Surprise! It does not stand for Assault Rifle. The AR in AR-15 stands for Armalite, who is the original designer and manufacturer of the AR-15.

Luckily you can purchase right here on the website. Of course full firearms and lower receivers are considered to be restricted items and must be shipped to an FFL.

So add your configured SIONICS firearm or lower receiver to the cart and in the additional notes add the information for your FFL. We will reach out to them and get a copy of their license and then let them know when its on its way to them!

All SIONICS firearms and products must be paid for in full at the time of order to ensure there aren’t complications when it comes time to shipping.

Here at SIONICS, we test fire EVERY BCG, upper receiver group, and firearm.

Our test firing process is simple:

• BCGs get 5 rounds of M193 and another single round in a separate magazine to ensure function, ejection pattern, and lock-back.
• All upper receiver groups and firearms get 7 rounds of M193 and another single round in a separate magazine to ensure function, ejection pattern, and lock-back.

SIONICS handguards are incredibly rigid and the inherent design features ensure anti-rotation. Through rigorous testing both by SIONICS and the many LE agencies using SIONICS rifles we can ensure zero retention when using IR/VIS aiming devices.

SIONICS handguards feature QD attachment points at the forward and rear 3 and 9 o’clock positions. SIONICS QD receiver sockets are anti-rotational.

SIONICS triggers have an extremely clean break due to the NiB plating and our stringent machining and QC processes. SIONICS triggers also have an incredibly tactile reset allowing for quick and easy follow up shots or high round count strings of fire.

By sending all of our barrels to Radiograph, or X-Ray testing we are able to identify possible structural defects within the barrel.

This is an example of a barrel defect that would not be detected to the naked eye.
