Question on measuring LOP?

Post by **fox-admin** » Tue Apr 21, 2009 10:10 pm

Most Fox guns show 14 1/8LOP with a hard butt plate. Do you measure from the center of the front trigger to the back outside edge of the butt plate or from the center of the front trigger to the center of the butt plate? By center of the butt plate I mean the center line between the two screws. Since the butt plate is higher in the center than the edge, it results in about 1/8" longer LOP. I don't have a gun with a butt plate that letters (the cards are missing). They both measure 14" from the front trigger to the outside edge of the butt plate. If I put a square on the table and measure to the center of the butt plate they measure 14 1/8. What is the correct method to use for Fox guns?

I don't know that there's a "correct" way, and 1/8" inch is a pretty fine point to argue, but my preference is to measure to the highest point in the center of the butt. I usually eyeball it with the gun lying on its side. If I were to use a square, I'd still make sure the short leg contacted the center of the butt. Standing the gun on its butt and measuring up from the table is probably OK most times, but you could have enough curvature that the butt only contacts the table at heel and toe, and not the center of the butt, thus exagerating the measued LOP. If "LOP" is to have any meaning at all to me, it needs to reference the point where the butt contacts the shoulder, not some some other imaginary line.

I agree with Mike.... the measurement from the curve of the front trigger to the surface that contacts your shoulder in the middle of the buttplate or pad. Just "eyeball it" while measuring if the butt is slightly convex. Silvers

There are really three LOP measurements, all from the center of the front trigger. The one that is usually given is to the center of the butt. The other two are to heel and toe. The three together give you another indication of pitch. You can get a rough measurement with a tape measure but you really need a working LOP gauge, even a home built one, to get a good measurement.
