[Universal Fit with Elastic Stretch​] Made from high-elasticity fiberglass braid, the 30mm sleeve comfortably fits suppressors with an outer diameter of 28mm to 35mm (approx. 1.1"–1.38"), while the 40mm sleeve covers 38mm to 48mm (approx. 1.5"–1.89"). One SKU replaces multiple rigid sizes [Premium Heat Resistance​] Constructed from high-quality flame-retardant fiberglass, this cover provides excellent thermal protection against the extreme heat generated during rapid or sustained fire.(NOTE: This sleeve can get hot on the outside in high temperatures, so it should be used with a suppressor cover.) [10-Inch Fixed Length – Customizable​] Each sleeve comes in a standard 10-inch length. Simply measure your suppressor's body length, then trim the sleeve with scissors to achieve a perfect fit – no need to order multiple length variants. Works for suppressors from 5 to 10 inches. [Easy Installation & Secure Hold​] The elastic material slides on effortlessly without tools and grips tightly around your suppressor. No straps or fasteners required – the natural tension keeps it securely in place even under heavy recoil. Just measure your suppressor's outer diameter and choose the correct inner diameter. [Lightweight, Durable & Non-Slip​] The fiberglass weave is lightweight and abrasion-resistant, adding minimal weight to your setup. Its textured surface offers a non-slip grip when handling a hot suppressor. Perfect for range days, hunting, tactical training, and competition shooting.
