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

It works.


Simple and easy install, mounts solidly, everything you expect. Gives you that extra length us longer armed fellas might need.

great drop in


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.

No machines


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!!!

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.



This rail exceeded my expectations. Easy to instal, locks up tight and feels great. Troy has my vote.

Best Rail System


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!
