| Will KAC ever make a full length RAS II? If they do, I've never seen one. |
| URX project is a FF system in the works by KAC. Has benefits like RAS and RAS II. Like RASII it free floats but will allow the upper reciever rails to continue uninterupted down the entire length of the forend while not changing the height of the upper reciever rails. There are many many other attributes as well that I am sure KevinB or ColdBlue could better explain. There are other posts on the board devoted to the URX as well. It sounds like the poop from what I hear! |
| The RAS II makes it difficult to mount a conventional scope. If you are using an aimpoint or ACOG, then it works fine, but try to mount a full size scope to the RAS II and you run into problems. I don't think the hump from the RAS II would be a good idea on a rifle. Personally, I think the FF RAS is the best for that. |

Quoted: The RAS II makes it difficult to mount a conventional scope...FF RAS is the best for that. I think "difficult" is very "scope" dependent. Some scopes of short overall length will have a front scope ring mounting issue with the RAS II "bridge" (at least until someone comes up with a ring of appropriate heigth). But on some large variable power scopes, where the power ring literally moves the scope closer to your eye, I find mounting the front ring on the RAS II a very good option to having the scope mounted too far back, i.e., hanging back over the charging handle. Especially if you follow the old gunsmith's rule of spreading the scope rings as far apart as possible on the scope body for its best stability. Remember, most all these commercial scopes are designed for bolt action rifles and have about a 3 1/2" eye relief, and then just so much scope body area appropriate for scope ring attachment. Of course for a 20" barrel capable of sub-moa, the FF RAS would be the best choice, all other things being equal. But with the RAS II's lower rail and its integral barrel nut lip clamp and 2 indexing dowel pins that help secure the upper RAS II as well, once assembled, RAS II is extremely stable for a free-floating rail forend system that installs in less than 30 seconds. ColdBlue got to do yard work now... |

Sorry, forgot to add that a rifle length RAS II is no longer on the drawing boards at this time. All our efforts are on the URX series rifles and carbines on contract "this year" to US Military & Government. They probably will not be available commercially (either on weapons or on uppers--no final decision on this issue as of yet) until 2004. ColdBlue really go to go now... |

BIG SCOPES ON 16" BARREL [OR LESS] CARBINES ARE TO ME A MISTAKE, OTHER THAN FOR DETERMINING THE WEAPON'S ACCURACY POTENTIAL. THE RAS II WAS DESIGNED SPECIFICALLY TO WORK WITH THE TRIJICON TA01NSN, A NICE COMPACT 4X SCOPE THE GOV'T SELECTED AS A PART OF THE ORIGINAL SOPMOD PROGRAM. THE TA31 IS OF COURSE THE SAME DIMENSIONALLY AND ANOTHER GOOD CHOICE. A 3.5-15X50 NIGHTFORCE NXS IS ANOTHER GREAT SCOPE. SO IS THE 3.5-10X40 LEUPOLD LRM3. AND I HAVE MOUNTED SUCH SCOPES ON 10.5"-16" UPPERS! JUST TO SEE HOW WELL THEY WERE CAPABLE OF SHOOTING, HOWEVER! NEITHER WOULD BE A GOOD CHOICE FOR A 10.5"-16" .223 CARBINE IN A "CARBINE" ROLE.
