2. What is the difference between the "M" and "C" Carriers?
The difference is in the venting of the carriers. The "M" has more venting and will run slower than the "C" if used in the same firearm with the same ammo. All other parts of the ARIC are identical.

3. Which ARIC should be used with an Adjustable Gas Block?
ARIC selection is based on standard gas ports. It may be possible for adjustable gas blocks with multiple settings to run the "C" Carrier suppressed and or unsurpassed by adjusting the setting. Due to the variety of adjustable gas blocks on the market, Law Tactical cannot provide specific recommendations.

4. Can I use a Picatinny Adapter or other parts to eliminate the need for a buffer tube?
Law Tactical has developed Picatinny and other adapters for future release. ARIC was developed as a drop in component for Law Tactical AR Folding Stock Adapters to maintain full backwards compatibility with standard bolt carrier groups and recoil systems. Removal of the buffer tube removes backwards compatibility. Potential changes to AR pistol rules may make it advantageous to maintain backwards compatibility, as it provides a functional reason for a buffer tube and other accessories to be attached to an AR pistol.
5. How is the ARIC backward compatible?
Firearms with the Law Tactical Folding Stock Adapter and the ARIC, can be swapped between the ARIC and standard bolt carrier groups, and recoils system with out the use of tool.

6. Is ARIC compatible with .300 BlackOut?
Many 300 Blackout firearms will function properly with both “M” or “C” Carriers. However, due to lack of standardization, the "M" Carrier may not reliably function with some subsonic ammunition in certain configurations of barrels, gas ports, and suppressors.

Is ARIC compatible with Alternate Bolts/Calibers?
The use of alternate bolts/calibers is not recommended and would still require use of the LT Cam Pin, One Piece Gas Ring and LT Firing Pin Retaining Pin for operation.

Colt “cut/notched” semiautomatic hammers due to known function issues with standard BCGs, Binary/Forced-reset or other similar style triggers.

10. Can I use ARIC in a Piston Gun (OP-Rod Gas Piton Operated Firearms)?
Law Tactical has developed Gas Piston compatible ARICs, however, each Piston Manufacturer uses a proprietary design. As such each Piston Firearm Requirers its own modifications. ARIC is currently for Direct Impingement gas systems only.

11. Can I use ARIC in a 9mm Blowback System?
ARIC is not compatible with 9mm or other Blowback systems.
