Carlson's Shotgun Magazine 12ga Extension Assembly

I bought this to add capacity to my Winchester 1300 as much for hunting as to give me another defense option. It was easy to install, although I'll say the new spring was quite a bit longer than the old one and took some work to get it in and get the cap on. Another set of hands would have helped. Looks good though.

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.

I bought the 4506 (6.25” extension for Remington 870 Express) to use on a Turkish made USSG/SAR ARMS, SARSASP to change the magazine tube capacity from 5 to 7. The barrel to tube clamp also has a screw head that can mate with a quick detachable swivel. Shipping was expedient in 3 days through USPS. I would recommend thecountryshed.com to my peers.
