To distinguish it as a replica, I believe so.

Just for the record, do actual BB guns require a red tip down there?

no actual bb guns don't require a red tip in the states

I think it also depends on what state that you are in, perhaps not all states require an orange tip. But that's just a theory.

yeah the flash hider doesnt come off, the barrel does though. like i said, by far the nicest body to any AEG every IMO, and G&G is known for that, however the internals suck.

Thanks for the info. I am new to airsoft and this forum. I just purchased a TM G36C and I'm impressed with how detailed it is. I was into real guns but you pay so much and get so little. What I mean by that is look at the USC, how can you make such a nice looking piece like the UMP look like a toy water pistol. Leave it to H&K to make the USC. They could have at the very least given us a black gun! Then I was going to buy a Ps90 they are selling for $1999.00 US. Do you realize that law inforcement is paying about $850.00US for a UMP and the public is paying $1200.00 for a USC. sorry for going on.

lol, yeah law enforcement agencies, government and private protection buy the guns, and buy them at there worth, where civilans actully arent suposed to have them at all, and can mark them up.
