A: I have not found where anyone has added a extension. I suggest that you contact RIA and see if they can assist you a good machinist should also be able to make a adapter so you could use one from a Remington or Mossberg contact for RIA Phone: (775) 537-1444 Fax: (775) 751-4425

A: You must remove inner spring retention ring by trimming about 1/4" of threads and Benelli Nova tube extensions will thread right on. No cycling issues for me. GL!

A: John, this 12GA shotgun operates with an inertia style action and not "Gas Piston". Inertia operation involves a bolt carrier and inertia spring that are not rigidly fixed to the rest of the gun. When the gun is fired, the recoil pushes the gun backwards against the inertia spring and bolt carrier that are effectively floating in space inside the receiver. This rapid recoil impulse hits hard enough and fast enough to compress the inertia spring about 4mm, but because the spring is so incredibly stiff it's still able to store enough energy to send the bolt flying backwards where it will compress the return spring while extracting the spent shell and re-cocking the hammer. ****Because inertia guns don't need to hide any gas pistons or external linkages they tend to be thinner and less bulky than gas guns. ****

A: John, the light piston is designed for lighter loads such as target loads, low-recoil loads, and most other common loads while the heavy piston is for more powerful loads such as most 3 inch shells, slugs, magnum turkey loads, etc. (Technically the light piston is intended for load pressures up to 750 bar if that information is available to you) It may require some experimentation with different loadings to see which piston gives the most reliable operation since there are so many different loads available. In reference to James G's answer, there is some confusion as to the operating system of this gun; it is listed as inertial driven but does have a piston part that is nested over the magazine tube where the barrel band sits over it.

A: there are no gas pistons in this shotgun it is a inertia gun

A: Michael, 2nd "Extension" is correct. It won't be 100% flush but close.

A: Anthony, Kyle in one of the reviews added a Benelli Nova/SuperNova +2 mag. Tube extension. His details [The small magazine was my only concern, but I have a Benelli Nova/SuperNova +2 mag. tube extension that fits perfectly and doesn't extend beyond the muzzle. All that's required to install is stripping the gun, degreasing the mag tube and donning heavy leather gloves to get good traction, then unscrew the tube. With the old spring removed you can file off the ledge that retains the spring seat on the end of the tube, then screw on the extension, install the new spring and you're done. You now have 6+1]. --- The Benelli Nova SuperNova +2 extension can be found here : https://www.ebay.com/p/BENELLI-Nova-Supernova-2-Tube-Extension-Super-Nova-12ga-Two-Round-12-Gauge/1381898801

A: Anthony, they should work just fine. Just don't go with an extension tube more than 2 inches or so past the end of the Choke Tube.

A: Anthony, Yes most will work. Just don't go with an extension tube more than 2 inches or so past the end of the Choke Tube.

A: Anthony - The Benelli "+2" will work, but you'l have to file away/remove the 'ledge' in the end of the original magazine tube to allow the spring room to travel the entire length of the tube and the extension. If you have a Dremel you would be in business. There is no 'drop in' extension available that I have ever been able to find.

A: Sebastian, no Sir. Semi Auto's have part of the recoil mechanism built into a portion of the Stock whereas Pumps Shotguns do not and can support Adjustable Stocks.

A: Sebastian, Not on this shotgun. A pump action shotgun okay.
