ARD lens cap for your Sig Romeo MSR red dot sight that protects the glass from bumps, BBs, and finger smudges. Protects the user from the light reflection off of the front glass. Easy to see through and easy to print.
- Make sure you understand how to use TPU filaments with your printer, I highly recommend using a retraction test to dial settings to prevent excessive stringing blocking your sight picture.
- Note: BB protection is theoretical - better than raw doggin it, but trust at your own risk.
