Ratings & Reviews
This is a great rail if you have a standard front sight post and don't want to or can't change it out. Installation is super easy. The handguard is sturdy and feels strong but it does flex a bit. Its advertised as a free float but if you don't cut your bayonet lug there is a good chance it will make contact there. If you have longer arms like me the rail gives you a good bit more real estate to grab on to.Also, great service and price from Primary Arms, I get why everyone speaks so highly of these guys!
I have a Bravo Co. 14.5" barrel with a mid length gas system. Since I have a welded flash, it was hard finding a full float, 2 piece mid length extended rail. Not only did I find it in the Troy rail, it's an awesome rail to boot. The diameter is great when shooting for keeping a nice positive grip and feel on the front end. Keeping the delta ring isn't a bad option either as its always best to have the option to go back if needed. Personally, I won't be going back to a drop in system. I couldn't be happier with this Troy battle rail.

a little sharp cuts but pretty easy to put on and use. Just wish they included rail sections with it.
One little fix...
This rail setup is great, installs in minutes and is rock solid. I expect nothing less from Troy. The only little thing I'd change is the rail section covering the bayonet lug/sling point. I'd rather it was smooth like the sides around the gas block/sight. Still I have switched my EDC gun to this setup and love it. Thanks PA!

Cake to install, seems to be rock solid. Comes in on my postal scale at 13.7oz.
Troy Free Float Rail
by Chris Colbert
Very easy to install with a very solid feel. This is great for someone looking for an extended rail who likes a fixed front sight post.
It took me a good while to install this rail. It's a good rail and machined very well. It was slightly frustrating to get on the rifle (took me an hour) but after it was on, it feels really good.
Great drop-in rail
by Christopher Nuzzo
This is the best option for a drop in rail IMHO. Installed in about 10 minutes. Rock solid, slim profile and free floated too. The space for the front sight tower might get in the way if you're trying to use a c clamp grip depending on the length of your arm. Worth the money.
Nice mid-length rail w/ FSB cut out

Solid mid-length rail with FSB cut out. Easy to install and super fast shipment from Primary Arms!
