The Troy Delta BattleRail is a revolutionary freefloat, modular, drop-in rail system for AR-15s. This rail requires no gunsmithing to install, and freefloats the barrel for improved accuracy. It features two integral QD swivel mounts, and offers the benefit of an extended forearm while retaining the factory fixed front sight post. The Delta BattleRail utilizes a rock solid rotary clamping system that does not require the removal of the delta ring, barrel nut, or fixed front sight. Much like the Alpha Rail, the Delta BattleRail features rounded cooling holes that double as mounting points for additional rail sections for adding accessories. These cooling holes will also accept Troy Squid Grips. The Delta BattleRail is manufactured from 6061-T6 hardened aircraft grade aluminum and MIL-SPEC Type III hard coat anodized in matte black.

NOTE: Not compatible with the Ruger AR 556 due to a built in QD at the bottom of the A2 front sight.

Removal of front sling swivel required.

  • Installs in minutes
  • Allows users to add smaller rail segments without the added weight of a full-length quad system
  • Extended tube past the fixed front sight
  • Includes two built-in Q.D. swivel mounts
  • Machined from hardened aircraft aluminum with stainless steel components
  • Finished in MIL-SPEC hardcoat anodizing

troy battle rail


All in all this is a great rail the reason I used this for my build is because I like the standard FSB for it's durability and looks the standard FSB with a free float rail looks pretty cool but installation is tricky I have installed many troy alpha rails but it fit so tight on my gun I couldn't get the last screw to line up shipping and service from primary arms is second to none and troy customer service is fantastic since I couldn't get the last screw to line up now matter what I did I sent my upper with the rail to TROY industries and they were excellent I sent my upper out on Thursday had it back Tuesday no joke very fast. Knowing what I know now my next AR15 build will have a low pro gas block and troy alpha rail but all in all its a very good rail sturdy and looks great I'm going to take a carbine class with it to see how it holds up

Troy Delta Battle Rail


Great quality, very good price, fast shipping, what else could you ask for.Typical awesome customer service by Primary Arms

This rail is incredible!


I can't believe the lack of weight. Incredibly light. Don't be fooled. You will most likely need tools and some time to get this rail added. What I found was, that you have to remove your flash hider, remove the front sight assembly, remove the fitting for your stock or non free floating front hand guard (this is the piece that gets in the way. Then, add new Delta rail easily. This is a great free floating system. Incredibly strong feel, look. incredibly light.

Troy Delta Battle Rail is an Excellent Product!


I have ordered two of these in the past couple of weeks. The first one was for my step fathers build as he was wanting a free float set up, and did not want the additional cost of removing his front sight post and changing gas blocks. The installation was simple and easy, and the locking tabs on each side do an impressive job of locking it in place. Fit and finish is excellent. I was so pleased with how my step fathers build turned out I bought one for myself. Primary Arms also had hands down the best price on these I could find anywhere!

Troy Delta Battle rail-carbine length


I have researched all the handguards that bypass the standard a2 front sight with extra length and decided on the Troy Delta Battle rail. The Delta Battle rail is light weight and has detailed craftsmanship and installs very easy - If you use a good handguard removal tool and can move the delta band back as for as possible, the last piece to install will slip into place with ease. Lastly the overall look of the Battle rail is just the look I wanted. Of course the shipping was outstanding as always - I try to buy all my ar15 goods from PA.

service continued


I know that in order to keep the prices so competitive you must control and keep overhead as low as possible. I am sure that is why PA really isn't set up for retail business and all transactions must be done via computer.I walked away feeling like i would have been better off paying for the freight. I really didnt feel like i was appreciated and maybe just a little bit of an annoyance by being a walk-in customer.By the way there were 2 other store employees i assume (an older man and a woman) that were very nice and seemed to care that i was there but not the young guy behind the counter.i run a family service company too so i know the value of constructive criticism. PA is awsome and i plan on continuing to shop there but i just wanted to give feeback about my experience.RobModerators Note: We have a small show room that is really meant to be a will call. We are happy to help out customers if we are not busy but the ONLY way to order is through the site. Thank you!

Dont Give Up!


I love this rail...I've wanted one since i first saw them. Finally broke down and got one. Installation was extremely problematic though which is why I'm only giving it 4 stars. I had no real problem getting the rail on, it does take some maneuvering and a hand guard tool or a second person would make it easier but my biggest problem was the clamp screw holes would not line up with the holes in the rail. I tried everything i could think of for a week before i bought a file and made the holes in the rail bigger...fits great now! Nice and solid. Might not be something others would want to do though, filing on a $200 piece of aluminum. However, I'd still buy it again.

Great option for carbine


If you are looking for a reduced diameter extended length hand guard, this is it. The rail attachments are right where I needed them, it's well built and easy to install

Quality rail


Install was moderate but easily done by myself in a few minuites. Rail looks good and fits great. Real sturdy and super lite product. After searching countless websites for best price primary arms had it! Customer service in my opinion is 2nd to none!
