Outstanding Carbine
I have now had my SR-15 purchased through Brownell's for a year now.The carbine is excellent and the improvements Knight's Armament Co. has made to the AR-15/M4 platform are well worth the money spent.This is easily the softest, smoothest shooting 5.56mm carbine I own or have tied short of gamer guns with giant obnoxious muzzle brakes/compensators.Keep in mind this is a hard use, duty ready carbine made for reliability and a harsh firing schedule.Although not marketed as a match grade carbin...Read more

All I can say is WOW...
I purchased this rifle a little over a month ago (thanks again to Brownells for the Veterans discount) and put over 300 rounds of PMC .223 Remington Bronze 55 grain FMJ-BT through her over the 4th of July weekend.She shot flawless and was able to quickly get her zeroed in at less than 1" shot groups at 75 yards with a 1x green dot optical plus the included flip up iron sights.It is true that the recoil is less than that of a .22 caliber rifle and it makes her so sweet to shoot!!!I was amazed ...Read more

Yes, it does...

Two-Stage Match Trigger

All of the weapons available from Knight’s Armament come equipped with a 4.5lb, 2-Stage Match Trigger. This type of trigger mechanism uses a system where, during the rearward squeeze of a trigger, it cycles through two stages of resistance.

 

The first stage is a ‘no-poundage’ stage where hardly any resistance is felt during the rear-ward squeeze. There is a center point at which point resistance is felt and the second stage of the trigger begins. At this point, 4.5 pounds of force is required to squeeze the trigger through the second stage and cause the weapon to cycle. 

Our 2-stage trigger is meant to inform a shooter of exactly where their weapon is going to fire. This bolsters a firer’s confidence and can also assist in reducing trigger jerk, thereby increasing accuracy. The 4.5lb 2-Stage Trigger from Knight’s Armament is a highly calibrated and smooth component that is sure to be a welcome addition to any setup.
