The Classic Army M24 is an excellent replica. It features a one piece metal / fluted barrel that is very heavy and realistic.
Also available are drop-in upgrade kits and a gas conversion kit that make the M24 a very attractive choice.
If you opt for an advanced cylinder upgrade kit, you can then shoot a heavier BB (0.30g) and gain even more accuracy. Taking out your opponent with one shot is what the M24 is all about.
**Externally the fit, finish, and feel are second to none on the M24, however, the internal components need alot of "TLC" and constant work to maintain a skirmish level. Be warned, this is very nice and realistic rifle, but constant maintenance must be present for this to be a reliable skirmish rifle. Warranty only thru Classic Army (Spartan Imports).
