I WILL NOT BE ABLE TO DO INSTALLS ON THESE UNTIL OCTOBER 1ST. I AM SHOWING THEM OUT OF STOCK AS I DO NOT WANT YOUR SLIDES SETTING IN MY SHOP FOR 3 WEEKS. I WILL OPEN THESE BACK UP FOR ORDER LAST WEEK OF SEPTEMBER. Fits all Buckmark Models. CNC machined from aircraft aluminum and cerakoted for a fantastic lasting finish. this slide racker will not change the weight or function of the slide. The purchase of this slide racker includes installation in my shop. The installation will require some machining on your slide. You will need to mail your slide via US Postal Service to PO Box 4320 Fort Smith AR 72914. I will install the racker on your slide and return ship to you usually within 5 days. If you have the machines or wish a local gunsmith to install then use discount code "I will install" at checkout and $39.00 will be deducted from the price and I will ship the slide racker, screws, and instructions to you. I will not refund shipping if you decide you can not install locally.
