The SIG/Sauer catalog continues to expand, now with this new carbon fiber-enhanced M400 and its piston-driven 516 counterpart (not shown.) The free-floating handguard and A2-length fixed buttstock are both fashioned from the cool shiny black stuff . . .
Yes, $2100 is real money, but street pricing should bring this down to the ‘maybe someday’ price category. Which isn’t bad for a SIG, after all.
You can instantly tell that the carbon fiber M400 is lighter than a standard AR, but exactly how much lightness does that carbon fiber (and your extra dollars) buy you?
Good question: the product tag doesn’t say. The SIG rep didn’t know. And I don’t generally bring my own product scale to the SHOT Show.
SIG is also shipping M400s and 516s with carbon fore-ends and non-carbon telescoping stocks, but they’re perceptibly heavier than the all-carbon stocked versions. Which seems fairly pointless to me, but YMMV.
