Here is another review by another person from defencereview.com.

[email protected]The SAR-21 is a roughly 2 1/2 year old, "state-of-the-art" bullpup 5.56mm assault rifle that is currently going head to head with the Israeli TAR-21(Tavor) bullpup rifle, and all other modern 5.56 assault rifles on the world market. Judging by my experience with this rifle at the range, the SAR-21 is going to give its competitors a...
serious run for their money (more on that later).
The rifleÂ’s combined stock and receiver is comprised of an advanced polymer, and thus is fairly light. Since its bullpup configuration leaves the shooterÂ’s face very close to the chamber, STKinetics has thoughtfully designed a protective ceramic plate into the stock, along with an overpressure bleed hole in the chamber, to protect the shooterÂ’s face in case of catastrophic failure. While I liked the ergonomics of the ambidextrous cocking/charging handle on top of the receiver and under the optical sight, I don't particularly like reciprocating cocking/charging handles on an infantry rifle, particularly one located on top of the receiver, a la the SAR-21 and HK G36 series. A reciprocating cocking/charging handle makes it impossible to have a true 1913 picatinny rail. Anyway, like the HK G36, this handle swivels, so righties and lefties can operate it with equal speed and efficiency.
The SAR-21 also incorporates a gas regulator at the front of the rifle that can be adjusted for different loads, similar to what can be found on the FN FNC, although the design is different. Magazines are made out of a clear polymer, similar to the magazines for the HK G36 and Sig 550 series rifles. So far, the SAR-21 only comes in standard configuration, as far as we know. Hopefully, carbine and subcarbine variants will be developed in the not-too-distant future. As far as DefRev is aware, Class III Supply, out of Hermitage, PA, is still the exclusive importer/U.S. distributor of the SAR-21 bullpup assault rifle being manufactured/marketed by VT Kinetics and ST Kinetics Land Systems out of Singapore. Vincent DeNiro is the owner of Class III Supply.
I got to shoot the SAR-21 rather extensively awhile back during "Range Day" at TREXPO East 2001, right after the gun was first introduced to the American market at the two-day exhibition. The demo gun was provided by Class III Supply, and they were very generous with their ammunition, allowing people to pretty much shoot as many rounds as they wanted. I should say off the bat that I usually donÂ’t like bullpups, but I really liked this one. In fact, this gun turned out to be my second favorite weapon at the shoot (My first favorite was the FN P90). I had an absolute blast running this gun.
The optical sighting system on the SAR-21 worked really well, being very fast to engage, and recoil was very manageable. With proper stance(I, myself, use an SAS stance with both elbows tucked in close to my body), the gun stayed on target during full bursts, and the hit percentage was extremely high. I was able to keep all my rounds within about 6 to 10 inches at 25 yards on full auto, depending on the length of the string. The balance of this weapon is superb, being right above the shooting hand, and the weight is light, considering this is a full sized 5.56 rifle. Reliability was perfect while I was firing it, and I did not see even one malfunction of the SAR-21 the entire time I was there. One of the contributing factors for this was the excellent polymer magazine. I especially appreciated the see-through feature, which allowed me to monitor my ammo supply.
The only things I did not like about this rifle were the location of the selector switch, and the type of switch it is. Located at the back of the stock--not a good place, by the way--it is of the push-button variety, and was awkward to operate. I would much prefer an ambidextrous M16-style sweep selector switch that can be engaged by either the thumb or index finger of the shooting hand. That solution would be far superior with regard to speed and ergonomics under combat conditions. If ST Kinetics/VT Kinetics makes this one change, the SAR-21 will be very hard to beat in the world market. One other suggestion I would make is that they come out with both carbine and subcarbine variants for use by special operators.
The SAR-21 is currently only available to law enforcement organizations and military units.
