I plan on swapping out my Magpul rail for a 12-15" rail. I've been looking on various website for ideas and the styles and prices are all over the board. I've been looking at the Troy Alpha rail, Bravo, or MRF. Any other suggestions. I'd like to keep the price at $200 or less if possible.
Seekins Precision is at the top of my list when it comes to rails. I've handled a Fortis before too and likes it a lot. Black Rain make some nice keymods as well and I love the clean sturdy look of Noveskes.
For under $200, I like the way the Troy uses the existing barrel nut after you strip it though. YHM makes some great rails for the money.
I just got a 15" CMMG keymod for my 308, simple style, nothing special but so far so good. They're 5.56 rails are a bit cheaper
What is your intended use for the rifle? Do you need short and light, do you want to have full rails, are you wanting something in keymod? If you've been researching you should be able to refine your search a little more than just by price. How are you wanting to attach the rail? If you want to utilize the delta ring and not some other mode it will also change your options.
A vote for Midwest Industries, here. I've used several of their rails and always found them to be tough as nails, very well made and reasonably priced. Not the first complaint outta me.
The troy rails and midwest industries suggested I personally like, There is one that Diamondback makes I am also a huge fan of! There are so many options out there when it comes to rails and bang for your buck that is for sure.
