Getting a red dot sight for your Marlin 336 makes a lot of sense. The 336 is a legendary, classic level rifle—but one of the first to easily incorporate a scope mount. Inside 100 to 200 yards, it absolutely rocks, and that fact makes it the perfect host for a red dot optic. Which red dots, though? Let’s look at some of our favorites.

These are our recommendations for the 4 best Marlin 336 red dot sights on the market:

The BSA 30mm Red Dot Sight

The BSA 30mm red dot is an awesome and affordable little optic. BSA has been around for a very long time, and they are well known for affordable optics, designed more or less for hunting. The NSA 30mm red dot optic is simple and mounts to any standard scope rail. If you’ve never used a red dot scope, the BSA is a perfect one to start with. The BSA red dot scope features a 5 MOA red dot, and it comes with 11 different brightness settings.

The BSA 30mm red dot sports an integrated sunshade that helps reduce glare and keeps your own reflective signature down. The BSA red dot is superbly easy to use and can be zeroed very quickly and very easily. It’s simplistic and perfect for beginners. Most Marlin 336s are in .30-30, which is a solid deer hunting caliber, and the BSA is perfect for deer hunting.

The 5 MOA reticle is quick enough to catch with your eyes but small and precise enough for longer range shooting. The Marlin 336 and the BSA are a deer hunting team made in heaven. The BSA is easy to use and is truly one of the best Marlin 336 red dot sights for the money.

Sig Sauer Romeo 5 Red Dot Sight

The Sig Sauer Romeo 5 is a very modern red dot optic, and I doubt Sig would ever plan for the Sig Sauer Romeo 5 to be on an old-school lever action rifle. However, they are a well-made match. The Romeo 5 is a compact red dot optic that comes with both a low and high mount and the low mount is best suited for the Marlin 336. The higher mount is an option if you prefer a higher chin style hold.

The purpose of lever action guns is their combination of rapid-fire ability and hard-hitting power. The Marlin .30-30 is no different—it’s built to be an easy-to-use, rapid-fire weapon. This means the lighter, the better, and the Romeo 5 is a robust but lightweight optic that’s perfect for rapid fire, close engagements.

The Romeo 5 comes with 8 daylight settings and 2-night vision settings. The dot is 2 MOA in size and is extremely crisp and clear when you are getting a solid sight picture. The Romeo 5 uses the MOTAC system. This is the motion activated illumination design and basically it auto turns on the optic whenever it is moved. This makes it perfect for hunting. When at rest in the tree stand, the optic can preserve battery, and when it comes time to take a shot you’ll have your reticle up and ready.

Burris Fastfire 3 Red Dot Sight

The Burris Fastfire 3 is a miniature red dot that rides nice and low on the Marlin 336 rifle. This makes it perfect for a comfortable and natural cheek weld. The Burris Fastfire 3 comes into two models, and this particular model features a 3 MOA red dot. This model is best suited for rifles like the Marlin 336. The dot is small but bright and easy to see. The little dot is quite crisp and clear and makes the Marlin 336 a quick and precise shooter.

The Burris Fastfire 3 (see full specs) comes with a ruggedized hood system that makes it easier for the Burris Fastfire 3 a bit stronger and more durable. The Burris Fastfire 3 is a natural optic’s choice for a lever action gun, and the Burris Fastfire 3 is a sharp little shooter. The optic feature three different brightness settings as well as an auto adjustment setting. This auto adjustment setting allows the optic to adjust to the situation around you.

The Burris Fastfire 3 comes with a Picatinny rail mount as well, so it’s a quick and natural adaption to the Marlin 336. The Fastfire 3 is a small, but robust optic well suited for hunting at close to intermediate ranges. This should be on anyone’s list of the best red dot sight for Marlin 336 rifles.

Holosun HS510C Red Dot Sight

The Holosun brand is growing and growing very fast in the United States. Although these optics are imported, they have a solid reputation as hunting and competition optics. This specific model is a holographic red dot sight that rocks a very versatile and dynamic reticle.

The reticle (see full specs) has a 2 MOA dot in the center and is surrounded by a 65 MOA open ring. This combination makes it easy to shoot targets both near and far--far being relative to the Marlin 336 in .30-30 and meaning out to 200 yards.

The 2 MOA dot is great for proper shot placement at extended ranges. The 65 MOA ring is better suited for close-quarters use, especially when it comes to brush hunting. When brush hunting, you have to be able to shoot fast but accurately. The 65 MOA ring is much faster to pick up with the eye and at close range is quick and easy to get on target with.

The Holosun HS510C runs off of a single CR2032 battery and will last for 50,000 hours. The HS510C has a backup solar powered option as well. The optic itself even sports a titanium-alloyed, shock-resistant hood. For the price, it’s very hard to find a better red dot sight for your Marlin 336.

Catching a Marlin . . . Red Dot Sight, That Is

A Marlin 336 is an excellent, hard-hitting, and reliable rifle. It needs an optic that is just as hard-hitting and just as reliable. The 336 is a rifle designed to be used out to 200 to 300 yards, and hunting is commonly done at under 200 yards. Pairing the right red dot sight with your Marlin 336 is incredibly important—and will make the perfect combo in lever-action firepower and accuracy. Good luck!
