The CS Vengeance 5.1 + RDS combines the visually distinctive Vengeance slide cuts with a factory-matched red dot optic. The slide is specifically cut to accept the included optic — it ships mounted and ready to run without any additional fitting required. Mechanics are identical to the standard 5.1 RDS; the difference is purely the external CS Vengeance slide profile.
For players who prefer the modern Vengeance aesthetic over the classic Hi-Capa silhouette and want a dot-ready pistol out of the box, this is the correct listing.

Before you buy — essentials
| Item | Notes |
|---|---|
| Green gas | Nuprol 2.0 recommended for reliable UK temperature performance |
| Spare magazines | One mag lasts roughly one engagement — most players carry 3+ |
| 0.25g BBs or heavier | 0.20g is too light for accurate GBB fire — use 0.25g minimum |
| Hi-Capa / 1911 holster | Hi-Capas fit most standard 1911/2011 holsters — note CS Vengeance slide cuts may not suit tight kydex moulds; soft or universal retention holsters are safest |
Common questions
UKARA: All realistic imitation firearms require UKARA or a valid defence. We verify at checkout. To register: play 3 games over 56+ days at Skirmish Wycombe Airsoft.
Magazine compatibility: All Vorsk Hi-Capa pistols use the standard Hi-Capa / 2011 platform — cross-compatible with TM, Army Armament and other Hi-Capa brands across the entire Vorsk range.
HPA conversion: Yes — pair with the AirTac Hi-Capa to M4 HPA adapter for consistent FPS output in cold UK conditions.
CO2: Works but accelerates internal wear. Use a CO2-rated magazine and replace O-rings regularly if you go that route.
Red dot battery: The RDS runs on a small button cell — brightness adjustable, spare battery recommended in your kit.
Iron sights alongside the RDS: The RDS occupies the rear sight cut on the slide — standard iron co-witness is not available. The dot becomes your primary sighting system.
