I have a spikes lower and I'm wanting to use a kreiger barrel probably a 26" barrel

I was wondering what match grade upper parts are out there and the best bang for the buck.  

This is my first build and just looking for advice on internal upper parts i.e. bolt carrier, charging handle, etc.....

Thanks

Blem m4 upper from BCM
Also thats what I would buy personally they clean up well from what I've read. They have m4 feed ramps I don't know if your barrel does or not.

If you're going for a freefloat rail system I'd consider Daniel Defense, or even a monolithic rail upper like LMT, Mega, or VLTOR polylithic uppers. You can get your Krieger machined to match the LMT MRP receiver barrel bolt cuts.  Also a Badger tac-latch charging handle would make it easier with a scope.  Good luck on your build. Sounds like its gonna be a 1 hole group shooter.
