Heavy duty rings - Swift Tactical Low Rail Scope w/ Rings

These are heavy duty rings. six screws hold caps, heavy hex head nut attaches to rail. These are carbon steel and no worries on whatever you mount on caprail. 1inch tube or 30mm with inc. spacers. great price. Low height works for most Scopes. 4-16-50mm millet on savage 300 win. mag. low rings just a little over 1/8 clearance.had to use med. height 0n 4-16-30mm on FNAR due to a long rail. scope touched hard with low about 5/16 clearance. Hope this helps. Note: These are heavy well made rings. If you are trying to keep the weight off these may not be for you, their are lighter ones out there. I have not used a more solid set of rings.
