| I just bought a flat top, HBAR, varmint type rifle with rails all the way down the float tube/handguard and will probably buy a leupold M1 3.5-10x40mm IR to go with it. I am new to scoping the AR. I have searched the posts on this topic and am a little confused as to why I would need a separate mount or swan rail. My M14 needed the ARMS mount because it has no integrated rails on the receiver. Also, what size ARMS rings would you suggest for my new setup. Thanks! |

Two options if you choose the Leupold M1 3.5-10X40: 1. Not necessarily the best, but will work is any set of quality 30mm rings. Medium Height, assuming you do not plan on BUIS, and High rings if you want to have a BUIS. The M1 has such long eye relief, the rear objective will need to be positioned directly over the charging handle or actually a little in front. If not your cheek position will be too far aft on the stock. The only problem that may come of this mounting style is the forward ring will have to be mounted to the free float rail, not on the receiver (not enough room). Some do not see this as a problem, but the receiver and forend rail have to be on the EXACT same plan. If not the scope be stressed in the unparallel rings. 2. A cantilever style mount. The ARMS #35 Track Mount and #35 Medium Rings (medium rings have an insert, so you could just use the rings and make it a low mount) would be a excellent choice. Two of my AR are configured this way. It allows you to mount the scope about 1.25" forward of the end on the receiver. The Armalite 1-piece base is another option, but the height is fixed. The rifle in the front has the Leupold M1 in the ARMS #35 mount and medium rings. [img]mysite.verizon.net/vze1ywph/jpgs/buddies3.jpg[/img] |

As mentioned, eye relief is the issue. In order to properly position the scope, ye nedd to either: 1) get and extended mouns such as the ARMS #35, #38 swan sleeve or the Armalite.

I have done this with my KAC Match with Free Float RAS forend. Depending on whether you believe your forend is rigid enough, this might be an option. Leupold Mark 4 extra high rings: [img]http://photos.ar15.com/ImageGallery/Attachments/DownloadAttach.asp?iImageUnq=15212[/img] Head over to the Optics section, this has been discussed may times with many opinions [;)]. |
| Thank you for the good info! I have decided on the ARMS #38 mount with swan sleave and the medium ARMS #22 rings. I believe the swan sleave over the float tube rails will give extra strength and the ARMS mediums will give me sufficient eye relief but keep the scope closer to the barrel. Does that sound right? Its my understanding the ARMS rings are "see through". Will I be able to use the BUIS with the scope attached and the medium rings or does that require the high ones? Your experience is greatly appreciated! |

That will work if you use the #38 EX or S-EX for more length. Its my understanding the ARMS rings are "see through". Will I be able to use the BUIS with the scope attached and the medium rings or does that require the high ones? Your experience is greatly appreciated! Think about it - the scope occupies the line of sight of the irons, unless it is mounted about 5" above the bore line. So no, you can't access or use the BUIS with the scope attached. But since the ARMS rings are QD with the throw levers, you can just pop it off and use the irons. Return to zero is good when removing / attaching the #22's. |

Here's Leupold Mark 4's and NO rail. Very pricey....... [url="http://www.hunt101.com/?p=79525&c=548&z=1"][img]http://www.hunt101.com/img/079525.jpg[/img][/url] Here's some Leupold See-Through's that will work just fine with no riser rail. They are 1.4 inches high from the apex of the Picatinney rail to the center of the scope. $17.00 a pair at Walmart of all places......

Like $12.00 a pair most anywhere......... |

FWIW, I use the high ARMS rings with the #38, and that setup works pretty good, although the mid length #38 would have allowed for slightly better eye relief. Had I known before hand how I was gonna set this rifle up, I'd have opted for the longer #38. Also, as you can tell by the pic, if you're using a scope with a bigger objective, the extra height from the high rings will come in handy. I *believe* the objective on this one is 44mm...it's a Simmons Aetec 3.8x12. [img]http://img.villagephotos.com/p/2003-7/188491/modular1.jpg[/img] |
