Description and Specifications

The Troy carbine length Delta BattleRail is a revolutionary free-float, modular, drop in rail system for carbine length AR-15s. This rail requires no modification to the host firearm, requires no gunsmithing to install, and free floats the barrel for improved accuracy. It features two integral QD swivel mounts, and offers the benefits of an extended forearm while allowing the user to maintain the factory fixed front sight post. Like the rest of Troy's new drop-in free-float rails, the Delta BattleRail utilizes a brand-new and 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 Troy Industries Carbine Length Delta BattleRail is manufactured from 6061 T6 hardened aircraft grade aluminum and MIL-SPEC Type III hard coat anodized in matte black.

Alignment issues with barrel nut. Top half of rail does not line up with center bore of rifle. Similar issue with lower half...grooves on barrel nut portion of rail do not match grooves on barrel nut itself. M&P 15 Sport

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. Rob Moderators 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!

Great rail!

Excellent quality that you expect from Troy. Great look and fit, locks up tight, installs easy, not much more that you can ask for. It won't disappoint.

Super easy and solid install on my Bushmaster. The lower portion slides around the end of the barrel in front of the FSP and underneath the FSP down to the Delta ring. The upper portion drops in from the delta ring to just before the FSP. A set of clamps installs around the barrel nut's "teeth" and 4 bolts secure the rail. Be carefull not to strip threads during this process. Troy has awesome customer service as well; You'll get the Info/replacement parts you need quick! Troy industries is first class!!!

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.

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

Just received it yesterday and mounted it last night. It was a little tricky for me to figure out the way it mounted, but once I did it went on like a charm and seems nice and solid. I never did figure out exactly how it was attaching itself, but it works. I like the feel of it too. I thought that bottom rail might feel odd to grip, but it doesn't. Time will tell on the product as a whole, but so far "GOOD JOB"!!!

Incredibly fast delivery. It went out the same day I ordered it. The rail itself is of excellent quality. It installed easily on my Bushmaster fluted hbar w/out issue.

Troy Delta Battle Rail is an Excellent Product!
Ray from N/A wrote on August 10, 2015:

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!

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

Best Rail System
Leland Minder from AZ wrote on August 10, 2015:

Troy Industries Battle Rail Delta is by far the best and nicest rail and hand guard system you can get for a rifle that still has the A2 front post. Unlike other company's rail systems you have the option of choosing where you want your rails to be. It is very light weight and stays cool. By far the best thing I have purchased for my M4, it has improved our relationship lol. Other manufactures charge a ridiculous price as well. Troy Battle Rail Delta is affordable and very effective. Primary Arms had a good price on it and shipped it fast. Excellent service!

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

This rail is incredible!
DeGregory from MO wrote on August 10, 2015:

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.

great drop in
ryan from TX wrote on August 10, 2015:

Solid. Good looking fit. Take your time and it will clear the plate at the front sight so you don't have to remove anything but the hand guards. Extends grip area and is very comfortable.

Great Rail

The quality of this rail is outstanding. It took a little coercion to get everything lined up to install, but once on it is rock solid.

Quality rail
Jonah "Trigga" Boudreaux from N/A wrote on August 10, 2015:

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!
