The correct mount sets your red dot at the right height for a fast, heads-up sight picture and a solid return to zero. We stock red dot sight mounts, risers and adapter plates — absolute and lower-1/3 co-witness, low, 1.93 inch and taller heights, in fixed and quick-detach forms — from UK stock.
What these fit. The rifle mounts and risers here are Picatinny and Weaver pattern, which is what an AR-pattern flat-top upper, a straight-pull and most modern rimfire rails carry. We do not stock an 11 mm dovetail adapter — if your .22 sporter or air rifle has a dovetail receiver, read our 11 mm dovetail article first. The pistol adapter plates are footprint-specific rather than rail-mounted: match the plate to your slide cut and your optic using the footprint compatibility chart.
Need an optic too? Browse red dot sights, rifle dot sights and pistol dot sights — red dot sights under £300 covers the money. For magnified optics, see rifle scope mounts. Pick a height with the mount height chart. Mount brands include American Defense Mfg and Holosun. Everything ships from UK stock with no import fees.
Frequently Asked Questions
What height mount for a straight-pull or AR-pattern rifle?
A lower-1/3 co-witness or a 1.93 in (49 mm) mount gives a comfortable, heads-up position; absolute co-witness lines the dot up with iron sights. Both suit practical and service rifle work.
Do I need an adapter plate?
If your optic's footprint does not match your slide cut, an adapter plate bridges the two — check both footprints before ordering. Rifle mounts do not need a plate, only a Picatinny or Weaver rail.
Can I use a red dot for deer stalking?
The rules on permitted sighting equipment for deer differ between the countries of the UK. Our article on using a red dot sight for deer stalking in the UK sets out the position — read it before you buy for that purpose.
