The M400 is just like any other AR. All of those things, including the barrel, can be customized with standard AR parts.Put in order today.
It being a sig other manufacturers barrels probably will not work but what about triggers and sights or scope mounts?
New to accessorizing AR’s.
My M400 has a Centurion BCG in it. (Unless Colt all AR-15s get Centurion BCGs)Not really. I don't know as I've ever seen the m400 marketed as anything other than a traditional DI AR. It has some features that make some of it's parts non-milspec, and thus "proprietary", but the operating bits will all interchange with milspec parts, to my knowledge.
Friend said medium level rifle with nothing special not a bad price.
7 pound trigger but sights first.
Just shot several Alt Cs this weekend with the PA MD-25 on Colt 6920SOCOM, both on and off.Picked up yesterday.
The kicker was the billet lower and upper. That is pricey to up grade.
Thanks Kirk Freeman for the optics and sights info.
Seriously looking at that optic.
Not sure what is on the Springfield, thought is that they should match at least style wise.
