Check the listing for details. Chronograph Shield for Kurzzeit BMC19 / PVM-21 / LS260 (2x Plates). Condition: New. Listed at 100.00 USD. Chronograph Shield for Kurzzeit BMC19 / PVM-21 / LS260. This listing is for TWO BMC19 protector plates. One for each light screen. It's up to youy to mount them and paint them however you choose to. For mine I have a steel crossbar and can supply this to you if you're interested for a small sum. This is 1/2" a36 steel that I had waterjet cut. I am simply trying to defray the cost of the pair of plates I had cut for my chronograph. If you have3 one of these chronos you'll likely agree it is worth protecting. The sale price is 1/2 of what I paid for 4 plates plus a small bit to cover what ebay is going to take off the top. The goal for making this is to enable one to take shots through the chronograph at 100 or 200 yards ... to verify ballistic coefficients, energy trajectory etc without putting one through the instrument itself. ME is lower at distance and I believe the 1/2 plate is good enough for what I'm doing. I make no guarantees that you'll be happy with this or that it will protect your chrono from a bullet fired out of a gun. I believe the two plates will fit into a USPS box. Regards.
