Matt Humphries
First time I went there and was thoroughly impressed with the selection and customer service. Extremely friendly and helpful, bought my first AR there and was advised into a solid and affordable platform — these guys definitely know their stuff. Can't wait to go back and start adding items to my AR. Update: Made a trip back to throw some gear on my AR, Ryan was extremely helpful in picking and installing quality components. Ended up leaving with a new-to-me Maxim AR pistol, a Sig 10mm custom works, and a Springfield Prodigy. Super happy with the customer service and the time these guys take out of their busy day to ensure I leave with the best quality and right-for-me firearms and accessories.

Firearm Sales — New & Used
We carry a curated selection of new and used handguns, rifles, and shotguns from trusted manufacturers. As a gun shop in Kalispell, MT, we stock platforms suited to Northwest Montana life — hunting, ranch, home defense, and range use. Our used firearms are evaluated in-house and transferred in full compliance with federal and Montana law. Every dealer sale includes the ATF Form 4473 and a NICS background check, and we walk first-time buyers through each step so the process is clear and comfortable.
FFL Transfers in Kalispell
Buying a firearm online or from an out-of-state seller? We serve as your local FFL for transfers. Provide the seller our FFL information (call or email and we'll send it directly), and once the firearm arrives you complete the Form 4473, pass the NICS check, and take possession. An FFL transfer in Kalispell is straightforward with our shop — standard transfer fees apply, so call 406-260-2311 for current pricing and turnaround.
NFA / SOT Transfers — Suppressors & SBRs
As an FFL with an SOT, we handle NFA transfers including suppressors, short-barreled rifles (SBRs), and short-barreled shotguns via ATF Form 4. NFA items require fingerprint cards, passport photos, and a $200 tax stamp per item, with wait times set by the ATF. We partner with Allen Arms Tactical, a suppressor distributor, to help Flathead Valley shooters source silencers. We do not list NFA pricing online or process NFA sales online — please call or visit the shop to start an NFA or suppressor transfer in the Flathead Valley.
AR-15 Parts & Accessories
AR-15 parts and accessories are our specialty. From complete upper assemblies, handguards, and triggers to barrels, stocks, and optics, we help you select compatible components for a build or an upgrade. If you're a first-time AR buyer, we'll advise you into a solid, affordable platform rather than upselling parts you don't need — that honest guidance is what customers consistently mention in reviews. For AR-15 parts in Montana, our downtown Kalispell counter is the place to start.
Ammunition & Used Firearms
We keep common and hard-to-find calibers in stock — rifle, pistol, and rimfire — for the range and the field. We also buy quality used firearms and accept trades toward new purchases; bring your firearm in for an in-person evaluation, with offers based on condition, make, model, and current market demand. Private-party transfers for Montana residents are handled with the required background check and paperwork.
