Maxim Defense SCW H3 4.85 oz. - Buffer and Spring

When your AR-15 is running at its most aggressive, the heaviest buffer in the lineup brings it under control. The Maxim Defense SCW H3 Buffer and Spring delivers 4.85 oz. of mass for maximum bolt carrier deceleration on the hardest-running suppressed, short-barreled, and over-gassed builds.

The Maxim Defense SCW H3 Buffer and Spring is a 4.85 oz. extra-heavy buffer and spring assembly designed to enhance Maxim Defense SCW stock and pistol brace systems on the AR-15 platform.

As the heaviest weight in the Maxim Defense SCW buffer lineup, the H3 is purpose-built for the most demanding cycling conditions. Heavily over-gassed barrels, dedicated suppressor hosts running full-time cans, and short-barreled builds with aggressive port sizes all benefit from the maximum deceleration the 4.85 oz. weight provides. The result is dramatically reduced bolt carrier speed, less mechanical stress on your receiver and buffer tube, and a shooting impulse that feels far more controlled than lighter buffer options can deliver.

• Type: Buffer and Spring Assembly
• Buffer Weight: 4.85 oz. (H3)
• Platform: AR-15
• Includes: Buffer and Spring

Designed specifically for Maxim Defense SCW stock and pistol brace systems on the AR-15 platform. The H3 weight is best suited for dedicated suppressor hosts, heavily over-gassed short-barreled rifles, and .300 Blackout or 5.56 NATO builds with aggressive gas port sizing. Ensure your gas system produces enough pressure to reliably cycle this heavy buffer.

At 4.85 oz., the H3 buffer is paired with a matched spring calibrated to balance the extra mass, preventing short-stroking while still delivering the maximum bolt carrier deceleration the SCW system can provide.

Ideal for dedicated suppressor hosts, full-time suppressed SBRs, and AR-15 builds where lighter buffer weights have failed to adequately control bolt carrier velocity and component wear.
