. I must admit that I had some reservations but they were admittedly due to the cost. I was however pleased when it arrived because it appeared to be, simply, a great deal. I would buy again without hesitation.
