I finally got a chance to try out the SL8 I bought a few weeks ago at the Tampa Gunshow ($1400 out the door. Seller was looking to fund a new host MP5). The seller said he had only put 40 rounds down the tube, and I only got the rifle and the magazine, and there is some marring on the barrel (the stock looks exceptional), but I was satisfied with the price.
I must say this could quickly become my favorite rifle. The action is smooth. and the trigger is crisp and feels very clean. The previous owner had stated it was a very accurate rifle. And, after shooting it I believe him.
10 rounds 63 gr SS109 Radway Green at 50 yards:
This was shot supported from a bench on an indoor range supported by a leather shooters bag with factory "iron" sights. NOTE: I called one flyer (the isolated lower right round, I believe, but I DO COUNT 10 rounds in the target.)
As a comparison I also took my trusty SIG 556 to shoot so that I could confirm my zero with my Trijicon Reflex II sight with 12.9 MOA triangle recticle.
This shoots the Radway green very well also. As a comparison I shot the following
20 rounds 55 gr G223B-1 Georgia Arms (rated at 3150 fps) at 50 yards:
This actually is a torso sized target that I folded into thirds for ease of transport. I can make out at least 18 rounds in the target (there could be all 20 but I cannot confirm this). These were fired supported like the SL8 but at a more rapid pace.
I love my SIG 556, and it is still pretty much my goto gun for medium range in 5.56 x 45 mm / .223 Rem., but if I had to be assured of putting a round in a target accurately I will now go with the SL8.
I had no problems with the SL8 and one failure to extract on the SIG 556 which was cleared with minimal trouble.
Also of note is the ease of cleaning for the SL8. It is much easier to clean than the SIG 556 (in fact it may be the easiest rifle to clean that I own with the exception of my PS90). A simple wipe down of the parts with an old oiled rag and a boresnake down the barrel was all it took. I know from past experiance that the SIG 556 will not be nearly as easy to clean.
All in all I am very impressed with the SL8. It is a comfortable rifle to fire, seems well balanced, properly weighted, and shoots accurately and well.
