Just in and ready for the season 🦃

We’ve got Black River “Lights Out” turkey loads hitting the shelves—just in time to get geared up. If you’re looking to tighten up your setup before opening day, this is a solid option to check out.

Looking for a speaker that can actually keep up with you? 🔊

We’ve got a few DemerBox Speaker units on the shelf that deserve a good home.

These aren’t your average Bluetooth speakers, they’re built in a super tough, waterproof case, designed to handle the outdoors, job sites, range days, and just about anything you throw at them. Long battery life, loud/clear sound, and built to last.

If you’ve been thinking about upgrading your portable audio setup, now’s a great time to stop in and check one out!

Just wrapped up a custom project we’re pretty excited about!

This Browning Buck Mark came through the shop for a Cerakote treatment in a Kryptek camo pattern and it turned out sharp. The detail in this pattern really pops on the Buck Mark platform and gives it a completely new look while still keeping that clean, functional feel.

Something new is landing TOODAY👀

We’ll have the Disrupter from Partisan Triggers hitting the shelves. Designed to fit the standard AR platform, this is one to keep on your radar if you’ve been following the latest in trigger design.

Stop in and take a look—we’ll have it ready.

**UPDATE** Triggers are here!!!
