Best Optics for Practical Shotgun

For UK practical shotgun, the best optic is a rugged 1x red dot with a circle-dot reticle on a low receiver mount. From our range, that means the Holosun HS510C, or the enclosed Holosun AEMS EVO if you shoot in foul weather. The Primary Arms SLx 1X MicroPrismT is the choice for shooters with astigmatism. Before you buy, check your division: under IPSC shotgun rules, optics are allowed in Open and Modified but not in Standard or Standard Manual.

Practical shotgun runs a pump or semi-automatic shotgun through courses of fire against paper, poppers and plates, from arm's length out to slug distances, with reloads against the clock. The UKPSA describes itself as having led the development of the discipline (UKPSA). It is also very hard on equipment. Everything named below is in our shotgun red dot sights collection.

Check your division first

IPSC's division tables are explicit. Optical or electronic sights are permitted in Open and Modified, and not permitted in Standard or Standard Manual, where aftermarket open sights are allowed instead. The rules also define optical or electronic sights as "aiming devices (including flashlights) fitted to a firearm which use electronic circuitry and/or lenses", and make the Range Master the final authority on classification (IPSC Shotgun Rules, January 2024). UKPSA matches run under IPSC rules, but check the current rulebook and any UK interpretations before building a gun around a division.

Why a dot suits this discipline

• You shoot with both eyes open and the gun moving. A 1x optic with unlimited eye relief lets you drive the gun to the target and shoot as the dot arrives, with no head position to find first.
• Target size varies enormously. A circle-dot reticle handles that: a big circle for close targets where you can afford to be coarse, and a small dot for a plate at slug distance.
• Loads change within a stage. Buckshot patterns and slugs group, and a reticle that gives you both references at once is doing real work.

The counterweight is recoil. Shotgun recoil throws the optic rearward and then forward again as the gun returns, and the sights that cope are a short list. We cover that in best red dot sights for shotguns; this guide is about the discipline.

The circle-dot case, with numbers

The HS510C's Multi-Reticle System switches between a 2 MOA dot alone, a 65 MOA circle alone, and both together. At 10 m (11 yd), the 65 MOA circle spans about 19 cm; at 25 m, about 47 cm. At practical shotgun distances it frames the target rather than covering it, and the eye centres it without having to search for a small dot. When you reach the slug target at the back of the stage, switch to the dot alone. At 2 MOA it covers about 58 mm at 100 m, so you can shoot the slug like a rifle. Our red dot size chart sets out coverage at distance.

Open, enclosed or etched

The HS510C is an open reflex with a titanium hood over the emitter. It is rated IP67 and tested to 5,000G of vibration, with Solar Failsafe supplementing the CR2032 and Shake Awake switching it on when the gun moves.

The AEMS EVO is enclosed: the emitter sits behind glass at both ends, so rain, mud and residue cannot block it. It has the same 2 MOA / 65 MOA reticle system and is rated IPX8. That makes it the choice for a wet winter league.

The third option is a prism. The SLx 1X MicroPrismT is 63 mm (2.48 in) long and 156 g (5.5 oz), close to micro-dot size. Its reticle is etched into the glass rather than projected, so it stays sharp for shooters with astigmatism and remains usable with the illumination off or the battery flat. It uses the H1/T1 micro-dot footprint. See prism scopes explained.

Getting it onto the gun

• The gun has a receiver Picatinny rail. Most modern tactical and optics-ready shotguns do, and everything in the table fits directly. The HS510C brings its own quick-detach mount.
• The gun has only a ventilated rib. A rib-clamp mount grips the rib and carries a compact dot or short rail without drilling. We don't currently stock rib mounts, so source one separately and measure your rib width first.

Go low. A shotgun is a cheek-down gun and its comb was shaped around a bead, so a tall mount fights the gunfit you already have. The red dot mount height chart lists the common heights.

The light, and why the forend matters

Low-light stages want a light on the gun, and a shotgun is an awkward host: the forend moves, and anything clamped to the magazine tube gets in the way of reloads. The Streamlight TL-Racker replaces the forend entirely, with an ambidextrous momentary or constant-on switch. Streamlight quotes 1,000 lumens and 20,000 cd for a 283 m beam, and 1.5 hours on two CR123As, rated IPX7 (Streamlight TL-Racker).

Fit is host-specific: choose the Mossberg 500/590 version (69600), the Remington 870 version (69601) or the Mossberg 590 Shockwave version (69602). Streamlight excludes the Remington 870 Express Supermag. Remember IPSC's rule that a light counts as an electronic sight when you choose a division.

Zeroing for two loads

Because you shoot buckshot and slugs through the same sight, zeroing has two halves. Zero the centre dot with slugs at 25 to 50 m first, because that is the shot that needs precision. Then pattern your buckshot against the circle at 10, 15 and 25 m, and note what the circle means for your gun and load. Barrel, choke and cartridge all change it, and the pattern your own gun produces is the one that matters.

Frequently asked questions

Can I use a red dot in every practical shotgun division?

No. IPSC permits optical or electronic sights in Open and Modified, not in Standard or Standard Manual. Check the current rulebook before you build the gun.

What size dot is best for practical shotgun?

A circle-dot. The 65 MOA circle on the HS510C or AEMS EVO gives fast close-range pick-up, and the 2 MOA centre dot gives precision for slug targets.

Should the optic go on the receiver or the rib?

The receiver, whenever the gun has a rail there. It is closer to the eye and more rigid. Rib mounting is for guns with no receiver rail.

Is a magnifier worth it on a shotgun?

Rarely, because speed governs this discipline. If the same optic also goes on a carbine, the HS510C and HM3X 3x magnifier combo bundles the pair; see choosing a red dot magnifier.
