I would certainly caution him about the money pit that mil sim markers can become. Be sure to mention to him that when he starts wanting to add stuff to his gun he should seriously consider moving to a new gun. For not much more than the cost of a new stock, egrip etc he can move to the Phenom, TM-7, TM-15, M-Tac, Tactical drone etc.
I'm looking at buying a mil-sim marker as well, and my research has lead me to the same conclusion about not upgrading a cheap mil-sim gun, but rather buying a nicer one to upgrade.
I'll probably get a BT-4 Omega, and just keep it stock with a $5 gravity feed hopper, and everything. I'll use that as my gun for playing back or mid, and probably never upgrade it unless the upgrade fits on more than 1 gun that I own. I don't plan to upgrade the hopper because I the next gun I'll buy will probably have a feeder system on it already. When I start wanting to put an e-grip and rip-clip on it, I will simply buy a Tippmann X-7 Phenom, and just use it stock until I have the money to upgrade it. I would rather put money into an X-7 instead of a BT-4. You will never come close to getting your money back out of upping a BT-4, Tippmann blowbacks, etc. Just look at the BST forum.
I think the BT-4 Omega is probably a bit better in some areas than the U.S. Army line by Tippmann. It is probably ever bit as durable, and looks less toy-like in my opinion. It is MUCH cheaper to buy the omega than to buy the stock BT-4 Combat, and put a stock, handle, and shroud on it.
You can buy a BT Omega for $129 just about anywhere. The only thing about a mil-sim marker is that it might be heavy. He might be used to shooting real guns, but running around with them is a different story many times. Also, buying one with a stock on it looks more mil-sim, but I would recommend using a remote coil, which would add another $35 to the total.http://www.ansgear.c...egagunblack.htm
