Recognizing a void in the market for a modified M1 Garand operating rod catch, machinist Clint Whitehair has developed the new M1 Thumbsaver. It offers the same functionality as the previously available Holbrook device (June/July 2020, p. 40), but is machined from hardened 4150 steel and features a Parkerized finish and Teflon-infused lubricant. The device prevents “M1 thumb” and allows easy loading of rounds individually into a standard en bloc clip. When a clip is inserted into the rifle, it locks into place and holds the bolt open. The first round is loaded by pulling back and releasing the charging handle. When the last round has been fired, the rifle locks open on the empty clip, which can be ejected by depressing the clip latch. The device is easy to install and does not require permanent modifications to the rifle. Price: $75. Contact: Mountain Aerospace Machining; (406) 552-7516; m1thumbsavers.square.site.
