Why our M14/M1A Scope Mounts?

Bassett Machine

Out of his passion for shooting accurately, Bill Bassett, designed and built his own scope mount, our standard M14/M1A Scope Mounts, to cure the shortcomings he found in the ones he bought with rifles. And guess what? It worked. And it’s still working today.


What did independent testers find?

  • the bolt he designed held the mount securely;
  • the material he chose held up to the beating of the recoil; and
  • the design gave sufficient clearance for empty case ejection.

FAQs

M14/M1A Scope Mounts

  • Known Barrel/Action Issue

    A few customers have reported that their shots when using our M14/M1A Scope Mounts were high/right or low/left.  After some investigating, we discovered that some rifles had a barrel that was not parallel to the action.  The Vietnam-era Telescope/Auto-Ranging ART II Operation Manual even documents this issue and how to work around it with the ART II Scope. Here is a document that we drew up to help you determine whether your barrel and action are parallel, which will help when using our M14/M1A Scope Mounts

  • Scope Directly Over the Barrel

    When using the Standard High or Standard Low M14/M1A Scope Mounts, you may find the scope is not directly over the barrel. While it isn't essential that the M14/M1A Scope Mounts be over the barrel, (and it's only off a fraction), if you don't want to allow for it, we've found that the Standard Low M14/M1A Scope Mounts with high rings will place the scope directly over the barrel

  • Using Loctite... or not

    Bassett does not recommend using Loctite on the mounting bolt. It is not necessary and wrecks the ability to remove the mount/scope unit when not needed. Testing by the AMU at Fort Hood, Texas, in 1980, determined 22 inch-pounds to be sufficient to hold the mount with no shifting and yet not distort the rifle action or compromise accuracy.  If you want to put Loctite on something, Bassett says using it on the ring screws wouldn't hurt...provided you didn't want the ability to mount different scopes on the mount.

  • Iron sights

    Using the Standard High M14/M1A Scope Mounts, a 65mm outside diameter objective bell will clear the hand-guard by 1.5mm. This measurement was taken at 6.5 to 7 inches forward of the mounting bolt center with the recommended old-style Weaver rings. This allows for using the iron sights with our M14/M1A Scope Mounts.

  • Note about Weaver Rings

    Bassett recommended Weaver Rings back in the beginning: Weaver medium height styles # 49041 or 49120 for 1” diameter or 30 mm scope tubes, respectively; and styles # 49045 or 49152 extended for ¾” eye relief with 1” or 30mm diameters, respectively.


    Since his recommendation, weaver has changed their product’s (“Style”)1; We have not tested weaver rings with our M14/M1A Scope Mounts since then and Bassett would probably still say go with the old style if can find them at a gun show. He used to say “They might not win a beauty contest but they were functional”


    We don’t know if they’ve changed materials or quality so use it with our M14/M1A Scope Mounts at your own discretion.

  • Returning to Zero

    Camp Perry Hi-power Masters and law enforcement personnel found that if reinstalled to the original mounting torque, our M14/M1A Scope Mounts will return to the battery within a half-minute of the angle at 100 yards. Consistency of weight and method installing is what produces the best accuracy with our M14/M1A Scope Mounts.
