Optics & Sight Mounting

Buy the gun, optic and mounts from us and we'll mount and boresight it for free. Bring us your own and it's twenty bucks. Either way it's done with the right tools, the right torque, and no guesswork.

What It Costs

  • Free — buy the gun, the optic and the mounts from us, and mounting and boresighting are on the house.
  • $20 — mounting and boresighting on equipment you bring in.
  • $10 — boresighting only.
One honest limit: your firearm must be factory-ready to accept a mount system. We do not drill and tap.

Done Right Means…

  • Correct torque on every screw — snug by feel is how dots come loose and scopes shift. We use torque specs, not guesswork.
  • Threadlocker where it belongs (and not where it doesn't).
  • Proper base and ring alignment so your scope isn't stressed in the rings.
  • Boresighting so your first range trip starts on paper — remember, boresighting gets you close; final zero is confirmed by you, at the range, with your ammunition.

Red Dots: Getting The Footprint Right

Optics-ready pistols cut their slides for specific footprints — Trijicon RMR, Holosun K, Shield RMSc and others — and the wrong dot simply won't bolt to the wrong slide, or worse, almost will. Bring the pistol (unloaded, action open) or just tell us the model, and we'll match the dot, the plate and the screws before you spend a dime.

What We Stock

We keep Holosun, Vortex and Trijicon red and green dot sights in the shop — including Holosun's popular carry-size 407K/507K series and EPS Carry, priced well below MSRP. Scopes, rings and bases for rifles too. If we don't have it in the case, the online store's optics section ships to the shop for pickup.

Straight Answers

Common Questions

Is optic mounting really free?

Yes — buy the gun, the optic and the mounts from us and we mount and boresight it at no charge. On your own equipment it's $20 for mounting and boresighting, or $10 for boresighting only.

Can you drill and tap my receiver?

No — the firearm must be factory-ready to accept a scope mount system. We do not drill and tap.

Which red dot fits my pistol?

It depends on your slide's footprint — RMR, Holosun K, RMSc and others are not interchangeable. Tell us your pistol model at the counter and we'll match the correct optic, plate and screws before you buy anything.

Do you zero the optic for me?

We boresight it, which puts you on paper at the range. Final zero should be confirmed by you, with your ammunition, at your distance — every load shoots a little differently.

What red dot brands do you carry?

Holosun, Vortex and Trijicon red and green dot sights, in the shop, priced well below MSRP — including the carry-size Holosun 407K/507K series and EPS Carry. The online store carries the full catalogs.

My scope keeps shifting — can you fix it?

Bring it in. Nine times out of ten it's rings torqued wrong or a stressed tube — we'll remount it properly with correct torque and alignment.
