No battery life boost. But, ANY important optic or battery powered gear (flashlights, range finders, lasers etc) use lithium batteries as one day you will
open up your device and find a $1.00 run-away-alkaline energizer has chemically destroyed a $5000 schmidt & bender battery compartment. Don't be battery cheap.
Looks like it’s been mounted before, personally it wouldn’t bother me. Id check the barrel extension, pistons and choke for sighs of use, if so then that’s another story.
I just installed your 3 position tube I purchesed off ebay a couple weeks ago. Feels really nice, I wish I had seen your website before I got mine from eBay and saved me a couple bucks but oh well.
The only issue I had that delayed the install process was not being able to get the flexible ring out of my old recoil tube.
I had to order one, luckily they were in stock at Midwest Gun Works. If you offered these with your new recoil tube it would sure help out with installation.
Midwest part number is 70071 ($5) Freedom Fighter Tactical is $22 wtf? Lol
