Home Forums Hunting & Shooting AR and Tactical Rifles Guys looking at a SIG556 Classic have a ?

The assumption that a piston driven gun like the Sig 556 could be more reliable than the AR platform comes from the comparison of the AK 47 and AR.

The piston driven SIG 556 does run cooler and cleaner in the breach area which may give it an advantage (time will tell).

However, the Sig 556 (and other new piston rifles) are built much tighter than the AK 47. There is less room for debris/dirt/sand to get into the action of these guns but its also less room for it to get back out.

I have read more that a couple of reviews on the Sig saying it would be fine for urban combat but would not fare very well in harsh operating climates.

The AK shines for its reliability because of its loose operating tolerances combined with its piston driven system.

IMO if you are looking for reliability there is no advantage to these new tight tolerance piston guns over the AR platform.

If you want a piston gun get a good AK IMO.

My pick is still the DI AR platform from a top tier company.
