2A Armament Balios Lite Billet Receiver Set Review Comments Off on 2A Armament Balios Lite Billet Receiver Set Review

2A Armament Balios Lite

2A Armament makes a wide range of high quality AR-15 products, from lightweight adjustable bolt carrier groups, to gas blocks, handguards and complete rifles and AR pistols. However, their lightweight, Balios Lite billet receiver set, is perhaps one of their best known products.

As of early 2022, the Balios Lite receiver sets are still out of stock from just about every online retailer that I checked. You can always sign up for the “Email me when Back-In-Stock” notifications.

In this article, we showcase a lightweight AR pistol build using the 2A Armament Balios Lite, Gen 2, billet receiver set.

2A Armament Balios Lite Billet Receiver Set Fit and Finish

The upper and lower receiver fit was so incredibly tight that it was difficult to line them up enough to be able to push through the takedown pins. The machining is excellent and the anodized finish is smooth.

It was also obvious how 2A Armament went about reducing the weight of its Balios Lite receivers. This can be seen particularly from the receiver walls, which are noticeably thinner than on most receivers. Due to the thinner receiver walls, it is recommended that you use 2A Armament’s takedown pins (steel or titanium) because many other brands of takedown pins have a beveled edge at the ends of the pins which can protrude ever so slightly, preventing the upper receiver from sliding into the lower receiver. For instance, I can tell you that the Lantac titanium takedown pins won’t work because they prevent the upper and lower from fitting together. 2A Armament should mention this on their website.

What I Don’t Like about the 2A Armament Balios Lite Billet Receiver Set

While the integrated trigger guard on the Balios Lite is much narrower than I prefer, I particularly do not like how the outer edges are so minimally rounded off that they feel sharp against the finger.

Total Weight of the this 2A Armament Balios Lite Pistol Build

I believe the Balios Lite is currently the lightest (12.3 oz) stripped billet receiver set on the market (V Seven’s LR-Enlightened Receiver Set is a close second at 12.8 oz).

That said, the goal was to build a relatively lightweight, but not necessarily the lightest AR pistol possible, without the use of carbon fiber, preferring metal parts instead.

At 4.5 lbs (without optics), this Balios Lite build is still pretty lightweight. Keep in mind that the YHM mini muzzle brake alone weighs 3.2 oz. Thus, if a suppressor was not being used, a titanium flash hider could be substituted, which would reduce total weight of this build by about 2 oz. Additionally, if a 2A Armament Titanium Regulated bolt carrier group (5.95 oz) was used, along with a carbon fiber buffer tube and carbon fiber handguard, the total weight of this build could be brought down to about 3.9 lbs.

At the Range

After shooting about 160 rounds of 5.56 NATO 55 gr FMJ (M193), suppressed with a YHM Turbo T2 and an Aero Precision adjustable gas block dialed in, this Balios Lite pistol build ran perfectly. As expected, the pencil barrel heated up the handguard pretty quickly compared to a heavier profile barrel.
