Can I Build an AR-15 in Connecticut?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
You can build an AR-15 in Connecticut, but it must comply with the state's assault weapon ban. This means no flash hiders, bayonet lugs, collapsible stocks, or pistol grips that protrude below the action.
What This Means for You
Connecticut's assault weapon laws don't ban AR-15s outright, but they severely restrict the features you can include. The state uses a feature-based definition that prohibits specific combinations of accessories and design elements. Most builders focus on creating compliant configurations rather than attempting to work around the restrictions.
The Detail
Connecticut defines assault weapons by their features rather than banning specific models. For rifles, you cannot have a detachable magazine combined with any prohibited features like flash suppressors, bayonet mounts, folding or telescoping stocks, or pistol grips that protrude conspicuously below the action of the weapon.
The pistol grip restriction is particularly challenging for AR builders since the standard AR grip design clearly protrudes below the receiver. Connecticut-compliant builds typically use specially designed grips that maintain a more traditional rifle stock angle, often called "featureless" grips. These grips eliminate the finger groove and thumb shelf while keeping your trigger hand in a more conventional rifle position.
Stock selection becomes straightforward since you must use a fixed stock design. Standard A1 or A2 fixed stocks work perfectly, as do many commercial fixed rifle stocks. The flash hider restriction means you need either a bare muzzle, a muzzle brake that only redirects gases sideways or backward, or a compensator design that doesn't suppress flash.
Magazine capacity adds another layer of complexity. Connecticut restricts magazines to 10 rounds for rifles, with some exceptions for pre-ban magazines owned before certain dates. You should verify the current magazine restrictions with state resources since these laws have changed multiple times and include various grandfather clauses and ownership requirements.
Build Impact
Your Connecticut AR build will look and function differently from standard configurations, particularly regarding the grip angle and stock type. The compliance requirements significantly limit your component choices but don't prevent you from building a functional rifle.
