This makes it an essential accessory for shooters running these silencers on platforms that do not provide the rearward energy needed to cycle a conventional piston.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe spacer is precision-machined from \u003cstrong\u003e\u003cspan style=\"background-color: #ffff00;\"\u003e17-4 stainless steel\u003c\/span\u003e\u003c\/strong\u003e and then \u003cstrong\u003eheat-treated\u003c\/strong\u003e for maximum strength, wear resistance, and long-term durability under repeated firing schedules.
