L'Antre Du Dingo checks out the AIMWIN PE330, a compact red dot sight designed to withstand the recoil of actual firearms while being light enough for airsoft enthusiasts. This enclosed optic features an aluminum body and offers three reticle options: a 3 MOA dot, a circle, or a combination of both. It comes with a side-loading battery tray, saving you from the headache of re-zeroing your sight every time you need to swap out a CR1620 battery.
