Most Helpful Positive Review Works as advertised!
If you have a JP SCS buffer I can highly recommend you pick up one of these. For years now I've been running my guns without any retainer pin and while it made it easy to get the buffer out, it was also a pain when the buffer would just fall out if I wasn't careful when I opened up the gun.

Most Helpful Negative Review Spring was all sorts of messed up
The spring was all bent and disproportioned. It seems like the components are good quality but they aren’t up to par with manufacturing I guess. Seems like a pretty obvious quality control issue. If something like this got through I do not recommend.

makes it easy

by Stuart Moore, Verified Owner from TN, United States Written on November 7, 2025
The JP buffer spring can be monotonous with a regular retainer spring to install and remove but, using the JP retainer spring it has become a much simpler process.

works well

by WonTonChickon, Verified Owner from OR, United States Written on October 25, 2025
Got this because I swapped out the budget and spring for a JP SCS set up. It fits. It works.

JP says you really don't need this. Just remove the catch all together. But having this makes me feel better.

Great availability.

by Mryd92, Verified Owner from MI, United States Written on July 6, 2025
I won't have a chance to test this out until my build is complete but I'm certain of the quality. What I appreciated the most was availability on OpticsPlanet where other websites didn't have them all in one place at a decent price.
Pros:
  • reasonable price
Cons:
  • None
Would recommend: Yes

Great Product

by Kenneth Hundt, Verified Owner from IN, United States Written on February 6, 2025
These work a 100% better then stock buffer retaining pins if you use the JP Buffer System. Buy them and try these retaining pins, you will not be disappointed. I am a product snob and if does not work 100% then I will not use it. They are great.
Pros:
  • Everything
Cons:
  • None
Best Used for:
  • JP Buffer assembly
Would recommend: Yes

Does the job it is designed for

by maiti, Verified Owner from LA, United States Written on February 6, 2025
This item is particularly useful for those using JP buffer spring setup. It is designed so that the regular detect pin does not get stuck between weights when removing the buffer spring setup. This design avoids that issue well and mine did not get stuck once.
Pros:
  • Works as designed
Cons:
  • None
Best Used for:
  • JP Buffer assembly
Would recommend: Yes
