Theres an en episode of future weapons where the host demonstrates the HK416 at the companies range. They stuff it in a box of sand and then take it out, shake it off and shoot it full auto for about 30 rds. Then they stick it in a tub of water and do the same.
Looks cool, but I have no idea if its really that great. Regardless I don’t like the idea of depending on a foreign company for our main battle rifle.
FN makes the SAW, and our main handgun is a Baretta. But I know at least the Baretta is made in the US (which, BTW, caused some quality issues).
that show is fun to watch and not bad if one realizes it is one big infomercial. there you can say cut and re shoot in a battle not as easy.
It probably does a better job at sealing its critical parts from the dirt than the M-4. Colt may be able to do minor design changes to the M-4 that could make it comparable to the HK416 at protecting it from the elements.
