All carbine length gas systems, not just the M4, will run at higher pressures. This may or may not affect functioning in a particular carbine depending on all kinds of factors.
There are any number of gadgets designed to reduce the cyclic rate or gas pressure in a carbine length gas system. Most of them are unneccessary in your normal 16" semi-auto carbine, though a heavy-duty extractor spring or O-ring extractor insert can provide some cheap insurance.
Problems with the carbine length gas systems are more apparent in full-auto or suppressed guns (or guns with both) than they are in semi-auto 16" guns.
