I will need the range of the IR to be somewhere in the neighborhood of 30-50+ feet.

Too far for an IR LED, you might have to go for lasers.

I will only be using 1 gun so I won't need to worry about detecting different frequencies.

I don't think you understand about detecting different frequencies, one sensor detects one frequency, that's it.

If it's not too far then it certainly is borderline.  How far does your TV remote reliably work?

Adafruit sells a device that transmits only the "OFF" code for every tv code known. You could use that and a photo... what a waste... 

Actually you might use this as a starting point since the TV-B-Gone (http://www.adafruit.com/products/73) is fairly high powered in order to get enough range so that the user does not get assassinated by his victims.  I would salvage the receiver out of an old TV, DVD player, etc.

If it is a shooting game you need a colomated IR beam otherwise there is no game, just point in the general direction.

the TV B gone is good for several hundred feet... according to Adafruit...
