I don't have an Elisio, but I do have a MAK tube gun. I don't believe we can get them any more but it is similar.
I like it for two reasons,,,
1) Since the action is glued in, it provides additional action stiffness.
2) The tube gun provides enhanced safety... Seriously... guys need to understand this.
The action I'm using for the MAK is a blue printed Rem 700. In the McMillan fiberglass stock it was in before I had problems with the scope base coming lose. This was caused by action deflection.
If you examine a Rem 700 repeater action, you will see there is actually very little steel in the middle as it is unnecessarily cleared for ejection and for the mag port. This allows the action to bend like a banana under the stress of firing.
So gluing the action into the MAK provided the additional support I was looking for to correct that particular problem.
To my point regarding safety, I came to this realization while ground hog hunting with a friend who is well known for "being careful with money". He bought some reloaded ammo at a gun show and he became an example for why you should not do that.
He was using a Rem 700 Sendero and after he fired one particular shot, he leapt up from the rifle holding his face. He was obviously injured as he was bleeding. He had maybe a hundred little specs all over the right side of his face that were bleeding and he could not see out of his right eye.
Luckily I happened to have a military first aid kit and in it was some eye ointment and eye patch. So I patched him up.
The next thing I did was take a look at his rifle. I was expecting to see some obvious damage, but it looked fine. Then I opened the bolt, and I could see the case had a split along the long axis of the body.
So the brass did not do it's job of retaining the pressure. The pressure blast ran along the lug way on the left side of the action and vented out the back end of the action and into the shooters face.
So, aside from the lesson about buying reloads from a gun show, what does a guy learn from this?
a) Savage is a little smarter than Remington, as the Savage actions have a false lug to block the rearward flow of gas. They also have a purposely designed bolt, that also blocks the flow of gas into the shooters face.
b) If you have a Rem 700 pattern action, you should be aware.
Anyway, enter the Tube Gun solution... Both the MAK and Elisio tube guns provide protection from such an event. Since I mostly shoot F Class, and we are notorious for running hot loads, I appreciate the safety element.
When it comes to PRS, its important to have balance and a flat shooting base just ahead of the mag well. Not sure if Elisio offers such accessories.
