Booligan got an affordable red dot sight made for real steel rifles to review... "I was impressed when I first pulled the HD7 out of the box, and I'm still impressed with it now. The thing is extremely well designed and built, and the fact that it's backed up with a US based limited lifetime warranty is just the icing on the cake. The thing is a high end optic, and has a relatively high end price, especially when compared with airsoft specific optics, however, if you're looking for something that will take the recoil forces of a GBBR or recoil shock AEG without falling apart, or if you want an optic for your real rifle, the HD7 should absolutely be considered. At the current market price of $190 or so, it is a really hard deal to pass up."
