You have a better chance with the RAS, but I would keep my ranges short - 200yds or less.

Some say yes, some say no, some say yes but with a disclaimer... For a few bucks more, you can get the RAS II or a SIR system and not worry about it.

I had a Trijicon reflex mounted on my [b]RAS[/b] for several years. But I considered it a sub-200yd gun. I [b]prefer[/b] reciever mounting. Why give yourself any doubt?

Go with a cantilever mount, instead.

I have a RIS, and it feels pretty solid on my upper.
Then I added a vertical foregrip, and that "solidness" is gone. Use a cantilever mount shown above, or get a free float RAS if you want to mount optics forward of the receiver and have a vertical foregrip. -Zmeja |

Option #3....ARMS#38 MOD + RIS. Solid as a rock and you can mount your optics as far forward as you'd like.

...........or instead of the RIS go with a RAS! But like stated above a few bucks more gets you the RASII or a bit more and there the SIR. Mount anywhere ya want on those! With some pro's and con's you can read EVERYWHERE on this site[:)]

No , the Aimpoint ,or the EOtech, does not hold the zero if mounted forward on a RIS , above all if you have a vertical foregrip to hold the AR with your not-strong hand .
Mounting it on a RIS can be done , and it can work , but only for very close shooting , the POI'll not change really very much . Best choice 'd be the FF RAS , this is rock solid indeed , even if I do not mount any optic on any kind of forend . The RIS, RAS , RASII , FF RAS & SIR , are made to attach aimers,illuminators,flashlights & vertical foregrips , no optical sights. PP out |

Postban, right? Why the scope for 9mm? ;) Its a 45. The scope is a 1.5 x 4.5 EER. Just as fast as a red dot but it gives me a little magnification for those 100yd shots...plus no batteries. |

Quoted: Quoted: Just as fast as a red dot .... Slacker, no flame intended but pls let me doubt it . PP out Have you ever used a 1.5x forward mounted (scout) scope? Why would a red dot be any faster than regular cross hairs on a low power varaiable? Paralux free you say? Perhaps, but only by a very small fraction. I prefer the EER (extended eye relief) scope because it gives me the option of magnafication for those long shots and lets me mount it forward of the receiver for a large field of view. At 1.5x the field of view is enormous. There was a thread in the Optics forum about five moonths ago on using a scout scope on an AR. Popular opinion was that it worked great...and I agree. Sorry if none of this makes sense, I've been up since 4am and its past my bedtime. G'night all. |

The Brit's (SAS) had the same issue with "stability", se we (KAC) designed a new lower that fits both the Carbine RIS and an M4 RAS. The new lower (P/N: 20033) has a rear clamp like the upper RAS and two dowel pins that the clamp (tighten with a 1/8" allen screw) pushes into the barrel nut cut-outs at 8 and 4 o'clock. This makes the lower more secure, especialy if lots of pressure is applied to the Forward Pistol Grip, as well as help further stablize the upper.
However, if your barrel will accept a RAS, i.e., mil-spec carbine/A2 Rifle barrel profile, always go with a RAS. The RAS is more stable for forend mounted optics. The RIS is fine for what it was originally required to do. For example, mount bore sighted IR Lasers. Since these are used in conjuction with night vision goggles worn on the face and the weapon usualy fired from the hip or "over the sights", you can hit man-size targets all night long, but you can't shoot sub-moa groups using this method. So when guys scout mount optics out there and fire from a bench, they see the degradation in group size when compared to upper receiver mounted optics. ColdBlue sends... |

Thanks Cold Blue. That new RIS seems like it might work for me. I think I will look at other Aimpoint mounting options.

I see no point installing a RAS if you can't mount a sight forward. You can add anything else to much cheaper Samco handguards.

Several units forward mount optics on the RIS and RAS...
I was once an unbeliver but I have seen some hard used guns with RAS's and forward mounted EOtechs that still hold their own. PP is correct as usual in pointing out the FF RAS is the most stable platform, well until the URX and URXII release. |

If one picture is worth a thousand words, check out page 7 of US News & World Report (June 23, 2003 issue).
Now its more likely that this Soldier's M4 has one of our M4 RAS's on it (one of the 125,000+ delivered to the Army so far), but it looks to me that his Aimpont is mounted on the RAS's top rail. ColdBlue sends... |

What? No sirs Sergeant?
No sirs, Sir. I like the cable ties, now that would really tighten things up and might also keep from loosing an Aimpoint in a parachute jump. ColdBlue appreciates you posting the pics, I had not seen any of these. Thanks... |

I definetely think you can mount optics on RAS II and SIR without ANY problems since both combine additional strength from the receiver.
