NEW CHRONY-TESTING IN PROGRESS
We're in the process of doing updated chrony tests for many of our custom performance parts. The first of these was recently completed with a 1377 upgraded with our CUP-SEAL VALVE & PISTON KIT. The first test was using our .038" WD HAMMER SPRING, the second with OUR .042" WD HAMMER SPRING and the third with our .038" WD HAMMER SPRING and 13XX MAGNUM ADJUSTER. The results of these tests will be quite shocking to many of you but confirm what we've been saying for many years, that more hammer spring force doesn't always produce more power. There's a "sweet spot" where you can get a lot more power with less hammer spring force if you use just the right hammer spring and precise amount of pre-load tension. This info is posted in the TECHNICAL INFO category of the navigation bar above and will also be updated in the related parts listings.
MAGNUM AIRPOWER & MAGNUM FIREPOWER UPDATE
In 2020 the corporate registration for this business was amended to change the name to Magnum Gunworks, LLC. Magnum Airpower became the airgun division of Magnum Gunworks, LLC along with the launch of Magnum Firepower which is our firearm parts division. The pandemic caused major delays for Magnum Firepower but it is still in development. We currently only list firearm parts and accessories on GunBroker.com. We are sold-out of everything on Gun Broker at the moment but plan to have listings up again in the near future as well as adding the Magnum Firepower category back to our online store.
IMPORTANT UPDATE ABOUT OUR CUSTOM 13XX VALVES & PISTONS
Our custom 13XX valves require a shorter 3/8" mounting screw for the front of the trigger-frame in order to avoid damaging the valve cap. Both the factory 7/16" screw and the screw included in our 13XX screw kits are too long for the custom valves, when tightened all the way down they create an internal bulge near the valve-check causing the valve to not hold air. A 3/8" socket cap screw is included with our 13XX valve and piston kits. Some older trigger frames with the die-cast metal trigger covers are thick enough that the 7/16" screws work fine, the newer frames with the 3-screw plastic cover are not generally thick enough and allow the screw to bottom-out, if forced to go in deeper that's when the damage occurs. The Delrin base of our custom pistons will bulge if over-tightened, the original version would tend to bind in the tube in this case, these are now tapered more to eliminate this issue. If you ship your older base to us we will taper it for you and ship it back free of charge, email if you need our address.
SHIPPING COST COMPLAINTS - PLEASE READ !!!
You must select First-Class Package Service for the lowest domestic and international shipping rates. A large number of customers have complained about high shipping charges not realizing the USPS automatically selects Priority or Priority Express for you when you start your order, you have to select First-Class Service to get a lower price. We have no control over the process, PayPal manages the cart and determines package size and weight for each order, then the USPS calculates the shipping rate. The only part we play is setting the weight and size of each item we have listed, then the cart estimates the package size and weight for the complete order. Packages over a certain weight can only be shipped Priority or Priority Express.
Please read our TUBE DEFECTS page in the TECHNICAL INFO link above for details about 22XX tubes that may not be safe for bulk-fill, PCP or HPA conversion.
World-wide shipping options available at checkout. Complete airguns, stocks, pistol trigger groups, sights and scopes will not be shipped outside the US and US territories. For US customers, if airguns are considered to be firearms in your state or city we will not ship complete airguns to you.
PayPal is the only payment method currently accepted. You don't need a PayPal account to pay by credit or debit card, you can use PayPal to checkout as a guest.
SALES, SHIPPING, RETURNS & LEGALITIES
You must be 18 years or older to purchase guns and parts.
All parts and guns are well packaged and shipped as quickly as possible. Due to the complete incompetence and unreliability of the USPS we are not responsible for any delays in shipping beyond that. We do not give discounts or refunds for late packages. We will re-ship or refund lost orders but don't consider a package lost until the USPS has no idea where it is and it hasn't scanned for at least three full weeks. All shipments include tracking. All orders will be shipped in 1-5 business days unless otherwise noted in our NEWS section above. If you choose Priority or other "expedited" shipping options your order will not be shipped any faster but it may arrive quicker if the USPS doesn't lose or delay it. In other words, we will make sure you get your order but you may need to be patient with the USPS.
Returns will be accepted so long as the circumstances are reasonable. We reserve the right to determine what is reasonable. To request a return use the email address on the CONTACT page. The buyer pays return shipping and the original shipping cost will be deducted from your refund. Items must be returned in the same condition they were received or additional deductions may be withheld.
By federal law (posted below) no state or local government can prohibit the sale of airguns but other restrictions can be imposed. It's YOUR responsibility to abide by the laws in your area. If you buy a gun or the parts to build one and then find it's restricted or unlawful that's YOUR problem. It's legal for us to ship parts to any location in the US, all US territories and most countries but it may not be legal for YOU to posses the gun you modify or build with them. We reserve the right to refuse shipping of some parts and complete airguns to specific locations to avoid potential legal hassles.
The following summary contains sections of federal law that pertain to the sale of airguns. It explains that traditional pellet guns, BB guns and paintball guns are not considered to be replica, imitation or look-alike firearms. They are not required to have markings indicating so. No state or local government can require such marks or prohibit the sale of these guns, though many states restrict their possession and use in other ways. This law starts out by specifying that toy guns, which includes airsoft, are required to have special markings. We left subsections out that were irrelevant to pellet guns and highlighted in blue the ones that specifically pertain to them.
