OZ,
Heres what I bought from tacticalgears.com
I melted the lower with 350 rounds (freakin took forever to get that crap off my rifle!!!)
I kept the upper which is one of the best buys I could have ever made. Heat dissipates really fast. You'd think it'd be worse with steel, but since its so perforated, heat dissipation is super quick!!! I remember the original woods almost caught on fire on me!!! HEE HEE HEE!! And they stayed hot longer than this upper!! I just wish I could have bought 'JUST' that. Not the whole piece of crap package.
Anyway...the second thing to bonk on me was the vert! It got hot and FELL OFF!! Partly because the bolt that held it in place was so freakin small that it looked like a needle!!!
I solved that by adding a bigger bolt and some side plates to compress the whole assembly!!!
But goddamn it I wish I could buy something that works for once. I hate this endless modification bullshit!!! Thats partly why I am going to go into the gun parts business myself!!! Frickin make something good dammit!!!
I would suggest looking for a sturdy vert from some 'other' company that will accept weaver/picatinny rail. You'd be better off that way.
As far as the rail goes I just used the one from the crap that I bought from that CRAPPY company! It has slots every 1/2" or so. Really flexible. Its aluminum so weight isnt an issue.
What may be an issue with Chris is that he will lose his cleaning rod. Theres NO way to get around that. believe me I tried. The clearance is so freakin tight that the nuts just cant be milled down without losing them altogether!!! Sorry on that one!
The K-var synth stocks have really nice heat shields in them too, making it even tighter in that area!!
p.s. Check out my new post in the hometown boards....named some reactives after you!! HAHAHAH!!
