It has been more than six years now since Ruger
entered the already-crowded AR-15 market with their SR-556
gas piston rifle. Since then, there
have been other variations to follow, as well as their successful
and affordable AR-556 gas impingement rifle. Now, Ruger has
made things really interesting with this latest version of the
SR-556; the SR-556 Takedown. What makes this rifle special is
that the barrel assembly can be removed quickly, easily, and
without tools for compact storage or transport, and can also
switch from 5.56x45mm NATO to 300 AAC Blackout with an accessory
barrel purchased separately.
Ruger engineers really earned their pay on
this design, as the process for removing the barrel from the
upper receiver could not be any simpler, yet when attached, the
barrel assembly is locked securely in place. To remove the
barrel, pull the slider towards the breech, rotate the barrel,
and slide forward. To reinstall the barrel, simply slide it into
place and rotate. Quick and simple. The adjustable front sight
removes with the barrel, and the 300 Blackout accessory barrel
also has a front sight installed. There is no need for
headspacing the barrel, is it is already set from the factory.
barrel is chambered to run both 5.56x45mm
NATO and 223 Remington ammunition. The hammer-forged,
chrome-lined barrel measures 16.1 inches in length, and is
threaded 1/2x28 TPI to accept standard muzzle brakes, flash
suppressors, and sound suppressors. The barrel is fitted with a
shortened version of Ruger's standard birdcage flash suppressor.
Like the others in the SR-556 family, the SR-556 Takedown has a
chrome-plated two-stage piston system, along with an adjustable
gas regulator, to assure function with any quality of

Ruger is not putting a standard milspec AR
trigger in these rifles, but instead, it comes equipped with Ruger's
452 Elite two-stage trigger, which results in a much better
trigger pull than on most AR-style rifles. Thank you. The
trigger on this rifle is just about perfect for a multi-purpose

Accuracy was just what I expected from this
rifle; excellent. The SR-556 exhibited very good accuracy with
both the 5.56x45 barrel as well as the accessory 300 Blackout
barrel. My concern, and the bulk of the accuracy work with this
rifle, was to determine if the barrel could be removed and
reinstalled without degrading the accuracy or changing the
point-of-impact. The lockup seems very solid, but to assure
myself that the rifle could indeed be disassembled and
reassembled without losing
accuracy, I switched repeatedly between the 5.56 and the 300
barrels. I mounted my Leupold
Mark 4 atop the receiver,
and starting with the 5.56 barrel, fired upon a target at 100
yards distance. Then, without touching the scope settings, I
switched barrels and fired the 300 Blackout barrel on the same
large target. After five shots, I switched back to the 5.56
barrel, and fired again. I repeated this exercise several times,
with the result being a target with two tight groups; one from
the 5.56 and the other from the 300.
The Ruger SR-556 Takedown is an excellent
rifle, and really different from anything else on the market.
The value of getting the rifle disassembled into such a small
package for transport or storage will vary with the user.
However, even if compact storage is not of primary importance,
the ability to switch calibers without changing the entire upper
is a great idea. The barrel locks in securely, and loses nothing
in accuracy. The Ruger SR-556 takedown comes with rail covers,
three thirty-round P-MAG magazines, instructions, lock, and
padded case. Like all Ruger firearms, the SR-556 Takedown is
built in the USA.
