best tbb on a budget? also i will be buying 4/5 off these 1 for my m4 1 for an mp5 1 for my 226 another for my 417 and finally one for a sniper/bolt acion rifle
With PDi the shorter the barrel,the lower the price. I'd get PDi for the 226 and MP5,Madbull should suffice for the 417 and M4,this is one a price opinion though. It depends how you sue the guns.
