Chestnut Mountain OKP-7 Red Dot: Russian Reflex Reborn

Chestnut Mountain Manufacturing unveiled a faithful reproduction of the Russian OKP-7 reflex sight at GunCon 2026 on June 26, 2026, priced at $319.95 with a lifetime warranty. The reveal aimed at a niche the AK aftermarket has been trying to fill for two decades, an OKP-7 built strong enough to live on a real 7.62x39 receiver rather than the airsoft replicas and Aliexpress clones that dominate every Google result.

Chestnut Mountain ships four configurations at launch. Buyers choose between Picatinny and AK side-mount dovetail interfaces, then between the CETKA 1 T-post (in either a dual red-and-green reticle or a green-only version) and the CETKA 2 circle-dot reticle. Every variant carries the same $319.95 price and the same lifetime warranty. The product page lists every configuration as sold out at launch, with batches released periodically as production runs land.

The OKP-7 is one of several launches that hit this week from GunCon 2026 in Niles, Ohio. For broader coverage of the show, see our reporting on the Inland Model 1910 Maxim suppressor launch from the same event.

The OKP-7 is the optic that lives on the front of every modernized Russian rifle in service photos from the late Soviet era forward. It is a low-magnification reflex sight designed for issue-grade AK-74 and AKM platforms, mounted on the standard Warsaw Pact side rail that has been welded to the left side of stamped and milled AK receivers since the 1970s. The optic became a visual shorthand for an Eastern Bloc rifle that had been pulled out of the rack and brought into the red-dot era.

US buyers who wanted an OKP-7 on a real rifle have spent twenty years choosing between two bad options. The first was an airsoft replica with a plastic body and an acrylic window, which would not survive recoil from a hot 7.62x39 round. The second was a direct Russian import that became impossible to source after sanctions in 2014 and 2022 cut off the supply chain. The Chestnut Mountain reproduction is the first option in years that uses cast aluminum and coated glass, holds zero under live fire, and ships from a US business with a warranty rather than from a Chinese wholesaler with none. For broader context on building a modern AK, see our AK-47 accessories and upgrades guide.

The Chestnut Mountain OKP-7 is built around a cast aluminum housing with a coated glass lens and 1 MOA windage and elevation adjustments. Reticle brightness adjusts automatically to ambient light, which means there is no manual brightness knob and no off setting. The optic powers on when the LR44 battery makes contact and stays on as long as the battery has charge. Chestnut Mountain rates the LR44 for 40 hours of continuous use, which is short by modern Aimpoint standards but consistent with the original Soviet-era design that the reproduction is built to honor.

The two reticle options track the two roles a Russian soldier would have used the original OKP-7 in. The CETKA 1 T-post is the issue reticle, a vertical post topped by a horizontal crossbar that the shooter places below the target at carbine ranges. It ships in either a dual red-and-green configuration that lets the shooter pick a color based on light conditions or a single green-only version for buyers who only want the green dot. The CETKA 2 is a circle-dot reticle in red, a more conventional pattern for shooters who learned on a modern Aimpoint Comp or Eotech. Both reticles are etched and visible without power, though the illumination is what makes them usable in low light. Each optic ships with a translated copy of the original Russian manual.

The dovetail variant is the cleanest install on a traditional stamped or milled AK receiver. The Warsaw Pact side rail is already there from the factory on most modern imports, including the WASR-10, the PSA AK-103, the KR-103, and the Riley Defense and Pioneer Arms stamped builds. The OKP-7 clamps directly onto that rail, repeats zero when removed and reinstalled, and sits high enough above the receiver to clear the rear sight leaf without a riser. For anyone running a factory Russian, Bulgarian, or Romanian AK with the side rail intact, this is the install Chestnut Mountain engineered around.

The Picatinny variant opens the OKP-7 up to modern AK builds that have abandoned the side rail. That includes 5.56 AK pistols with optic-mount dust covers, custom receivers from Sharps Bros and Childers Guns, and builds with an RS Regulate or Midwest Industries side-rail-to-Picatinny adapter already in place. It also lets the OKP-7 land on hosts outside the AK family. A Galil ACE with a top rail, a CZ Bren 2, or even a 5.56 AR pistol could take the Picatinny version. The optic loses some of its retro meaning on a non-AK host, but the price-to-feature ratio still competes with budget red dots in that price tier. For broader options on the AK platform, browse the optic catalog or use the rifle builder to spec out a complete AK build around it.

One thing to note. The OKP-7 is an open-emitter reflex sight, with the LED visible inside the housing rather than sealed behind a second pane of glass. AK rifles run a hotter gas system than a direct-impingement AR, and that gas blasts straight back at any optic riding above the receiver. The original Russian design accepted that trade-off because the side rail mount put the optic far enough above the gas tube to keep most of the carbon clear. The reproduction is identical in geometry. Expect the lens to need wiping after long range sessions on a gas-piston host. For a closer look at the open-versus-enclosed trade-off and which optics survive AKs and shotguns, see our enclosed-emitter red dot guide.

The Chestnut Mountain OKP-7 sits at $319.95, a price band that puts real pressure on the existing landscape. The airsoft and unbranded clones on Amazon and eBay run $40 to $90, but those products are explicitly marketed as non-firing replicas with plastic housings and zero warranty. The genuine Russian imports, when anyone can find one, change hands for $400 to $800 on auction sites with no recourse if the optic fails. Chestnut Mountain threads the needle by pricing slightly above the replica tier and well below the import tier, and covering the gap with a real lifetime warranty backed by a US business.

For comparison, an Aimpoint PRO sits at $499, a Holosun AEMS Core X2 at $353, and a Vortex Strikefire II at $239. The Chestnut Mountain OKP-7 lands in the middle of that modern field, but it competes on aesthetic and authenticity rather than runtime or durability. A buyer paying $319.95 for an OKP-7 is paying for the period look and the side-rail-native install, not for a 50,000-hour Aimpoint replacement. The lifetime warranty makes that trade-off honest. For a side-by-side of how it stacks against modern red dots on AR-15 hosts, see our best red dot for AR-15 guide.

The Chestnut Mountain OKP-7 is the first reproduction of the Russian Army's standard-issue AK reflex sight that an American buyer can put on a real rifle without choosing between a polymer airsoft toy and a $700 Bulgarian-import gamble. It is not a duty-grade optic, and Chestnut Mountain has not pitched it as one. It is a cast aluminum, coated glass, side-rail-native reflex sight with 1 MOA adjustments, automatic brightness, an LR44 battery, and a US-backed lifetime warranty at $319.95. For the AK collector, the Eastern Bloc retro builder, or the shooter who wants the period look on a modernized AKM, that is the first time the math has worked.

The remaining question is supply. Every variant was sold out within hours of the GunCon 2026 launch, and Chestnut Mountain has been clear that batches will ship periodically rather than continuously through the first months of production. If the OKP-7 is on the build list, watch the product page and pick a variant the moment a restock lands.
