FM 3-22.1a. Mark adapters before screening. Wrap a piece of 1-inch-wide masking tapearound the telescope end of the adapter. Make position marks ("A" and "B") on the tapeto align the adapter in the barrel and the telescope with the adapter. You can use anadapter-marking template for this (Figure B-25). If you use the template, you can alsotape it to your clipboard to hold scoresheets during testing. Place the telescope end of theadapter on the template and on the position marks. Adapters have no permanentidentification marks, so you must add them yourself. Then you must mark anidentification number for each adapter on the tape. The example adapter shown inFigure B-26 is marked with the number "4."Figure B-25. Adapter-marking template.Figure B-26. Marked adapter.b. Begin testing when you have emplaced the vehicle and panel, aimed the gun atthe panel, marked the adapters, and obtained an accurate telescope. The data recordermust have a set of scoresheets and a clipboard.(1) Before testing each piece of equipment, record the date, time, unit, test type,telescope serial number, adapter number, and your name on the scoresheet. Test typeindicates whether tester is checking an adapter, telescope, or kit.(2) Test the adapters using the same kit-rotation procedure that you used for the kitaccuracyfield test. Begin testing with the telescope facing right. Observe and record thereticle's aiming point on the scoresheet. Rotate the adapter and telescope togetherone-half turn (180 degrees), until the eyepiece faces left. Record this aiming point onthe scoresheet.(3) Test each adapter twice. This provides a more reliable estimate of accuracy.Record data for the first test in the TEST 1 section of the scoresheet; record data for thesecond test in the TEST 2 section. The tests differ only in the adapter's position in the gunbarrel. The following describes a sample test:(a) Insert the 25-mm adapter into the gun barrel with the position mark "A"facing right.(b) Insert the telescope into the adapter with the eyepiece facing right.B-18
