'''Check It Products''' ('''CIP''', also styled '''Check-It Products''') is an American [[paintball equipment]] brand based in Southern California. Active since at least the early 1990s, the business developed and marketed pump-action [[paintball marker]]s, barrels, trigger frames and aftermarket components.[1][2]

Its early products included the [[Check It Super Stock|Super Stock]], a limited-production stock-class pump pistol manufactured by [[Tri-J Machine]]. Check It Products subsequently marketed [[Autococker]] components and pump conversion equipment.[3][4]

== History ==

=== Early operations ===

Check It Products was associated with Glen Chon and the Southern California paintball community during the early 1990s.

The business developed equipment for stock-class players, including custom pump-action pistols inspired by earlier designs such as the [[Desert Duck]] and [[Carter Boxgun]].

In historical recollections preserved on [[M. Carter Brown]], tournament player [[Derrick Obatake]] described how Glen Chon became interested in producing a commercially manufactured stock-class pistol.

According to Obatake, Chon used an earlier Boxgun design as the basis for developing his own production marker.[5]

The Boxgun itself had been developed through earlier work involving [[Earon Carter]] and [[Dave Loo]].

These accounts establish a design relationship between the early Southern California stock-class markers but do not establish that Check It Products manufactured the original Carter or Duck Works designs.

=== Super Stock ===

The '''Super Stock''' was one of Check It Products' earliest documented complete paintball markers.

[[VintageRex]] dates the marker to 1993 and identifies Tri-J Machine as its manufacturer.[3]

The Super Stock was a compact, .68-calibre, Nelson-style pump pistol intended for stock-class competition.

An original manufacturer brochure advertised the marker as the '''Super Stocker Pump Pistol''' and listed a selling price of US$345.[6]

The marker was also documented in the December 1995 issue of ''[[Action Pursuit Games]]'', providing contemporary evidence of its availability during the mid-1990s.[7]

VintageRex records a production total of 350 examples, although this figure has not been independently verified.[3]

=== Expansion into aftermarket components ===

Check It Products subsequently expanded its range of paintball equipment.

By the 2000s, the company was known for manufacturing aftermarket barrels, trigger frames and other components for existing paintball markers.

A manufacturer listing maintained by [[WARPIG]], verified on 30 August 2007, identified Check It Products as a manufacturer of paintball barrels and accessories, including trigger frames.[2]

A contemporary industry directory listed the company at 16921 South Western Avenue, Suite 112, Gardena, California.[1]

=== Later pump equipment ===

Check It Products also marketed pump-action equipment based on the [[WGP Sniper]] and Autococker platforms.

Its documented products included the '''V2 Autococker Mini Sniper''', a pump-action marker incorporating Check It's own components.

The V2 featured a stainless-steel valve assembly, adjustable regulator, Delrin pump handle, Autococker-threaded barrel and components intended for low-pressure operation.[8]

Check It also offered complete pump conversion kits for Autococker-compatible markers.

These products represented a continuation of the company's involvement in pump-action paintball beyond its original stock-class pistol designs.[8][9]

== Paintball markers ==

=== Super Stock ===

The '''Check It Super Stock''' was a .68-calibre pump-action paintball pistol designed for stock-class competition.

It used a Nelson-style valve system with a fixed stainless-steel barrel and an integrated CO₂ cartridge changer in the grip.

Unlike conventional pump markers using a separate cylindrical receiver and barrel, the Super Stock featured a compact pistol-style body.

The marker used a sliding trigger arrangement and a spring-assisted pump return system.[3][6]

=== Construction and features ===

The original manufacturer advertisement documented several features of the Super Stock:[6]

* Fixed stainless-steel barrel, approximately 5.5 inches long.
* Precision-machined and honed barrel with a stated bore diameter of .691 inches.
* Polished, velocity-adjustable bolt and hammer.
* Fixed blade sights.
* Uncle Mike's rubber grips.
* Posi-Drop stock-class feeding mechanism.
* Pump return spring.
* Sliding-action trigger.
* Integrated 12-gram CO₂ cartridge changer.

The advertisement stated that the marker complied with the guidelines of the Stock Gun Players Association.

It was supplied with a breakdown tool, velocity-adjustment rod, instructions and a 90-day manufacturer's warranty.[6]

An additional instruction sheet described a stainless-steel body, adjustable bolt and hammer, and a quick-twist CO₂ changer.[10]

The Super Stock was offered with fixed blade sights, while VintageRex also records optional Millet adjustable or Bomar fixed sights.[3]

=== Other markers ===

Check It Products subsequently marketed pump-action markers and configurations based on the Autococker platform.

The '''V2 Autococker Mini Sniper''' was a later commercial product using a conventional closed-bolt pump mechanism rather than the compact stock-class configuration of the original Super Stock.[8]

Historical Autococker catalogues also identify Check It Products with Dragon and Pro Series customised Autocockers.[11]

The production dates and full specifications of these additional configurations require further documentation.

== Other equipment ==

=== Barrels ===

Check It Products manufactured aftermarket paintball barrels for a range of markers.

The company was identified as a barrel manufacturer in WARPIG's industry directory in 2007.[2]

Its historical products included specialised barrel designs and equipment intended for Autococker-compatible markers.

=== Pump conversion kits ===

Check It Products produced pump conversion kits for existing mechanical semi-automatic markers.

These kits allowed compatible Autococker markers to be converted to manual pump operation by replacing the pneumatic recocking components with a mechanical pump assembly.

The Check It Mini Cocker Deluxe Pump Kit incorporated stainless-steel guide rods, an aluminium adaptor, Delrin pump handle and internal pump return spring.[9]

=== Autococker components ===

Check It Products manufactured and marketed replacement components for the Autococker platform.

Documented products included:

* Pump conversion assemblies.
* Trigger frames.
* Replacement bolts.
* Stainless-steel valve assemblies.
* Adjustable regulators.
* Rebuildable ball detents.
* Valve installation and removal tools.
* Replacement internal components.

The company's rebuildable ball detent incorporated interchangeable Delrin and stainless-steel balls and a removable assembly intended to simplify cleaning.[12]

These products were marketed for use with compatible Autococker and Sniper markers.

== Relationship with other manufacturers ==

Check It Products was part of the specialist aftermarket paintball equipment industry that developed around the popularity of mechanical pump and semi-automatic markers.

Its early Super Stock was manufactured by Tri-J Machine and drew on the Southern California tradition of custom stock-class pistol design.

The company's later products included components compatible with the Autococker platform manufactured by [[Worr Game Products]].

Although Check It's historical equipment was associated with other manufacturers' designs, these relationships should not be interpreted as evidence of common corporate ownership.
