Product Overview
JP Silent Captured Spring — Reduced-Gas input spring
Make recoil tuning forgiving and stay reliable, smooth operation in builds where recoil mitigation is of the utmost importance. The JP Silent Captured Spring for 22 GT, 6GT 25 GT and all Creedmoor calibers is a replacement, captured spring that keeps the carrier closing force close to stock while significantly lowering the gas force needed to open the bolt — an excellent choice for carefully tuned low recoil supersonic loads, especially on shorter than optimal gas systems
Key benefits
- Easier tuning — Lowers the gas force required to unlock, making suppressed/subsonic loads much more forgiving and reliable.
- Maintains carrier close force — Closes the carrier at 94% of the full‑strength spring, preserving reliable lockup and feeding.
- Reduced gas to open — Requires 18% less gas force to open the bolt versus a full‑strength spring — ideal for reduced‑gas or pistol‑length gas systems.
- Versatile — Works well with 22 GT, 6GT 25 GT and all Creedmoor calibers supersonic ammunition when you need to reduce gas flow to the action.
Technical summary
- Designed for: 22 GT, 6GT 25 GT and all Creedmoor calibers platforms
- Function: Captured, silent spring assembly tuned to reduce required bolt‑opening gas by ~18% while retaining ~94% carrier‑closing force of a full‑strength spring
- Best suited for: Suppressed and builders tuning for reduced gas flow
Installation & notes
- Drop‑in design for straightforward installation; follow standard armorer safety and procedures.
- Tuning: Because this spring reduces the gas needed to open the bolt, verify gas port sizing and buffer/weight choices when switching between supersonic and subsonic loads.
- Compatibility: Intended for low mass and full mass bolt/carrier assemblies — confirm fitment with your specific upper/bolt group before use.
Why choose this spring?
It provides the sweet spot many GT and Creedmoor users need: near‑stock closing reliability with noticeably lower gas demand to unlock. If you’re building a suppressed rifle or trying to make a longer gas system run reliably with heavier bullets, this spring simplifies tuning and improves consistency across loads.
