I saw a Bushnell red dot that looked EXACTLY the same as the EOTECH!

Has anyone seen these Bushnells?  Are they built by EOTECH?

Yes your are correct.

Just keep in mind that the Bushnell holos are not as rugged as the EOTech branded ones.  For general plinking, range use, and competitions it will probably do.  However, if it is for serious work, get an EOTech.

What is the difference?

EOTech 502 and Bushnell Holosight is the same exact unit, what Knightone is saying si to buy a upmarket EOTech such as the 510 or the 550 series.

510, the LE version consist of 511 and512 has different electronics, longer battery life, a protective hood, and a programmable auto shut off of either 4 or 8 hours.

550 military series has all the 510 features plus NV compatibility of eight seperate settings, dive capable to 33ft for 24 hours and 66 ft to an undisclosed time frame.  rubberized buttons instead of the membrane style for better feel with gloves and during dark or waterborne operations.

Hope this helps.

Chen, thanks for the info.  I was wondering about the 502.  I had no idea it was the same as the Bushnell.  That's good to know.  Thanks.  For $15 or $20 more, you might as well just get the 511 model IMHO.
