About This Firearm
The CMMG Resolute Mk47 is an AR-15 lower paired with a proprietary 7.62×39 upper — a platform that lets you run AK-caliber ballistics with AR-style controls and ergonomics. At 112 oz (7 lbs) and 33" overall with the stock collapsed, it's about 1.75 lbs lighter than the Galil ACE Gen II and noticeably more compact than the AK-pattern rifles in this caliber. The 7075 T6 aluminum billet receivers are lighter than any steel receiver option, and the AR-15 lower means standard AR accessories — stocks, pistol grips, trigger groups — all fit without adapters.
The 4.3 lb trigger ships as the CMMG ZEROED drop-in unit, which is better than a standard mil-spec AR pull and well ahead of what most AK-pattern rifles come with. The 16.1" salt bath nitride barrel with a 1:10" twist is set up for standard 123gr 7.62×39. There are no iron sights included — the rifle ships optics-ready with an M-LOK handguard and Picatinny top rail, so a red dot or scope is a day-one purchase. The ambidextrous 60/90-degree safety selector works at both AR-standard 90-degree and the shorter 60-degree throw preferred by many competition shooters.
The Mk47 makes the most sense for shooters who already run AR-pattern rifles and want to add 7.62×39 capability with minimal retraining. Unlike most AR-based 7.62×39 platforms, the Mk47 accepts standard AK-pattern magazines — it ships with a Magpul AK PMAG and works with steel, polymer, and drum AK mags. That keeps you in the cheap, plentiful AK magazine ecosystem rather than a proprietary mag situation. A practical first step after purchase is to verify the gas system is tuned for your chosen ammunition, as some owners report needing to confirm function with heavier or surplus loads.

Strengths & Limitations
- The 4.3 lb drop-in trigger ships as a genuine improvement over standard mil-spec AR triggers and well ahead of typical AK triggers (commonly 6-10 lbs stock). Owners report it's usable as-shipped for most applications.
- At 112 oz (7 lbs), it's the lightest 7.62×39 rifle in this lineup, and the AR-15 ergonomics mean the entire AR accessory ecosystem applies: stocks, grips, triggers, and lights all install without modification.
- Accepts standard AK-pattern magazines — steel, polymer, and drum mags all fit. Ships with a Magpul AK PMAG. Most AR-based 7.62×39 platforms use proprietary mags; the Mk47 keeps you in the cheap, plentiful AK mag ecosystem.
- No iron sights are included. The Zastava ZPAP M70 and PSA AK-103 both ship with usable iron sights; the Mk47 needs an optic to be complete, adding to the day-one cost.
- Direct-impingement gas operation is less proven in this caliber than the long-stroke piston designs used in AK-pattern rifles. The Zastava ZPAP M70 and other AKs have decades of documented reliability data; the Mk47 has a shorter track record and some owners note it benefits from confirming gas system function with different ammunition, particularly steel-cased surplus.

Frequently Asked Questions
Does the CMMG Mk47 accept standard AK magazines?
Yes. Unlike most AR-based 7.62×39 platforms, which use proprietary mags fit to AR-15 magwell dimensions, the Mk47 was designed around the standard AK-pattern magazine. CMMG's production team has stated this was an intentional decision because AK mags work reliably with the tapered 7.62×39 case. The rifle ships with a 30-round Magpul AK PMAG and accepts steel surplus AK mags, polymer AK PMAGs, and AK drum mags. That keeps you in the cheap, plentiful AK magazine ecosystem rather than buying single-source proprietary mags. The Mk47 does not accept 5.56 STANAG magazines — those are a different shape and cartridge.
Do I need to buy an optic with the CMMG Mk47?
Yes, plan for it at purchase. The Mk47 ships with no iron sights — front or rear. The M-LOK handguard and Picatinny top rail are ready for any standard AR-compatible red dot or scope, but you'll need something on there before the rifle is usable. A basic fixed-power or red dot runs $100-300; budget accordingly.
Is the CMMG Mk47 reliable with surplus 7.62×39 ammunition?
Owners report reliable function with standard commercial 123gr FMJ loads. Surplus steel-cased ammunition is where more variable reports come in — the direct-impingement gas system can be sensitive to the pressure variations in older or inconsistent surplus ammo. Stick to commercial brass-cased loads initially, and if you plan to run steel-cased surplus, owners suggest confirming function with at least 100 rounds before relying on it. An adjustable gas block is a common owner addition if you plan to run mixed-pressure surplus regularly.
