Frequently Asked Questions

What is the Law Tactical ARIC and RAP system?

The Law Tactical ARIC (AR Internal Carrier) is a self-contained bolt carrier and buffer system. It's paired with the RAP (Rail Adapter Plate), which adds a 1913 rail to the receiver's rear, allowing for folding stocks without a traditional buffer tube, ideal for compact builds.

What barrel length and caliber are recommended for a backpack AR-15?

For a compact backpack AR-15, a 12.5-inch barrel chambered in .223 Wylde is recommended. This length offers a good balance of portability and ballistic performance, while .223 Wylde ensures compatibility with both .223 Remington and 5.56 NATO ammunition.

How can an AR-15 be made more compact for discreet carry?

To make an AR-15 more compact for discreet carry, use folding stock mechanisms like the Law Tactical ARIC/RAP system. Choosing a shorter barrel (e.g., 12.5 inches) and a low-profile optic, along with a shorter stock, further reduces the overall size for easier transport in a backpack.

What are key considerations when installing the Law Tactical RAP?

When installing the Law Tactical RAP, it's crucial not to over-tighten the set screw. This ensures the ARIC carrier can move freely within the receiver, which is essential for the firearm's proper function and reliability.
