badger1864 Posted August 13, 2013 Share Posted August 13, 2013 I just got my first 12 gauge. After careful research I went with the SuperNovi tactical with pistol grip. This come with a fixed cylinder choke, not sure what that means, can anyone clue me in?? Thanks, also looking for a mag extension so I can be able to add 2 more rounds instead of the 4 the mag holds. Thanks all Quote Link to comment Share on other sites More sharing options...
lrtraut Posted August 13, 2013 Share Posted August 13, 2013 Though I'm not familiar with that particular model and am not an expert, I will try to explain some basics. If it has a fixed cylinder choke, that indicates that the choke is "fixed" and not interchangeable. The choke is referring to a taper of the inner diameter of the barrel at the muzzle thataffects the shot pattern. A cylinder bore choke is essentially the same diameter as the bore and would have a "wider" pattern, while a modified or full choke will have a "tighter" pattern because the diameter is smaller ot "tighter". Typically tactical shotguns use a cylinder or improved cylinder choke. Hope this helps. Quote Link to comment Share on other sites More sharing options...
RC Maroni Posted August 23, 2013 Share Posted August 23, 2013 (edited) You can bing or google shot gun chokes and get a lot of info to read about this. Some shot guns have about 1 inch of a thread on the inside and at the top of the barrell. A partially threaded tube ( usually 5 types) screws in allowing a variety of shot spread.
