Re: Building an M-110 type service rifle
Well, I guess they have updated:
From
http://www.nrahq.org/compete/RuleBooks/HPR/hpr-index.pdf <span style="font-style: italic">3.1.6 Service Rifle - U.S. Rifle, Caliber 7.62mm M-110 series as issued by the U.S. Armed Forces, or the
same type and caliber of commercially procured rifle without bipod, having not less than a 4 1/2 pound trigger pull
with standard-type stock, pistol grip, handguard, and leather or web sling. In all courses of fire and in all positions,
the standard 20 round box magazine or a reduced magazine of the same external dimensions will be attached.
The gas system must be fully operational. External alterations to the barrel, upper and lower receivers, stock,
handguard, or pistol grip will not be allowed, except that plastic covers may be used on the mounting rails on the
handguard. The flash suppressor may be removed or the rifle may be manufactured without a flash suppressor.
Barrel length may not exceed 20 inches, as measured to the end of the rifling in the barrel. The front sling swivel
must be attached to the end of the handguard, and must remain in the 6 o’clock position no more than 1/2 inches
from its original location. The sights must be of the standard design found on the M16 series of firearms. Rear
sight windage and elevation adjustments may be modified to allow finer adjustments. No optical sights are
allowed. The removable carry handle and front sight assembly must conform to the dimensions specified. The rear
sight aperture and front sight width may vary in width to suit the shooter. The rear aperture may be hooded.</span>
