6.0 Firearms, Ammunition and Equipment

6.1 CMP Highpower Rifle Rules

Rifles that comply with this rule may be used in CMP-sanctioned matches in accordance with these rules and/or the match program. A CMP Service Rifle is defined as any rifle that complies with Rules 6.1.1, 6.1.3 or 6.1.4. A CMP Alternative Rifle is any rifle that complies with Rule 6.1.2. A Match Rifle is any rifle that complies with Rule 6.1.5.

6.1.1 M16/AR15-Type Service Rifle. 

The rifle must be an M16 U. S. Service Rifle or a similar AR15-type commercial rifle that is derived from the M16 service rifle design. Rifles must exhibit the general overall external

appearance of the M-16 rifle or carbine. Visible barrel profiles, handguards or quad rails, receivers, pistol grips, carry handles or rails and fixed or collapsible stocks must appear essentially the same as the M16 service rifle and must incorporate the following features; functional forward assist, integral case deflector, functional ejection port cover, MIL-SPEC standard charging handle, and a Picatinny rail located at standard MIL-SPEC height. The following specific rules apply to this rifle:

a) Cartridge. Must be chambered for the 5.56 x 45 mm NATO (.223) cartridge.

b) Action. Must be designed or modified so that only semi-automatic fire is possible. The gas operating system must be fully operable and adhere to the original M16 rifle design (i. e. Stoner design, gas impingement system) or have a piston-operated gas system. Adjustable gas blocks are not permitted. A gas block without a front sight is permitted. Left-handed receivers that reverse the operational design features of M16/AR-type rifles are permitted. An extended bolt release is permitted on both right and left-handed receivers, provided there are no permanent alterations to upper or lower receivers.

c) Barrel. Barrel length may not exceed the standard A2 barrel length of 20 inches, as measured from the bolt face to the end of the barrel. Flash suppressors are not required, but if the barrel has a flash suppressor the length of the barrel measured from the bolt face to the end of the flash suppressor shall not exceed 21 ¼ inches. No full-length heavy barrels are permitted. No portion of the barrel forward of the rearward location of the gas block or front sight tenon shall have a diameter exceeding .750". Upper receivers and/or barrels may not be changed during the firing of any event. Standard rifle length gas systems must be used for 20 inch barrels; carbine length gas systems may be used for barrels less than 20 inches.

d) Trigger. Triggers may be either two-stage or single-stage. Triggers may be adjustable, provided all adjustments are internal. Triggers must be of standard curved design; trigger shoes are not permitted. The trigger pull must be at least 4.5 pounds.

e) Handguard. The receiver and handguard must be machined as separate parts. Standard M16-type service handguards (which may conceal a float tube) may be used or military design or aftermarket free floating rail systems may be used, provided they meet the following criteria. The rail may be of one or multiple piece design and be attached to the receiver by means of the rail itself or with a standard or special barrel nut. The rail must have a continuous Picatinny rail section on the 12 o’clock position that does not exceed the height of the receiver. The rail must have Picatinny rail sections at the 3, 6 and 9 o’clock positions for a minimum of half the length of the handguard. Key-Mod, M-Lok or similar mounting systems are permitted. Handguards may be of any length and the front sling swivel may be attached to the hand guard, but any front sling swivel location must be fixed 13 in. (+/- 0.5 in.) from the forward edge of the magazine well on M16 configured rifles or 8.0 in. (+/- 0.5 in.) on M4 configured rifles.

f) Butt-Stocks. Butt-stocks may vary in length and be either fixed or adjustable. Adjustable length butt-stocks may be changed during an event, but butt-stocks that allow other adjustments such as the cheek-piece height or butt-plate location are not permitted. Only standard A1 or A2 type pistol grips are permitted.

g) Magazines. Metal or synthetic (polymer) magazines, standard issue or commercial equivalent, straight or curved, with standard service 20 or 30-round box magazine dimensions must be attached during the firing of all courses and in all positions. A 10-round magazine with the same external dimensions as a standard service 20-round box magazine may be used. A dummy magazine with a ramp for single shot loading may be used if this magazine has the same external dimensions as the standard service 20-round box magazine.

h) Optical Sights. The rifle may have an optical sight (reflective sights are considered optical sights) with a maximum power of 4.5X installed on the receiver. Variable scopes with a maximum of 4.5X are permitted. Only commercially manufactured scopes that were produced with a maximum magnification of 4.5X and have a maximum objective lens diameter of 34 mm may be used. If an optical sight is used, the same optical sight configuration must be used in all stages of a course of fire (changing sights or sight mount configurations is not permitted). The centerline of an optical sight shall be no higher than 3.5 inches above the centerline of the bore.

i) Metallic Sights. Alternatively, the rifle may be equipped with an issue style fixed front sight assembly, removable front sight, or a collapsible front sight. All types must utilize a sight post and have a maximum sight radius of 20.5 inches. Metallic rear sights, if used, must have an M16 type sight design with the rear sight in the carry handle.
