Weighing in at roughly 7.5 pounds unloaded, this POF Gen 4 manages to keep the heft down for a .308 rifle. That’s a practical tradeoff for all-day carry, though remember you’re still hauling .308 ammo. The pinned 14.5-inch barrel is a clever move—you get the ballistic and handling benefits of a shorter barrel without the NFA paperwork, a real value-focused solution. At $2295.28, it sits in a competitive spot. You’re paying for the piston system and POF’s fit and finish, but is it worth it over a well-built DI gun? For many, the cleaner running and cooler operation justify the cost, especially in a compact package.
Who This Rifle Is For
This rifle is built for the practical shooter who needs a dependable, hard-use .308 but doesn’t have a custom shop budget. Think of the hunter in dense Missouri timber who wants a maneuverable rifle, the tactical competitor looking for a soft-shooting edge, or the prepared citizen who values a compact, powerful defensive tool. It’s for someone who understands that a piston gun’s upfront cost can mean less maintenance and more reliability down the line. It’s also compatible with a wide range of SR-25 pattern parts and accessories, so customization is straightforward.
Pros & Cons
Pros: Piston reliability and cleaner operation. Lightweight for a .308 platform. The fluted barrel is both functional and looks sharp. The adjustable gas system lets you tune for suppressors or different ammo. High-quality out-of-the-box trigger. Fits out of the box with no gunsmithing required for most standard accessories.
Cons: Higher price point than entry-level AR-10s. Piston systems can be slightly heavier up front than DI. Proprietary bolt carrier group design means standard AR-10 parts won’t always interchange. Magazine cost is higher than standard AR-15 mags.
Frequently Asked Questions
Q: Is the muzzle device permanently attached?
A: Yes. The 14.5-inch barrel has a muzzle device pinned and welded to achieve a legal 16-inch overall barrel length, so no NFA tax stamp is required. This is a common and compliant practice for factory rifles.
Q: What magazines does it use?
A: It uses the common SR-25 / DPMS pattern .308 magazines. Reliable brands like Magpul PMAG 25 LR/SR Gen M3 are a great, cost-effective choice and are widely available.
Q: Can I use a standard AR-15 buffer tube and stock?
A: No. The .308/AR-10 platform uses a larger receiver extension (buffer tube) than an AR-15. You’ll need a stock and buffer system designed for an AR-10/SR-25 pattern rifle.
Look, if you’re after the bang-for-your-buck in the premium factory rifle segment, this POF Gen 4 makes a strong case.
