Premium 9mm Bolt
Anyone who has ever built an AR-9 knows that getting it to run is challenging. I did a ton of research before building my AR-9, and I did not see this bolt combo being promoted very much, but I also didn't see any negative reviews. I took a chance on it, and I am happy with my purchase.

LRBHO maybe works
So let’s talk about the elephant in the room. Your LRBHO only works on certain uppers with this bolt. On my set up it doesn’t. Rather frustrating since that’s why I spent more money on the “enhanced bolt”. This set up does run smooth. You can definitely tell the difference with this setup. Recoil is...

jp bolt and silent spring
Works great on my EPC 9. Quiet and smooth action. I used a timney single stage PCC trigger and the barrel and upper receiver are from Aero Precision. I hope this is helpful

Aero EPC build
Flawless!
I built an Aero EPC 9 ( 8.3in)with jp bolt and Scs( 2 steel + 3 tungsten). The only other non aero parts I used was a rise armament 9mm fcg, radiant raptor charging handle, and radian ambi 45 degree safety selector.
This set up ran like a champ, no issues at all. Assembly was a breeze, other than one small issue. Aero epc lower uses set screws ( not pins) to hold down action lever and rear take down dent+ spring. Clever design, no springs flying out when you take the end plate off.
There was a set screw for the bolt action lever but the one for the rear dent was missing, I just ordered off of Amazon, it's a 4-40 x 1/8th set screw.
The jp bolt + scs work very well for this set up with over 1k rounds fmj , hollows, different grains ... no problem. The lrbo works too.

Best Bcg and buffer spring option
If you can afford it, I would highly recommend this captured buffer spring kit. The Bcg is super easy to clean the spring operated flawlessly, it’s super quiet and smooth. This would be the 3rd one I purchased and runs even better on a ar15.
Pros:
- great quality
- Runs great
- Easy clean
Cons:
- Expensive
Would recommend: Yes
Awesome combo
JP SCS and bolt combo worked like a charm straight out the box! Very happy that I chose these for my Aero EPC build. Function perfectly! Really happy I went with the short stroke model. Zero FTF and zero FTE !
Would recommend: Yes

Competition ready
Have 2 sets, used both in my competition builds and they run flawlessly. The scs buffer really dampens the recoil. Buffer is tunable to adjust stroke, but i was able to run both builds 'as is' with both factory and reloaded ammo. Definetly would recomend this set up for those interested in a reliable ar9/pcc build.
Pros:
- None
Cons:
- Pricey but worth every penny
Best Used for:
- Competition & defense
Would recommend: Yes
