Frequently Asked Questions

Why did Colt stop producing the AR-15 for commercial sales in the early 1990s?

Colt ceased commercial AR-15 production around 1990-1991 due to political outcry following shootings and the loss of the M16A2 contract. This led to restrictions on sales, limiting them primarily to law enforcement and military use.

What were the key voluntary modifications made to the Colt Sporter series rifles?

The Colt Sporter series featured voluntary modifications like an automatic sear block to prevent full-auto conversion, larger 170 diameter hammer/trigger pins, fixed stocks, and five-round magazine limiters. These changes were made by Colt at their own discretion.

What is the significance of the automatic sear block in Colt Sporter rifles?

The automatic sear block was a steel insert in the lower receiver designed to prevent the installation of auto sears, lightning links, or fully automatic bolt carriers. Its presence made it impossible to convert the rifle to full-auto capability.

Which Colt Sporter model was the first to feature a flattop upper receiver with a 1913 rail?

The R6700 Colt Sporter Competition H-Bar was the first Colt commercial rifle to incorporate a flattop upper receiver with a Mil-Std 1913 rail. This innovation predated the government's standardization of the 1913 rail.
