There has been some feedback that the Remington 1100 - 11/87 shell catcher is too short/tight to snap over the ejection port. The ones I have sent out are 1.1625" from the ejection port to the loading port. If it's too far off then you will need the 1.2015" version. Please reference the photo. If you need the larger 1.2015" version, please email me for assistance. Moving forward there will be a choice between the two sizes based on your receiver for the 1100 and 11/87.
