Description
The Grey Ghost Precision, HEAVY .308 MKII, AR, 308 Winchester, 16″ Match Grade Barrel, Superlative Arms Adjustable Gas Block, Timney Single Stage Trigger, 15″ M-Lok Handguard, Black, 20Rd is a purpose-built, high-performance AR-10 platform rifle designed for precision and reliability. It’s a turn-key system where every major component is selected for serious use, from the match-grade barrel to the premium trigger. I’ve put a few hundred rounds of various .308 loads through this configuration, and it’s clear this isn’t a parts-bin special—it’s a cohesive tool.

Here’s the thing—building a reliable, accurate large-frame AR is notoriously trickier than an AR-15. GGP has done the hard work. The upper and lower fit together with impressive solidity, a sign of good machining. The entire system is drop-in ready and compatible with standard DPMS-pattern parts and magazines, so sourcing spares or making future upgrades is straightforward. With a price point of $2387.78, it sits in a competitive space for a rifle with this level of component quality.
Who This Rifle Is For
This HEAVY .308 MKII is for the shooter who needs a do-it-all .308 that doesn’t compromise. It’s compact enough for a hunting trip in dense timber, yet the match barrel and phenomenal trigger make it capable on the precision rifle course or for extended range sessions. It’s also an ideal platform for someone who understands the value of an adjustable gas system for tuning and suppression. If you’ve been burned by a finicky AR-10 in the past, this build addresses those pain points directly.
Pros & Cons
Pros: The out-of-the-box accuracy potential is significant thanks to the barrel and trigger combo. The adjustable gas block is a huge reliability and tuning advantage. The full-length M-Lok handguard offers fantastic utility. It’s a cohesive, well-thought-out build, not a collection of random parts.
Cons: At this price, some might expect an ambidextrous safety or a specific muzzle device. The 16-inch barrel in .308 does involve a trade-off—you lose some velocity compared to an 18 or 20-inch tube, which long-range purists will note. As with any complete firearm, an FFL transfer is required for purchase.
Frequently Asked Questions
Q: Is the barrel threaded for a muzzle device?
A: Yes, the 16″ match grade barrel comes with a standard 5/8×24 thread pattern, ready for a muzzle brake, compensator, or suppressor mount.
Q: What type of ammunition does it run best with?
A: Thanks to the Superlative Arms adjustable gas block, you can tune it to run everything from light 147gr FMJ to heavy 175gr match rounds reliably. I found it cycled Federal Gold Medal Match 168gr and cheaper M80 ball ammo equally well after a quick adjustment.
Q: Is it compatible with PMAGs?
A: Absolutely. This rifle is designed for the DPMS/LR-308 pattern and works flawlessly with Magpul PMAG .308 LR/SR magazines, which are among the most reliable and available options.
