The following is intended to show some of the details of the GRRW Poor Boy rifle to aid in building a copy. The pattern is from an original GRRW rifle that was built by Neill Fields in July of 1980. Of the half dozen or so Poor Boy rifles by GRRW that I’ve seen, all but one pretty much follow this pattern. The one that doesn’t is a very early version that was possibly built before they finalized the pattern.
This rifle has a straight octagon barrel that is ⅞” across the flats, 42″ long, and in .45 caliber, which is the standard catalog offering. Some other Poor Boy rifles I know of have shorter barrel lengths and larger diameter barrels accommodating up to .54 caliber. As with nearly all their models, GRRW offered options that allowed the customer to customize the rifle.
The rifle is shown in this picture. (click on any picture to enlarge)
This picture shows the location of sights and barrel loops on the barrel. The dimensions shown in the photo are in inches.
The front sight is a simple iron blade in an iron base.
The rear sight is very similar to Track of the Wolf part # RS-PA-13-L.
The under lugs or barrel loops are type that GRRW used on most of their rifles and described here.
The tang on the fixed breech is 3¼” long. It narrows slightly towards the middle, then flares to the end.
