Rugged Suppressors 3 Lug Adapter Features The Rugged Suppressors 3 Lug Adapter is machined from steel to precise dimensional tolerances for long-term reliability and durable construction through repeated suppressor attachment cycles on HK-pattern 9mm platforms. The patented Go/No Go Gauge provides immediate confirmation that the suppressor is properly attached before firing eliminating the guesswork and potential safety concerns associated with improperly seated suppressor mounts. The 1/2x36 TPI thread pattern is machined to 9mm HK spec for a direct precise fit on compatible HK-pattern hosts without requiring additional adapters. The black finish provides corrosion resistance and a low-profile appearance consistent with standard suppressor accessory equipment. Compatible and used in conjunction with Rugged Suppressors 3 Lug Mount the adapter integrates seamlessly into existing Rugged suppressor configurations without additional hardware. Precision manufacturing and durable steel construction ensure years of reliable service across sustained suppressor use.
