POF P308 Edge Rifle .308 Win 16.5″ Piston

Description

Let me paint you a picture. You’re at the range with a buddy who’s running a standard DI AR-10. It’s a fine rifle, but after a few mags, you see him wiping down the bolt, complaining about the gas and carbon. You pick up your POF P308 Edge Rifle 308 Win, 16.5″ Barrel, 5 Pos Piston Gas Block, 14.5″ M-Lok Edge Rail, Black, MagPul 20rd, run another 100 rounds of mixed brass and steel-case ammo through it without a hiccup, and the action is still clean and cool to the touch. That’s the real-world difference a purpose-built piston gun makes.

So, what is it? The POF P308 Edge is a semi-automatic, piston-driven rifle chambered in .308 Winchester/7.62x51mm NATO. It features a 16.5-inch barrel with a 5-position adjustable gas block, a 14.5-inch free-float M-Lok handguard, and comes in a black finish with a Magpul 20-round PMAG. It’s designed for reliability, reduced maintenance, and handling that bridges the gap between a heavy battle rifle and a modern sporting platform. At $2019.11, it sits in a competitive space for a feature-complete, American-made piston AR.

I’ve put several hundred rounds of everything from cheap Tula to match-grade Federal through a P308 Edge, and the operating system is its standout feature. That 5-position adjustable piston block isn’t a gimmick. You can dial it to run suppressed with subsonics, open it up for underpowered steel case, or set it to the lightest setting for minimal recoil impulse with quality brass. It fundamentally changes the cleaning routine and the feel of the shot cycle. The gun runs noticeably cleaner and cooler than any direct-impingement AR-10 I’ve used.

The 14.5-inch Edge rail is another win. It’s slim, lightweight, and offers a full M-Lok attachment system at the 3, 6, and 9 o’clock positions. The fit and finish are excellent, with no sharp edges. It provides a solid, comfortable grip and plenty of real estate for lights, grips, or bipods. The rifle uses a standard AR-10/M110 pattern magazine, so your Magpul PMAGs, Lancer L7AWM mags, and other SR-25 compatible magazines are good to go. This is a huge plus for parts commonality.

Here’s the thing—POF builds these to be drop-in ready. You don’t need to be a gunsmith to get it running. The trigger out of the box is a solid single-stage unit that breaks cleanly, a significant step up from a standard mil-spec offering. The rifle balances well for its class, with the weight centered between your hands. The anodized finish is durable, and all the controls—ambidextrous safety and bolt release—are crisp and positive.

Pros & Cons
The pros are clear: exceptional reliability across ammo types, drastically reduced fouling in the receiver, and an adjustable system that lets you tune for suppressors or light loads. The fit and feature set are top-tier for the price. The cons? Piston guns are inherently a bit heavier up front than their DI cousins. Some purists also note a slightly different recoil impulse—it’s sharp but fast. And while the price is fair for what you get, it’s an investment over an entry-level AR-10.

Who is this rifle for? It’s for the shooter who values dependable function over theoretical weight savings. It’s ideal for hunters who might go multiple seasons between deep cleanings, for tactical competitors who need a gun that runs dirty, or for any Missouri shooter who wants a modern .308 that’s built to work without constant babysitting. If you’re tired of gas-in-the-face and carbon-locked bolts, this platform offers a tangible solution.

Frequently Asked Questions

Q: Is the barrel threaded for a muzzle device?

A: Yes, it comes with a standard 5/8×24 thread pitch, so you can easily attach a muzzle brake, flash hider, or suppressor mount. POF typically includes a effective muzzle brake from the factory.

Q: Can I use my existing AR-10 parts and accessories on this rifle?

A: Mostly, yes. It uses a standard DPMS-pattern upper/lower interface and a common magazine pattern. However, the bolt carrier group and some internal parts are specific to the POF piston system and are not interchangeable with standard DI AR-10 parts.

Q: Is it compatible with optics and other standard accessories?

A: Absolutely. The upper receiver has a full-length Picatinny rail for optics, and the M-Lok handguard accepts all modern M-Lok accessories. The rifle is mil-spec compatible for stocks and pistol grips, so personalization is straightforward.
