Battle Arms Workhorse 223 Wylde 16″ Fixed Magazine — Superb Compliant AR

Description

The Battle Arms Workhorse is a properly built AR-15 rather than a parts-bin one, and this particular configuration carries a feature that needs stating up front: it is fitted with the BAD-MRB conversion, which prevents the magazine release from functioning while the upper receiver is attached. That is a compliance feature, and whether it is an advantage or an obstacle depends entirely on where you live.

The Magazine Lock, Explained Plainly

The BAD-MRB conversion means the magazine cannot be released with the rifle assembled. To change magazines you separate the upper from the lower at the takedown pin, which allows the release to function. This is how a rifle is made to comply with fixed-magazine requirements in states that restrict detachable-magazine semi-automatics, and it ships with a 10-round magazine to match.

For a buyer in a restricted state, that is precisely what makes this rifle available to them at all. For a buyer in Pennsylvania or anywhere else without those restrictions, it is a limitation with no corresponding benefit, and the standard Battle Arms Workhorse without the conversion is the better purchase. We would rather you knew that before ordering than after.

On the 223 Wylde chamber specifically: it is cut with the leade of a 5.56 NATO chamber but the tighter dimensions of a .223 match chamber, which means it handles 5.56 pressures safely while shooting .223 more accurately than a standard 5.56 chamber would. It is the sensible chambering for a rifle that might see either, and it costs nothing extra to have.

Why it is worth considering

• Forged 7075-T6 BAD-15 receiver, not cast
• 4150 chrome-moly nitride barrel in 223 Wylde
• Mid-length gas system, softer impulse than carbine length
• 15 inch M-LOK free float rail with full-length top Picatinny
• B5 Bravo stock rather than a generic mil-spec one
• BAD-MRB conversion for fixed-magazine compliance where required

Who it suits

The Battle Arms Workhorse in this configuration is for a buyer in a state that requires a fixed magazine. If that is you, this is a considerably better rifle than most of what is available to you, and the compliance hardware is the reason you can have it. If you are not in such a state, buy the standard Workhorse instead — the same rifle without the magazine lock, and no reason to accept the limitation.

Ammunition, Magazines and Transfer

The Battle Arms Workhorse runs both 5.56 NATO and .223 Remington thanks to the Wylde chamber. For practice, 55 grain ball is the cheapest option; for anything requiring precision, 69 to 77 grain match bullets are where the chamber earns its keep. Magazines are standard AR-15 pattern, but remember that with the MRB conversion fitted you will be separating the upper and lower to change them, which makes range sessions with several magazines slower than usual.
