A Ruger American® Generation II Patrol bolt action in 5.56 NATO (also shoots .223 Remington), a 640-class DNT HYDRA-LRF thermal scope, a titanium Inert Haze Dreyse 6 suppressor, a Magpul Hunter American stock, and a Timney trigger set to a crisp 3 lbs — everything a serious varmint and predator hunter needs for coyotes, hogs, and night-time pest control in one ready-to-hunt rifle.

The DNT HYDRA-LRF HS635R pairs a 640x512 sensor with a built-in laser rangefinder and ballistic calculator for confident night shots.
The Inert Haze Dreyse 6 in Grade 5 titanium keeps the whole system quiet, accurate, and neighbor-friendly in pasture and timber country.
Over $5,000 in components (MSRP $5,048+) — complete SBGW package price: $4,048.
Low base magnification and a 640-class sensor make the HS635R ideal for scanning brush lines, hay fields, and timber edges without losing context around the animal.
640-class thermal resolution keeps the image usable deep into digital zoom and pulls detail out of low-contrast, humid-country conditions.
35mm objective with a natural 1.5x base magnification and up to 6x digital zoom — scan wide, then zoom to confirm.
Built-in laser rangefinder and onboard ballistic calculator take the guesswork out of ranging at night.
Read our full field write-up on why the HS635R is our pick for Missouri varmint control.
Designed specifically for 6mm-class bolt guns, the Dreyse 6 delivers superior suppression, precision, and durability. Built with expert craftsmanship, it enhances accuracy and minimizes recoil while maintaining an ultra-quiet shooting experience — exceptional sound reduction with no compromise in bullet velocity or performance. On the range or in the field, reduced muzzle blast keeps your shots on target and follow-ups fast.
6AL4V Grade 5 titanium construction with a DLC / S-Line coating — light on the muzzle, tough in the field.
Full-size bolt-gun can engineered to maximize efficiency — deep sound reduction and less felt recoil with zero velocity loss.
Rated for 223/5.56 bolt actions down to a 10.5" barrel (also 243, 6 ARC, 6 Creedmoor). Not full-auto rated.
NFA ITEM: The Dreyse 6 transfers on an ATF Form 4 through our SOT — no more $200 tax stamp — we walk you through the whole process. The rifle transfers on a Form 4473 via local pickup or shipment to your FFL.
The 5.56 NATO chamber runs both 5.56 NATO and .223 Remington, and the 16.1" barrel's fast 1:8 twist stabilizes everything from light varmint bullets up to heavy 77-grain match loads — so this build has excellent factory ammo support:
Suppressed with the Dreyse 6, full-power supersonic loads stay hearing-friendly at the muzzle — no need for specialty subsonic ammo. Ask us what's on the shelf when you pick up; we're happy to get you zeroed on your preferred load.
One complete package on hand — professionally assembled, fully tested, and ready to go today.
