    GrovTec US Extended 12 Gauge Magazine Tube Remington 870 Black MTMx3 GTSW257
    Jan 23, 2020
    Slides along barrel under full power loads
    Pros: eBay price better than retail Cons: 1) Bolt is not long enough to use with included quick release and washer. If you want to use a quick release, buy something else. 2) Bolt hole in clamp is centered between barrel and magazine tube - presumably to work with any magazine extension and to allow mounting at different positions along barrel. However, even when fully tightened the assembly does not stay in place - it slides along barrel due to recoil. During a training class, it stayed in place for 150 birdshot, but once we fired 15 full power slugs and 30 OO buck it had slid just over an inch. Probably would have been worse with a flashlight attached - may have come off. Unfortunately, the bolt hole in clamp was not offset like OEM Remington such that it rides in the magazine extension's groove to prevent sliding. I will either return it, toss it, or I may reuse the OEM clamp (since it's bolt hole is offset to mate with magazine extension's groove) by drilling out the threads in the clamp so the GroveTec bolt can just feed through and into the GrovTec picatinny rail. It still won't work with the quick release, but I don't plan to use it.
