original bolt body and new bolt handle respectively bolt handle attachment nub 5 is substantially perpendicular to new bolt handle 6 as shown in fig2 amp 3 this structure allows new bolt handle 6 to be operated without interfering with an attached scope attachment nub 5 fits within bolt handle attachment hole 4 such that tension pin holes 7 7 a coincide tension pin 8 is positioned through tension pin holes 7 7 a tension pin hole 7 of original bolt body 1 is perpendicular and operatively connected to attachment hole 4 of original bolt body 1 so that tension pin holes 7 7 a coincide when attachment nub 5 is fitted within bolt handle attachment hole 4 as shown in fig2 attachment hole 4 is drilled into original bolt body 1 at approximately the same location as original bolt handle 2 attachment hole 4 is sized to accommodate attachment nub 5 that extends from the end of the new bolt handle 6 attachment nub 5 is inserted into attachment hole 4 completely and a tension pin hole 7 that is oriented perpendicular to attachment hole 4 is drilled through the bolt body 1 and attachment nub 5 the new bolt handle 6 is secured into place with tension pin 8 that is driven into tension pin hole 7 in one embodiment tension pin hole 7 extends entirely through original bolt body 1 tension.
