Great add on for my T300. It also fits the Redfield Drive HD pump shotgun. Easy installation and well made. Original Tokarev magazine spring seems to work fine with extra rounds. Very pleased!

Seems weird that this is one of the only companies making the magazine tube extension. Definitely worth the money. Makes the tube the same length as barrel. Just add a clamp and visually it's amazing. Better yet it functions too! Half the cheap guys just block the tube or make it so you can't add the extra on. Great work guys!

Fit and finish are done well simple installation functions as it should.

Fit well easy install.

You have to make concessions when installing this. Every time you field strip the gun, this must be removed (instead of the stock cap) and you must control the magazine spring from flying out. The stock spring works fine with this and you get an added bonus...7 rounds of 2 3/4' shells will now fit in. Much better than the measly 4 with stock. I would upgrade to the Wolf Spring since you will be taking the gun apart often for cleaning and they are worth the money. They should have just finished off the end of this instead of leaving it open with the plastic stopper inside, but that combo works fine. (Be careful not to lose that plastic plug as it may slide out on you.) The sling swivel can be removed if you want for a cleaner look. With this tube installed, you get an aggressive looking gun with 7+1 room clearing capability like a Benelli M4. At the bargain price this goes for, it is definitely worth getting.

Good product, wish it was closed on the face of the tube but good for the price

Ordered extension for Tokarev TTS 12ga 18.5in Semi Auto shotgun model which is not listed on website. Extension fits with removal of sling mount. Have 250 rds through tube works flawlessly so far!

Easy install, and works great.

Easy to install and good quality. The existing spring works fine no need to purchase a new spring
