Due to the Iraq experience there has been a bit of a re-think about the 5.56mm x 45mm NATO round - due to it's apparent lack of penetration and stopping power.
The vogue is now for large calibres again (du-oh!) - and while the initial stop-gap was the trusty 7.62mm (with many US troops preferring to use modernized and tactical modded M14s) - there have been two new calibres developed which are said to be better - balistically - than the old 7.62mm x 51mm NATO round.
These are the 6.8mm Remington and the 6.5mm Grendal.
Both of the calibres have been accompanied by 'new' versions of the M16/M4 design. The 6.5 Grendal, in fact, being a direct conversion of existing M16/M4 stock, with new receiver and top deck. The 8.6mm calibre is being championed by the famous Barrett company.
I would like to see these included in a new gun mod as they reflect up-to-date thinking about military rifles - superceeding even the G36/SCAR rifles that are the vogue in mods.
