Once again.

Dwarf versus the only citation.

Dwarf v. Dwarf.

Stand back.

I have already posted multiple citations saying the Sporter was designed for Civilians.

You have posted none that says it was designed for the battlefield.

You have posted nothing of what you claimed was modified.

The M16 fired a 5.56.  The Sporter fired a .223.  

The barrel twist was different.

Comparison to military versions

The primary distinction between civilian semi-automatic rifles (no longer manufactured by Colt for civilian use) and military models is select fire. Military rifles were produced with firing modes, semi-automatic fire and either fully automatic fire mode or burst fire mode, in which the rifle fires three rounds in succession when the trigger is depressed. Most components are interchangeable between semi-auto and select fire rifles including magazines, sights, upper receiver, barrels and accessories.[19][20] The military M4 carbine typically uses a 14.5-inch (370 mm) barrel. Civilian rifles commonly have 16-inch or longer barrels to comply with the National Firearms Act.[21]In order to prevent a civilian semi-automatic AR-15 from being readily converted for use with the select fire components, Colt changed a number of features. Parts changed include the lower receiver, bolt carrier, hammer, trigger, disconnector, and safety/mode selector. The semi-automatic bolt carrier has a longer lightening slot to prevent the bolt's engagement with an automatic sear. Due to a decrease in mass the buffer spring is heavier. On the select fire version, the hammer has an extra spur which interacts with the additional auto-sear that holds it back until the bolt carrier group is fully in battery, when automatic fire is selected.[22] Using a portion of the select fire parts in a semi-automatic rifle will not enable a select fire option.[23] As designed by Colt the pins supporting the semi-auto trigger and hammer in the lower receiver are larger than those used in the military rifle to prevent interchangeability between semi-automatic and select fire components.[24]
