Want to know the secret behind getting that stubborn build to finally run? The one that seems like it’ll never cooperate?
Sometimes the answer isn’t another part. It’s controlling where the bolt carrier group wants to go.
This spring leaves your BCG with nowhere else to go but home.
Pistol caliber carbines chambered in 9mm, .40 S&W, .45 ACP, and 10mm are a blast to shoot, but they’re also much harder on an AR-15’s internal components than a traditional gas-operated rifle. An improperly tuned blowback system can slam the action with excessive force, accelerating wear on your lower receiver and fire control components. Adding a suppressor only increases the challenge by driving the action even harder.
That’s where the BSsquirts Extra Power Recoil Spring comes in.
Manufactured from 17-4 stainless steel, the BSS XP spring provides increased preload over a standard carbine spring. That added spring force helps keep the action closed slightly longer, slowing the initial rearward movement of the bolt and promoting a smoother, more controlled cycling impulse.
Pair it with the proper buffer weight, and you’ll reduce unnecessary abuse on your components while helping your blowback PCC operate the way it was meant to.
XP Spring Features:
- 17-4 Stainless Steel
- Optimized for 9MM, 10MM, .40 S&W, .45 ACP, and .308 blowback and AR platforms

- Reduces felt recoil
- Designed only for Carbine Length Stock and pistol kits.
When your bolt has nowhere else to go but home, your build has a better chance to perform like it should.
