[ARCHIVED THREAD] - FSP or Carbine cutout rails

Posted: 7/22/2014 6:00:07 PM EDT

looking for a semi drop in carbine rail.

so far it leads me to the MI 12.5" fsp rail and the Centurion C4 fsp rail.

I've got a 10" centurion on my 11.5, but damn...their fsp rail is $330, that is borderline absurd...still I look at it.

I can get the MI one for around $150, but it looks like a thick rail.

Any other options? Anyone have a MI Gen2 2pc FF that can comment on the diameter of the rail?

the C4 rail is smaller and I preferred it over the MI. both mount the same and are solid. buy lightly used gear in the EE to save some money.

save a little longer and get the centurion, you have one, you know how awesome they are

Personally I'd dremel down the FSB and go with a 12" C4 rail and get a Troy flip front sight.

I have a 14.5 and I'm debating doing this. Been seeing 12" C4 on EE for around $200.

I've got other non fsb options.

One of the main motivations of this build was a fsb / 14.5 carbine.

This may be unhip, but what about a Daniel Defense 9.5 FSB rail? They sell for next to nothing these days and are rock solid.

I put the DD RIS II FSB on my 14.5" upper. I dig it.

All the photos I've seen, they look very good. I've been meaning to swap out my KAC RAS for one, I just haven't have the motivation to mess with that rifle as of late. It seems my SPR gets all the "upgrade" attention these days.

I think after shooting this morning, I've decided to just chop the FSB and use my 2nd 10" C4 rail on this upper.

I've already got it and I can set it up like my 11.5, so everything is the same but barrel length.

Thanks a million for the pic Stickman!!!! I have been wanting to see how that looked on a 16" for awhile and you just sold me that rail with your picture buddy!!! I have a question for ya though do you think it will be very front heavy with a SOCOM profile barrel?
