Firearm accessory laws differ from state to state and they change often. Please read this page before you order. It is a summary written for our customers, not legal advice.
We sell accessories, not firearms
West Lake Tactical sells firearm accessories, replacement parts, outdoor gear and a small line of automotive parts. We do not sell firearms, frames, receivers or ammunition, and we do not sell items that federal law requires to be transferred through a licensed dealer. No Federal Firearms License is needed to order from us.
Your responsibility
Buyer is responsible for compliance with all federal, state and local laws. By placing an order you confirm that you are at least 18 years old and that the items you order are legal for you to buy, own and use where you live and where the order is delivered.
California: Assembly Bill 1263
California Assembly Bill 1263 (AB 1263) took effect on January 1, 2026. It revised the definition of a firearm accessory in California Civil Code section 3273.50, subdivision (c), and the duties it places on sellers are set out separately in Civil Code section 3273.51, subdivision (e). Those duties are written to apply to a sale or delivery in California or to a California resident, so they can reach an order even where the delivery address itself is outside the state.
What counts as a firearm accessory
As we read section 3273.50(c), the definition has three parts. An item may qualify if it is:
- an attachment or device used with a firearm that is designed, intended or functions to increase the rate of fire, or to increase the speed at which a person can reload a firearm or replace the magazine;
- an attachment or device described in California Penal Code section 30515, subdivision (a), that may render a firearm an assault weapon; or
- a device, tool, kit, part or parts set that is clearly designed and intended for use in manufacturing firearms.
The Penal Code section 30515(a) features include, for rifles, items such as a pistol grip that protrudes conspicuously beneath the action, a thumbhole stock, a folding or telescoping stock, a flash suppressor or a forward pistol grip; for pistols, features such as a threaded barrel, a second handgrip or a shroud that encloses the barrel; and for shotguns, features such as a folding or telescoping stock or a revolving cylinder.
Because the definition is that broad, several kinds of product we list may be subject to these requirements. Parts under Grips and Bipods, Muzzle and Gunsmithing, and Rails and Handguards can fall under the second part. Magazine couplers and magazine base plate extensions can fall under the first part, because they affect reloading or magazine changes. Assembly and armorer tools can fall under the third part. The same section 3273.51(e) requirements are also written to cover a firearm barrel that is not attached to a firearm and a firearm manufacturing machine.
What the law requires of the seller
As we understand section 3273.51(e), a seller of a qualifying item must:
- give the buyer a clear and conspicuous notice covering six categories of unlawful firearm manufacturing. In broad terms the notice addresses manufacturing more than three firearms in a calendar year; manufacturing a firearm with a three-dimensional printer or a CNC milling machine; manufacturing a firearm with the intent of selling or transferring ownership of that firearm to another individual who is not licensed to manufacture firearms; manufacturing a firearm with the intent to complete the sale, loan or transfer without a required background check initiated by a licensed firearms dealer; allowing, facilitating, aiding or abetting the manufacture of a firearm by a person who is legally prohibited from possessing firearms; and manufacturing, or causing the manufacture of, an assault weapon or other firearm California prohibits;
- receive the buyer’s acknowledgment attesting that the buyer received and understands that notice;
- verify the buyer’s proof of age and identity, showing the buyer is 18 or older;
- ensure the shipping instructions list an address that matches the buyer’s identification;
- mark the package with the required wording, Signature and proof of identification of person aged 18 years or older required for delivery.
- have the purchaser present proof of identification and sign for the package personally at delivery. A signature from another adult in the household does not satisfy this.
How we handle California orders
Every order that is placed in California, shipped to California, or placed by a California resident is reviewed by a person before it is fulfilled. If your order contains an item we believe qualifies, we will email you to complete the notice, your acknowledgment and the verification of your age and identity before anything ships, and the parcel will be marked and released for your signature only. If that process cannot be completed, we cancel the order and tell you why. If you have already paid, you receive a full refund.
Magazine capacity and conversion parts
Several states restrict magazines above a set capacity, and some also restrict the parts used to build or extend one. California Penal Code section 32311 addresses large-capacity magazine conversion kits, described as parts of a functioning large-capacity magazine such as the body, spring, follower and floor plate or end plate. Massachusetts General Laws chapter 140, section 121 and New York Penal Law section 265.00(23) each define a large capacity feeding device by round count rather than by part.
We carry magazine base plate extensions, plus-two floor plates and magazine couplers. Items of this kind may be subject to restrictions in California, Massachusetts, New York and other states, and may not be shipped to some of them. We may decline or cancel orders for these items where they are going to a restricted state. Please check what applies at your address before you order, and if you are unsure about a specific part, ask a qualified attorney or your state authority rather than relying on this page.
Other restricted states
Certain items may not be shipped to some states, including but not limited to New Jersey, New York and Massachusetts, and some city or county rules are stricter than the state rule. We cannot track every local ordinance in the country, so please check what applies at your delivery address before you order. If we find that an item cannot lawfully be shipped to you, we will cancel that item and tell you by email. If you have already paid, you receive a full refund for it.
Not legal advice
This page is a plain summary of how we handle restricted orders, written in our own words. It is not legal advice, it is not a substitute for reading the statutes it mentions, and it is not a complete list of every restriction that may apply to you. Laws change. If you are unsure, check with your state or local authority or a qualified attorney before ordering. Questions about a specific item can go through our contact page.
