Carlson's Shotgun Magazine Extension Assembly

Well made, fit my Model 1300 perfectly, extension support clamp is surprisingly sturdy, extension is only about 1/4” longer than my 18” barrel so it looks really good. 4 stars instead of 5 because support clamp should have rubber coated clamping surfaces so it doesn’t harm bluing on the barrel and extension. I used gorilla tape which works. Buyers pay attention, this extension gives you 7 shot TOTAL capacity, that’s 6+1 in the chamber.
