C1-Buttstock

The C1 is an A1 length (5/8" shorter than an A2 stock) and shape fixed buttstock. The shorter length of pull makes it well suited for use with heavy clothing, body armor, and by shooters of smaller stature. Many also prefer it because it allows the shooter to more easily assume a "nose to the charging handle" cheek weld" The C1 has a larger trap door compartment than that of other AR15 buttstocks, because the buffer tube channel and trap door compartment are formed in the mold. The sling swivel can be offset to either left or right in addition to straight down. The C1 is injection molded from glass filled nylon 6, and comes with our injection molded buttplate/ trap door, sling swivel, and shorter screw. (Most manufacturer's A1/A2 buttplate assemblies will work with the C1.)

This buttstock meets the requirements for CMP Service Rifle competition.  In rule 6.2.3 "U.S. Rifle, Caliber 5.56 mm, M16" starting on page 29 of the 2014-2015 Competition Rulebook, it describes the rules for M16/AR15-style service rifle buttstocks:

An M16A1 rifle (short) butt stock or pistol grip or its commercial equivalents may be installed in lieu of the M16A2 or M16A4 butt stock or pistol grip. A fixed-length aftermarket stock that reduces the length of pull to no less than 10 inches may also be installed on an M16A2 or M16A4 rifle or a commercial equivalent rifle. Any aftermarket stock must have the same external characteristics as the A2 or A1 stocks except for the shorter length. Collapsible stocks of the type used on M16 M4/M4A1 Carbines are not permitted. The same butt-stock must be used for all stages of a competition.  (emphasis added)
