This guide details how to build a compact AR-15 rifle, focusing on achieving a shorter overall length without violating NFA regulations. It highlights the use of specific components like the Law Tactical Folding Stock Adapter and ARIC system, which allow the rifle to function with a folded stock. The guide emphasizes barrel length considerations, particularly the 13.9-inch barrel paired with a pinned and welded muzzle device to meet the 16-inch legal minimum for rifles. Expert instruction from Brownells covers component selection and assembly for a lightweight, versatile firearm.

Quick Summary

Build a compact AR-15 rifle that avoids NFA registration by using a 13.9-inch barrel and permanently attaching a muzzle device via 'pin and weld' to meet the 16-inch legal minimum. Components like the Law Tactical Folding Stock Adapter and ARIC BCG allow the rifle to function with a folded stock, maximizing compactness for storage and transport.

Frequently Asked Questions

How can I build a compact AR-15 rifle without registering it as an SBR?

To build a compact AR-15 that is not an SBR, use a barrel at least 16 inches long. A common method is to use a 13.9-inch barrel and permanently attach a muzzle device via a 'pin and weld' process to reach the legal 16-inch minimum. Components like the Law Tactical Folding Stock Adapter and ARIC BCG further enhance compactness.

What is the purpose of the Law Tactical ARIC?

The Law Tactical ARIC (AR Internal Carrier) is a specialized bolt carrier group that integrates the buffer and recoil spring directly into the BCG. This design allows an AR-15 to function reliably even when the stock is folded, which is crucial for compact builds utilizing folding stock adapters.

What barrel length is recommended for a compact AR-15 build to avoid NFA issues?

For a compact AR-15 build intended to avoid NFA registration as a Short-Barreled Rifle (SBR), a barrel length of 13.9 inches is often chosen. This length, when combined with a pinned and welded muzzle device, allows the overall legal barrel length to reach the minimum requirement of 16 inches.

Can an AR-15 be fired with the stock folded?

Yes, an AR-15 can be fired with the stock folded if it is equipped with specific components like the Law Tactical Folding Stock Adapter and the Law Tactical ARIC bolt carrier group. The ARIC integrates the buffer system, enabling operation in the folded configuration.
