Description

Swampfox Kingslayer red dot, Olight Baldr S light/laser and Strike Industries folding brace included with purchase — added by us here at CSS, not part of the factory package.

This is the MasterPiece Arms Defender in 5.7×28, and it is about as loaded as one of these gets. Strike Industries Dual Folding Adapter with the stabilizer end fitted, a Swampfox Kingslayer up top, an Olight Baldr S (800 lumens plus a green laser) underneath, and the factory threaded barrel wearing its muzzle brake. It ships in the factory hard case with the original 20-round magazine plus two spare 30-round ProMags — 80 rounds of 5.7 ready to go on day one.

Here is the part worth knowing: MasterPiece Arms currently shows this model out of stock, and as we write this there is not one single Defender in 5.7×28 listed on GunBroker. We could only turn up one that has ever sold there. If you have been hunting for one of these, you are not going to just go order it somewhere else — and this one is already built out the way you would have built it yourself.

The Strike adapter is the smart play for the long game, and this one is not the bare version. It carries both rear pieces — the stabilizer that is fitted now, and a separate stock end in the box — and it has Strike’s five-position adjustable cheek riser fitted to the bar, which is a separate add-on cost most people skip. So if you ever decide you want this as a registered short-barreled rifle, the hardware is already sitting here and all you need is the paperwork. As it sits today it is a pistol and it transfers like any other handgun. Full details on the adapter are at Strike Industries.
