It sounds like a good theory to me and besides using my Unertl on a USMC clone gun I removed the spring as insurance against harming the scope. After firing the shooter has to pull the scope back into battery.
With no spring when the rifle is fired the scope sits in space while the gun moves rearward under it. Their belief was that with heavy recoil (30-06) they wanted to limit the forces the scope was exposed to. The USMC removed the recoil spring on the tube.
Loosen those two small screws and rotate the drum to your zero. Look for two small straight blade screws on the numbered elevation or windage drum. Don't expect markings to be exact but you will find them close.ģ.

They specifically cited a 8x target scope made by John Unertl as being the best they found. The avalability of parts to support the 722 is c. After there was a push to standardize sniper equipment, the Marine Corps Equipment Board did an extensive study of optics under field conditions and recommended a scope of about 8x, with an objective lens of about one and half inches, a medium fine crosshair reticle, and double micrometer quarter minute click mounts. 222 Remington Model 722 rifle with a Unertl 6X scope for urban sniping.

As you can read in another article on this web site, I recently became involved in late 1800 rifles and the period correct scopes to go with them. The M1903-A4 was an accurate rifle with an effective range of about 600 yards (550m), with the main limit on long range accuracy coming from its very low power scope (2.5x). The rifle was officially adopted on as the M1903-A4 (sniper). The Infantry Board and the Ordanance Department conducted an evaluation and recommended that the Weaver 2.5x 330C hunting telescope be adopted for use on M1903 and M1903-A1 rifles. There was a high demand, that could not be filled, for telescopic (sniper) rifles.
