Stealth™ Recoil Spring SRS™-C Gen 4 (ARM253-C) — 3.3 oz Equivalent

The SRS-C Gen 4 is a simple upgrade with a big payoff: it replaces your standard AR-15 buffer and spring with one captured, self-contained assembly. The goal is straightforward: smoother cycling, less spring noise in the tube, and a more consistent feel from shot to shot.

Why people choose the SRS-C

• Drop-in replacement for a standard buffer and spring
• Captured design helps reduce the typical spring “twang”
• Multi-stage system designed to smooth the recoil cycle
• Easy handling during maintenance since the spring stays contained
• Made in the USA

Specifications

Compatibility and fitment

• Designed for AR-15 platforms using a carbine-length buffer tube
• Most bolt carriers work, but some with a rear opening under 0.60 inches may not function properly
• Can be installed with or without a buffer retainer (based on your setup and preference)

What’s included

• 1 complete SRS-C Gen 4 captured recoil assembly

Installation notes

• Orientation matters: the polymer bumper faces the rear of the firearm and the weight faces the bolt carrier
• If you are tuning a rifle that already runs reliably, change one variable at a time so you can clearly see what improved

FAQ

Is this a drop-in replacement for my buffer and spring?

Yes. The SRS-C Gen 4 is designed to replace a traditional buffer and spring with a single captured assembly.

What does “3.3 oz equivalent” mean?

It refers to the buffer-weight class the system is designed to match in function. The complete captured unit weighs more as a full assembly.

Will it fit my buffer tube?

It is intended for AR-15 platforms that use a carbine-length buffer tube. If your setup uses a proprietary or non-standard tube, confirm fitment before ordering.

Do I need to keep the buffer retainer?

Not necessarily. Many builds run it with or without a buffer retainer. Choose what fits your lower and how you like to service the rifle.

Are there bolt carrier compatibility limitations?

Most carriers have a rear opening over 0.60 inches, but some under 0.60 inches may not function with the SRS system. Measuring the rear opening is the quickest way to confirm.

What’s different about Gen 4?

Gen 4 is the current iteration with updated internal design details intended to improve durability and consistency compared to earlier versions.
