Can you ship my firearm direct to me?
No, all firearms must be transferred to you at our store. Background checks and paperwork must be completed per law.
What is an FFL.?
An "FFL." is a Federal Firearm License. All firearms sold to individuals must be transferred through a Form 4473 and proper background checks, performed in accordance with state and federal laws. Only a business that holds an FFL. can process a firearms transfer. We ship to FFL holders all over the country, where you can pick up your firearm and complete your transaction.

Firearm transfers for both long guns and hand guns cost $35 per firearm. We are required to collect sales tax on the purchase price of the firearm from the seller.

WIn addition we can order in other brand of suppressors or Class III items for our customers. Transfer fees on all NFA items are $60 per item. These items are shipped to your FFL/SOT only.
Will your upper fit my AR15 lower?
Our AR15 uppers are designed to fit all AR15 standard mil-spec lowers. Note: Some poly lowers are extra tight and require a bit of working in order to fit any companies uppers.
Do you test fire your uppers?
All uppers are test fired prior to leaving our facility. We inspect and test fire every unit we make to be sure it cycles and performs well. In the event you have any problems with your new upper cycling with your AR15 lower, please contact us at 425-530-0837 so that we can assist you.
Should I lubricate my bolt and upper prior to firing?
We highly recommend lubrication to the bolt prior to firing. Running your upper a bit "wet" during break in is always a good idea.

Though many bolts can be run dry without damage, they are designed to be lubricated with gun oil before firing.
Your box says to use new ammo in your uppers, can I run reloads or military surplus?
While many people run reloads or military surplus through their firearms, we recommend factory new ammunition for best consistency and performance. It is impossible for us to anticipate loads, pressures and performance on reloaded ammo. Military surplus can be corrosive and inconsistent, especially in primer depth settings. This is why we recommend factory new ammo for best performance.

If you run surplus ammo, make sure you clean your barrel each time you shoot it and use a neutralizing cleaner.
What are the pros and cons of stainless versus mag phosphate finishes?
Stainless steel by nature is easier to keep up, smudges and light wear can be polished out to keep your barrel looking brand new. Mag phos is a great finish but is more prone to scratching. Stainless is shiny, mag phosphate is black.
What does HBAR stand for?
HBAR stands for "heavy" barrel and means that your barrel has a thicker profile than an M4 barrel.
What is an M4 barrel?
An M4 barrel has a cut out for an M203 grenade launcher. It is a bit lighter than other barrels since there is less material where the profile diameter is thinner for the launcher to attach.
Legal compliance?
It is incumbent upon you to confirm that your firearms purchase and any firearm parts, magazines and ammo you purchase are in compliance with your local, state and federal law.
Is there sales tax on Washington purchases?
We are required to charge sales tax on Washington purchases and on incoming transfers of firearms based on the purchase price of the firearm.
My state requires my muzzle device to be "pinned and welded" to the barrell, can you do this.
Yes, we offer "pinning and welding" services as an add on option to most upper units we sell. Call or email us for pricing if you don't see it offered on your selection.
Do you manufacture your uppers?
We currently manufacture most of our own parts for the AR-15 platform and those we don't manufacture in house are machined for us in one of our vendor machine shops to our design and specification or mil spec.

We worked hard to provide the best the industry has to offer in order to assemble a quality, high end product for you. All of our upper units are assembled at our 8,000 sq foot facility in Friday Harbor, Washington and test fired prior to shipping.

How Do I Brighten the Hardened Arms Logo On My Upper?
Gun oil and residue can darken the place where the engraver has etched the anodized finish. Remove the gun oil residue and the white logo will brighten up. Just take a cotton swab and a bit of Goo Be Gone and give it a gentle cleaning and then let the Goo Be Gone dry and the engraving should look like new.
