Our military adopting the Grendel?

[bwaites]

an old adage I heard years ago still rings true
"the enemies weapons never jams"

On my earlier statement about redesigning the weapon around the Cartridge. The question comes to mind of the Remington/DPMS answer to the .30 RAR they used a modified Bolt and Barrel extentsion humm I don't hear many compliants from their users as few as they are, Food for thought?

If you strengthen the bolt, the barrel extension becomes the issue. Strengthen the barrel extension, and another point becomes the weak point. Keep that up, and eventually you end up with a 15-20 pound Carbine. The .30 RAR is a hunting rifle, with inferior ballistics. Bigger bolt, but very limited real options as far as bullet options that work from mags.

Bolts are exspendables, and when a bolt goes, there is really very little damage to the rifle. Maybe a mag is damaged, but other than that, no real damage, generally. It acts like a circuit breaker in an electrical system, and prevents further damage.

I know LRRPF52 thinks that improving or increasing bolt size might be helpful, and I certainly recognize his significantly higher level of experience than my own, but it seems like we might be asking the wrong question when it relates to the AR. The AR works, we actually have very few bolt failures at this stage, and those we have are not catastrophic. I'm not sure that is the right move.
