| Whats the purpose of the raised portion on the RAS II. What are people mounting on that little strip that comes back over the top of the receiver? |
| I believe it's an anchor point to the upper...the RASII is a free float hand guard, but you do not have to remove the stock hand guard cap, delta ring and FSB; hence the "hump" anchor bridge. I have not handled one since SHOT 2000...so I might be wrong. It's one of the few KAC handguard systems that they ALWAYS have in stock-seems like they are not nearly as popular as the RAS, RIS or the conventional free-float tubes that Knight's offers. I'm impartial to the FF RAS "MRE" model for carbines, myself. |

A good combination comes to mind: an Aimpoint with a low profile American Defense mount KAC low profile mount.

I'm impartial to the FF RAS "MRE" model for carbines, myself. You have it correct. The "bridge"of our (KAC) RAS II with its cross-bolt/clamp, and its clamp that engages under the lip of the barrel nut, are what holds the rail truw to the host weapon upper receiver. Thus providing a free-floating barrel at an extemely low level of effort and no gun modification. And its removable lower is a version of our secure SAS type lower RIS/RAS rails. Absolutely the best of both world's IMHO. And thanks to Quarterbore above (see the link), always nice to see some of my work & photos... |

Your welcome ColdBlue...I am a fan and user of KAC goodness since I owned my dearly departed SR-25 from "KMC"...don't ask-it was not voluntary...grrr.
Please make a SR-"26" for those of us that live in restricted by "name/model" states. Love my RAS setups...rock solid. Nice write up in SAR too BTW. |

I really like my RAS II, too bad you don't make a mid-length version....
