HASTA Lens Protector for 20mm Picatinny Rails

  • Fits on 20mm RIS / RAS Rails
  • Cheaper than a new sight
  • Clear & Yellow Option

This lens protector is a must-have product for any Airsoft Skirmisher who intends to play in a CQB environment, protecting your sights and scopes from being shot out by stray BB. Guess what's cheaper: A new sight or lens protector? 

Ships with peel-off protective film so it arrives perfectly clear when you attach it to your RIF

Full description


The mount itself is constructed from alloy, making it durable and hard-wearing, with a polymer Lens protection section that is clear and can easily see through no matter the conditions.

The lens protector can quickly and easily be attached to any weapon which features a 20mm RIS / RAS rail, is placed in front of the scope, and is easily affixed thanks to its screw-less design meaning the item can be hand fitted quickly in the safe zone if required.

The set comes with one unit wholly built and comes packaged with an additional two covers which can be easily replaced if your first one becomes broken or damaged. To replace the lens cover simply use the provided Allen key to remove the two front bolts, swap out the plate, then screw it back into place.

This product is a must-have for those unlucky Airsoft Skirmishers who seem to get their sights and scopes shot out the moment they step into a CQB environment, or for those who have dipped serious money into a high-quality scope and would prefer a cheap piece of plastic to get shot out rather than an expensive objective lens.


  • Protects sights and scopes from incoming BBs
  • Designed to fit on 20mm RIS / RAS rails
  • It can be flipped up / down depending on your application
  • Tool-less fitting
  • Allen Key is included for switching Perspex protectors
  • 5cm x7cm protective area
  • Sits 2mm above the rail

Package Includes:

  • Lens Protector 20mm RIS / RAS Adaptor
  • Perspex Lens Protectors x2
  • Allen Key

Special Instructions

If you never intend to flip down the sight and prefer to permanently have your sight protected you can place the protector on back to front. Using the protector back to front will allow the protector to be knocked over slightly when shot, absorbing some of the impact energy, to improve the lifespan of each protective lens.
