SILENCERCO AC22 FIXED BARREL SPACER

The SilencerCo AC22 Fixed Barrel Spacer is an essential internal component designed to expand the versatility of your handgun suppressors by allowing them to function safely on fixed-barrel firearms.

Key Benefits & Functionality

• Converts Pistol Cans for Fixed Barrels: Effectively "disables" the movement in the Nielsen device (booster assembly). By replacing the booster spring with this rigid spacer, you prevent the suppressor from reciprocating, which is critical for proper operation on non-tilting barrels.
• Essential for PCCs & Subguns: Perfect for shooters who want to run their pistol suppressors on Pistol Caliber Carbines (PCCs), submachine guns, or rifles.
• Prevents Internal Damage: Using a standard booster spring on a fixed-barrel host can lead to excessive wear or damage to the piston and suppressor internals; this spacer provides the necessary rigid interface to ensure long-term reliability.
• Easy "Drop-In" Installation: Switch between handgun and carbine configurations in minutes. Simply remove the booster spring and slide the AC22 spacer over your piston.

Premium Construction

• High-Strength Material: Meticulously crafted from 17-4 stainless steel, a material renowned for its extreme durability and corrosion resistance.
• Heat-Treated Finish: The spacer undergoes specialized heat treatment to increase hardness and wear resistance, ensuring it can withstand the high pressures and temperatures of tens of thousands of rounds.
• Precision Engineered: Manufactured to SilencerCo’s exact specifications to maintain perfect suppressor alignment and consistent point-of-impact.
