12:00 rail sizing

JP Enterprises Tactical Rail Kit Accessories
Quality is good, but figuring out what you need is really confusing. Spend some time on the JP website figuring it out. For the 12:00 position:
JPTR-R Rifle length is 12"
JPTR-M Mid-length is 9"
JPTR-FS FS is typically for the front sight and is 2".
Please remember these are only for the 12:00 position and as far as I know are compatible on all MKIII style including their Signature series. Shorter ones are compatible with longer rails if you want to save a little weight. Please remember that one end is designed to bridge the gap over the barrel nut and does not have a hole for a screw.
There are 4" and 2" that DO NOT fit 12:00, but will mount in ALL other positions. I suggest you find your handguard on the JP website and click through the options in the upper right corner to figure out what you need. Signature series needs a backer plate to fit in the slot. Good luck!
