Please read carefully, as there are event rules listed that may not be found in the CMP rules.
9.1.1 Intent and Spirit - The intent and spirit of CMP Rimfire Sporter rules is to provide smallbore rifle target competitions where competitors use low-cost, readily available sporter type, .22 caliber rimfire rifles. Any rifle configuration or item of equipment that is not mentioned in these rules or that is contrary to the intent and spirit of these rules is prohibited. The rifles and equipment permitted in Rimfire Sporter are strictly limited to prevent an “equipment race” from occurring in the Rimfire Sporter discipline.
Note: In Timed Fire and Rapid-Fire stages: after the “Load” command, all actions must be locked open or CLOSED on an empty chamber prior to the “Start” command. Manually holding the action open with the magazine inserted is not permitted. Actions may not be cycled or closed until the competitor is in the firing position with firearm safely pointed down range.

Equipment: Current CMP rules allow for 3 different classes. Any rifle that meets any of the CMP classes for use will be allowed, with the exception that any rifles in the configuration of a modern military style rifle will not be permitted. All rifles still must meet the weight, trigger pull and optic limit requirements. There are NO exceptions to these limits. All classes will be scored together as one.
- Rifle: Overall weight of the rifle may not exceed 7.5 lbs., with sights and magazine. If sling is used, it may be removed when rifle is weighed. Any type of action, semi-automatic or manually operated with a trigger pull of at least 3.0 lbs.
- Stock: Rifles may be configured with non-standard stocks, barrels or configurations. Rifles with thumbhole stocks, adjustable stocks, adjustable cheek-pieces, orthopedically shaped cheek-pieces, or a pistol grip, may be used, provided they comply with weight and trigger pull limitations. The stock may have a sling swivel in a FIXED (non-adjustable) location on the fore end. If the buttstock length of pull or the cheek-piece is adjustable, buttstock length and cheek piece adjustments must remain the same for all three positions. These adjustments should be taped or fixed in a single position. Any magazine extending below the stock may not be used as a palm rest or used for support on the forearm. Barrels may be fluted or have non-standard contours.
- Sling: Standard leather or web sling no wider than 1 1/4 inches may be used in the prone, sitting, or kneeling positions. Must be fixed in at least one position. (Rails with adjustable sling swivels are not permitted).
- Sights: Open sights may be used; receiver sights or a scope not exceeding 6x magnification is permitted. If a variable power scope is capable of greater than 6x, the adjustment device on variable telescopes must be secured with tape or other similar means so that it cannot be changed during match. Check-in seal must remain intact. The magnification must remain at the sealed power during the entire match.
- Barrel: Factory fluted, regular standard and sleeved carbon graphite or aluminum barrels will be allowed.
- Shooting stands are permitted in this event.
- Magazines may only have 5 rounds loaded in them for both practice and competition.
Clothing: A competitor is permitted to wear a maximum of two sweatshirts. Shooting jackets, leather shooting vests, shooting boots, etc. are not allowed. Competitors may wear a standard leather, cloth, or synthetic work glove provided that it is not padded. Ordinary low-cut shoes, work boots, or hunting-style boots may be worn.
