Aero Precision APRH100017C CarbineAR15/AR10 Stainless Steel 9.80"

The Aero Precision APRH100017C stainless steel carbine buffer spring is a core recoil management component for AR15 and AR10 platform rifles. At 9.80 inches, this spring is engineered to work within carbine-length systems, managing the reciprocating mass of your bolt carrier group and helping regulate cyclic rate during firing. Built from stainless steel, it resists corrosion and wear better than phosphate-coated alternatives, making it a solid choice if you run your rifle hard or in harsh conditions.

Buffer springs are often overlooked, but they're part of the tuning equation—especially if you're running a suppressor, short-barreled upper, or experimenting with different bolt carrier weights or ammunition. Aero Precision manufactures this component in the USA, and the stainless construction means it'll outlast springs that degrade over time. Whether you're building a new carbine or refreshing an aging rifle's internals, this is a straightforward, no-frills replacement or upgrade.

Since Aero Precision also produces the buffer tubes and lower receivers that house these springs, their components tend to work together reliably. If you're swapping uppers, tuning recoil feel, or just maintaining your rifle, a quality buffer spring is maintenance you can count on.

Frequently Asked Questions

Will this buffer spring work in my AR15 or AR10?

This 9.80" carbine buffer spring is designed for AR15 and AR10 rifles equipped with carbine-length buffer tubes. Verify your rifle uses a carbine-length system—some uppers and builds use rifle-length or pistol-length tubes, which require different spring lengths.

How is stainless steel better than standard buffer springs?

Stainless steel resists rust and corrosion better than phosphate-coated or parkerized springs, especially in wet or humid conditions. It tends to maintain its properties longer under repeated cycling.

Is this a direct replacement for my current buffer spring?

If your rifle uses a 9.80" carbine-length buffer spring, this Aero Precision unit serves as a straightforward replacement. Check your current setup to confirm the length matches.

Do I need any tools to install this?

Installation requires disassembly of your buffer tube and is typically a simple swap. If you're unfamiliar with AR platform maintenance, consult an armorer or refer to the rifle manufacturer's manual for guidance.
