 I get constant questions about "ping" and "de-pingers" from customers. Many falsely believe ping is caused by air flowing through the valve when the gun is fired. This is not even partially correct. If you don't want to take my word for it there's a simple test you can do. Place a soft-wood dowel against the valve stem and tap it with a hammer to open the valve. There's absolutely no ping when you fire an airgun this way. Ping is caused by the striker hitting the valve stem. The tube resonates like a bell to amplify ping. The depingers most sell reduce resonance in the tube but do not eliminate ping. They have a small hole to allow air flow to the valve. The smaller the hole the more resonance it defeats. The problem is, this works better when the depinger is close to the valve. This cuts air flow to the valve which reduces power. A better way to reduce ping is to use a striker with a vibration dampener. If designed correctly this can nearly eliminate ping without affecting power as much. I have a striker design in the works, I will try to make these available soon.

 This will be a busy year for new parts. There's too many to list them all here but I will update this post as new parts arrive and others begin production. Scheduled to be available within the next month or two are the following :

1) Custom fill heads that fit all 22XX and PCP models with 7/8" OD tubes. They have a knurled thread-on cap and one version has a burst disk and pressure gauge.

2) Shortened Discovery & Maximus tubes. These will be available in a couple sizes and versions.

3) Magnum Adjusters for Marauder Pistol, 1701P, 1720T and 13XX. These new versions are compatible with the same degassing tool used for Discovery, Maximus and Challenger. New adjusters for 22XX, Discovery and Maximus will be available that fit the degassing tool.

4) Custom valves for Discovery and 22XX. This includes a balanced valve that produces more power with less striker spring force required. This will be a true balanced valve with a completely new design. 

5) Aliminum trigger frame and cover for Discovery, Maximus & 2260. This will fit the custom sear I have listed which doesn't fit the plastic frame.  

6) .357 Conversion kit for Discovery and 22XX. This is scheduled to be available around mid to late summer if all goes as planned.

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 special markings indicating so and no state or local government can pass a law or ordinance prohibiting the sale of these guns. This law starts out by specifying that toy guns, which includes airsoft guns, are required to have special markings. We left those sections out because we don't sell toy guns.

15 U.S.C. 
United States Code,  2010 Edition
Sec. 5001 - Penalties for entering into commerce of imitation firearms

(a) Acts prohibited

It shall be unlawful for any person to manufacture, enter into commerce, ship, transport, or receive any toy, look-alike, or imitation firearm unless such firearm contains, or has affixed to it, a marking approved by the Secretary of Commerce, as provided in subsection (b) of this section.

​(c) “Look-alike firearm” defined

For purposes of this section, the term “look-alike firearm” means any imitation of any original firearm which was manufactured, designed, and produced since 1898, including and limited to toy guns, water guns, replica nonguns, and air-soft guns firing nonmetallic projectiles. Such term does not include any look-alike, nonfiring, collector replica of an antique firearm developed prior to 1898, or traditional B–B, paint-ball, or pellet-firing air guns that expel a projectile through the force of air pressure.

​(g) Preemption of State or local laws or ordinances; exceptions

The provisions of this section shall supersede any provision of State or local laws or ordinances which provide for markings or identification inconsistent with provisions of this section provided that no State shall—

(ii) prohibit the sale (other than prohibiting the sale to minors) of traditional B–B, paint ball, or pellet-firing air guns that expel a projectile through the force of air pressure.
