Product Description


The takedown barrel is removed from the upper receiver by simply moving the slider bar towards the breech, rotating the barrel and pulling it free - no tools required. Installation is simpler yet - just slide the barrel into the upper and twist until it locks. The takedown mechanism provides a repeatable point of impact. Ruger® patented chrome-plated, two-stage piston with multi-stage regulator provides a cleaner, cooler running, reliable firearm with superior operating endurance. The two-stage piston provides a smooth power delivery stroke to the bolt carrier. The Ruger® Elite 452™ AR trigger is a two-stage trigger that offers a smooth, crisp, 4.5 lb. trigger pull. The Ruger Elite 452™ features a full-strength hammer spring for consistent primer ignition and a lightweight hammer that enables a 30% faster lock time over standard MSR triggers. With front and rear folding iron sights, the SR-556® Takedown is ready to go to the range right out the box. The front sight is both elevation & windage adjustable, meaning that when you swap barrels, the zero stays with the barrel. The lower receiver is fitted with the Magpul® MOE grip and MOE SL collapsible buttstock on the mil-spec buffer tube. With a length of pull ranging between 11.1"-14.4" the fit can be perfect for most any shooter. Precision-rifled, chrome-lined, cold hammer-forged Mil-Spec 41V45 chrome-moly-vanadium steel barrel ensures accuracy and longevity. A Ruger® flash suppressor is provided and the ½"-28 threaded barrel allows for standard muzzle accessories to be installed. Supplied with three Magpul PMAG® 30-round magazines (a lightweight 556 NATO magazine). Also includes a rugged, ballistic nylon case; three rail covers and lock.

Firearms Policy

How to Buy a Firearm or Ammunition

Federal firearms laws prevent the sale of a weapon from Red Dot Arms, LLC. directly to an individual in another state (we are located in Illinois). We must ship your firearm directly to an FFL Dealer near you. The steps to follow are:

  1. Order your firearm online using our secure shopping cart. If you know the FFL dealer you are going to use at time of order placement (not a requirement) enter his name and address into the 'Ship To' field.
  2. Find an FFL dealer near you that will accept the transfer of the firearm for you. Most sporting goods stores and pawn shops will provide this service for a small fee. Also, gun clubs, shooting ranges, etc. may provide this service to you. If you don't know which FFL dealer to use in your area, put a comment in your order and we will help you locate one near you. We have access to a large list of dealers in the USA that will gladly handle a transfer for you. Most dealers charge around $25 for a transfer. You must confirm the transfer with your local FFL dealer in advance.
  3. Next, have the dealer send us a copy of his signed license if we don't already have it on file. To check whether a license is on file, contact us. Please Note: It is now legal for us to accept a faxed or e-mailed copy of your dealers license! 
  4. Make sure the dealer knows the firearm is coming from Red Dot Arms. If you used a dealer that we already have on file, call him to let him know that a gun for you is on the way.
  5. We will send you an email when the firearm ships, which will include a tracking number.
