Our copper .45 caliber gas checks are commercial quality and made in house. We make these using a .017 thick 210 copper alloy also known as gilding brass. These .45 caliber gas checks are a true .080 tall, not the .070 you find with some other brands. They fit tight on .426 shanks, the overall diameter is .460 or better.
The checks are sold in resealable clear plastic bags. Shipping is based on each item's weight. USPS flat rates are calculated in the shopping cart. USPS flat rate boxes and First Class mail are used to reduce shipping cost. Most orders ship in one business day Monday - Friday.
Sold in 3 quantities: 250 for $10.50, 500 for $17.00 and 1000 for $30.00.
