Description
The ProMag PM271 turns a standard Ruger Mini-14 or Mini Thirty into something a lot easier to store, haul, and outfit. It swaps the factory wood or synthetic stock for an injection-molded polymer setup that trims weight and adds a side-folding buttstock, so the whole rifle shrinks down for transport, truck cases, and tight storage. It's made in the USA, and the black finish keeps the look clean and no-nonsense.
What the PM271 Brings to Your Mini-14
The pistol grip is where this stock earns its keep for a lot of folks. It gives you a more upright, controllable hold than the classic Mini stock, and there's an internal storage compartment tucked inside the grip for small items like batteries, a folded bore snake, or spare pins. Up front, the forend carries a Picatinny tri-rail, which opens the door to weapon lights, a laser, a vertical grip, or a bipod without needing extra adapters. The side-folding hinge uses a positive locking mechanism so the stock snaps into place when you swing it back open, and a rubber recoil pad rounds out the shoulder end for a bit more grip against your shoulder.
Installing the ProMag Folding Stock
This is a drop-in style swap that most owners handle at home with basic tools. Folks who have run it report the stock is solid once mounted and the lockup feels stable, with several noting how straightforward the install was. A few older or specific-series Mini-14 rifles have called for minor fitment work to seat the receiver and trigger group just right, which isn't unusual when fitting an aftermarket stock to a platform Ruger has built across many years. Take your time, check the fit before you button everything up, and you'll be set.
For Mini-14 and Mini Thirty owners who want a compact, accessory-ready rifle without spending big, the PM271 is a practical, feature-loaded upgrade.

Frequently Asked Questions
What rifles does the ProMag PM271 stock fit?
The PM271 is designed for the Ruger Mini-14 and Mini Thirty platforms. Because Ruger has produced these rifles across many years and series, some older or specific-series models may need light fitment work to seat the receiver and trigger group perfectly. It's worth test-fitting before final assembly.
Does the PM271 come with installation instructions?
Some buyers have noted the stock ships without printed instructions, so a little tinkering may be needed the first time. The good news is it's a drop-in style swap and most owners get it done at home with basic tools. Following a Mini-14 stock-swap walkthrough online can make the process smoother.
Can I mount a light or bipod on the ProMag folding stock?
Yes. The forend features a Picatinny tri-rail, giving you rail space on multiple sides for weapon lights, lasers, a vertical grip, or a bipod. No extra adapters are required to start adding accessories.
Is the folding mechanism secure when locked open?
The PM271 uses a positive locking side-folding design, so the buttstock snaps into place when swung back open. Owners generally describe the lockup as stable and the stock as solid once installed. As with any polymer folding stock, checking the fold and lock action after installation is a smart habit.
