The TMP Wylde556-K Black stainless suppressor is a 3-baffle Kurz design from Texas Machine Parts in 17-4 stainless steel (TMP part no. W556KB). It is rated for .223/5.56 NATO, with a 0.28-inch bore. It measures 5.4 inches long and 1.6 inches in diameter and weighs 13 ounces without the hub, with a black C-Series Cerakote finish on the outside. TMP designed the baffle system to reduce back pressure and backflow, and a 1/2×28 direct thread hub comes in the box. It is the shortest Wylde can, for a 5.56 carbine or short-barreled host where every inch of overall length counts.

Frequently Asked Questions

Can I take it apart to clean it? No. TMP lists the Wylde as not user-serviceable, so it stays sealed.

What is the minimum barrel length? TMP lists a 10.5-inch barrel restriction for this stainless steel model and gives its full-auto rating as Yes (Limited).

Do I need ATF approval to buy this? No. As of October 9, 2026, ATF no longer requires Form 4 approval, registration or a tax stamp for suppressors. It transfers on a Form 4473 with a background check through a Class 3 (SOT) dealer. State and local laws still apply.
