starman 1 Posted February 18, 2009 Report Share Posted February 18, 2009 Why would one use an internal vs. external receiver block when attaching a Tromix stock to a Saiga 12? Other than one being internal and one being external, what is the difference? Quote Link to post Share on other sites
Azrial 1,091 Posted February 18, 2009 Report Share Posted February 18, 2009 The external one hangs out the rear of the receiver and uses the tang for retention. The tang is cut with the internal and most of the stock mounting block is inside the receiver. Most people prefer the looks of the internal, but some people prefer not to cut off their tang. That is it. Name your poison. Quote Link to post Share on other sites
nalioth 405 Posted February 18, 2009 Report Share Posted February 18, 2009 The internal requires you cut the stock tang, for best results. It is also almost 2" shorter than the external (no mods) block. Quote Link to post Share on other sites
corbin 621 Posted February 18, 2009 Report Share Posted February 18, 2009 The main reason I'm thinking of going with an external block is to: 1: Allow the stock to fold with a drum in place..... 2: Keep the tang in case I ever want to go back to a solid stock later. 3: Because of Michigan's stupid law, if the OAL of a firearm is under 30", you have to register it as a handgun. The external block puts it just over that. I personally like the look of an ACE side folder with an internal block or a TROMIX back plate. However, I DON'T want to have to register my Saiga as a handgun, so I'll probably go with the external block. Corbin Quote Link to post Share on other sites
starman 1 Posted February 18, 2009 Author Report Share Posted February 18, 2009 Thanks for the replies. Now I know enough to make an informed decision on what I want!! Quote Link to post Share on other sites
BobAsh 582 Posted February 18, 2009 Report Share Posted February 18, 2009 I don't like the looks of the external block, but I can see using it to achieve a very long trigger pull. Quote Link to post Share on other sites

Looks like what I want to do with mine. Thanks Eric Quote Link to post Share on other sites
corbin 621 Posted February 18, 2009 Report Share Posted February 18, 2009 (edited) Cobra does the rail and cover. You can see the cover here and the rail here. The handguard is from Tromix I believe. As Bob mentioned, you can get a long trigger pull with an external block, though I imagine if you went with a shorter entry length stock, it would be about the same. Not sure though. You need the shorter stock in order to be able to fold it with a drum in place. Corbin Edited February 18, 2009 by Corbin Quote Link to post Share on other sites
BobAsh 582 Posted February 18, 2009 Report Share Posted February 18, 2009 Yeah, that's our handguard. Quote Link to post Share on other sites
nalioth 405 Posted February 18, 2009 Report Share Posted February 18, 2009 I hate to break it to you guys, but a stock doesn't modify the trigger in any way, shape or form. You can get a longer 'length of pull' with the external receiver block over the the internal one. Quote Link to post Share on other sites
BobAsh 582 Posted February 18, 2009 Report Share Posted February 18, 2009 lol yes, "length of pull". I think we all knew what we were talking about. Quote Link to post Share on other sites
