Boba Debt 350 Posted October 18, 2009 Report Share Posted October 18, 2009 Today I start my S-12's long conversion to becoming the sweetest bull pup to grace this forum. When I am done, it will look like Kalashnikov and I conspired to create the ultimate close combat shotgun I am starting with a 22" S-12 I bought from Gunbroker for $449 shipped Because I can't do all the work at one time I have divided the project up into 3 phases. Phase 1: The basic conversion in which I will add the following parts: Tapco FCG Tapco Plate Retainer Tapco SAW Pistol Grip And this Flash Hider For phase 2, I'll send the gun to Alex and have him shorten the barrel to 18.5" including the flash hider and I might have him add one of his mid barrel brakes if I think the S-12 kicks too much. Phase 3 will be the most difficult. I have a K-var AKU-94 Bull Pup kit but I plan to replace the forward grip/trigger section of the kit with a Chaos Extended Quad Rail. I really hope the bottom section of his quad can be modified to hold a trigger and pistol grip but if it can't I can have a simple grip section machined locally. This is a long term project but I have high expectations for it. 1 Quote Link to post Share on other sites
thereisnospoon 1 Posted October 18, 2009 Report Share Posted October 18, 2009 Do you have details as to the trigger linkage? I am considering doing this to my 22" .308 I love bullpups, ever sinced I owned my first Bushmaster M17S Need one in .308 without shelling out $2K for a KelTec.

Bvamp 604 Posted October 18, 2009 Report Share Posted October 18, 2009 boba - I am still waiting on the chaos demo mailing to return to my house here. the last one in line said he was mailing it last monday to me. they are a MONTH over due for mailing them. I know ill get the parts back, but I just wish people would consider "timetables" and "agreements" when they say yes. Now im the one sitting here with my d$5k in my hands, looking like an idiot.

I did some research and agree that the G-36 handle would look better and have a lower profile BUT I can't find a real part, all I seam to get are air soft parts when I do a web search Edited October 19, 2009 by Boba Debt 1 Quote Link to post Share on other sites

Boba Debt 350 Posted October 19, 2009 Author Report Share Posted October 19, 2009 Thanks for the info. It a touch pricey but I just might go for it. Will that 3X magnifier work with the HK-93 front sight? Here ya go: [EDITED] 1 Quote Link to post Share on other sites
Death_Delirium 7 Posted October 19, 2009 Report Share Posted October 19, 2009 I like your mock up of it, I look forward to seeing you post pics of the finished product someday. Quote Link to post Share on other sites
Zambidis 90 Posted October 19, 2009 Report Share Posted October 19, 2009 I might have him add one of his mid barrel brakes if I think the S-12 kicks too much. I'm not sure I would want a mid barrel break on an bullpup even if it could be made to work. The S12 is a very soft shooting shotgun anyways. Quote Link to post Share on other sites
negev5021 25 Posted October 19, 2009 Report Share Posted October 19, 2009 (edited) Thanks for the info. Will that 3X magnifier work with the HK-93 front sight? I don't think so. But I don't think the AR carry handle will work with it either. The g36 optic can swap with the SL8 flat rail when BUIS are desired, but not that quickly.... I have the dual optic model, which actually has a built-in post/notch at the top for back ups, which are useless with the dual model since the red dot covers the view, so my assumption is the non-dual model allows you to view the sights on top clearly...

BpS12 512 Posted October 19, 2009 Report Share Posted October 19, 2009 Nice , I'm looking to redux mine this winter. Look forward to seeing your end mod. Quote Link to post Share on other sites
Azrial 1,091 Posted October 19, 2009 Report Share Posted October 19, 2009 I think that a Mid-Brake Comp would work just great on a bullpup, more so because the hot gasses would be using your face as an impingement point... You must be a lot tougher man then me! Muzzle rise is not as big an issue on a bullpup as the muzzle blast exerts less leverage because of the shorter distance to the fulcrum point. 2 Quote Link to post Share on other sites

You must be a lot tougher man then me! LOL just what I was thinking. Some people complain about the blast from an 8" gun with a Shark Brake...I can only imagine the a mid-braked bullpup. 1 Quote Link to post Share on other sites

pedal2alloy 206 Posted October 30, 2009 Report Share Posted October 30, 2009 I'd forget the carry handle altogether. An optic can be mounted directly to the rail, and also it has been proven that nobody uses a carry handle to carry a rifle. Quote Link to post Share on other sites
Boba Debt 350 Posted October 31, 2009 Author Report Share Posted October 31, 2009 If I go with the G-36 handle, my decision will be based on its usability as a "handle", the 3x scope is just a nice side effect. I'd forget the carry handle altogether. An optic can be mounted directly to the rail, and also it has been proven that nobody uses a carry handle to carry a rifle. 1 Quote Link to post Share on other sites

Boba Debt 350 Posted November 6, 2009 Author Report Share Posted November 6, 2009 The G-36 Carry Handle/Scope is a no go. It is way too long and the handle portion sits too far forward. 1 Quote Link to post Share on other sites
Boba Debt 350 Posted November 9, 2009 Author Report Share Posted November 9, 2009 (edited) I had an epiphany about how to modify the G-36 handle to make it fit and it is going to work after all. You guys are going to shit when you see the test fit pictures. I should be done by this week end. Edited November 10, 2009 by Boba Debt 1 Quote Link to post Share on other sites
mechsterbator 0 Posted November 11, 2009 Report Share Posted November 11, 2009 i've shot an SL8 with the optic rail on it, identical to that one. it was difficult enough to use with the rifle, not sure why, maybe because it's tiny. just saying... because it does has the "cool" factor. however, as far as practicality for a shotgun goes, not sure what it has. maybe if you leave your barrel at 22" or thread it and use a paradox choke with some slugs. even then, iron sights or a red dot sight would work just as good.

mechsterbator 0 Posted November 12, 2009 Report Share Posted November 12, 2009 just more constructive criticism... don't take any of it the wrong way. just my two cents. if you were thinking about using the optics rail as a carry handle, take in consideration the balance of the shotgun. most of the weight is to the rear of the shotgun, where the receiver / magazine (where a loaded mag will weigh quite a bit). a lot of firearms that have the carry handle are balanced pretty well. in this case, it might even be uncomfortable to carry it by the handle.

Boba Debt 350 Posted November 12, 2009 Author Report Share Posted November 12, 2009 I was able to test fit most of the parts, I still need to add a Forward Assist Grip. I also have to decide if I want to modify the pistol grip to allow for a rock an lock mag change or incorporate a mag well. I'm leaning toward the later The LOP is 17", the eye relief on the scope seems to be perfect and the handle is in the perfect, without a mag inserted it's just a little front heavy. It feels awesome when shouldered. The silver section is aluminum u-channel, the overall shape is correct but the final part will have slotted venting and more of a contoured look. Here is an image, the only photo shop mod was to shorten the barrel to it final length. 3 Quote Link to post Share on other sites

Nailbomb 10,221 Posted November 13, 2009 Report Share Posted November 13, 2009 Wow, your a lot further along than i thought from reading the posts. Looks nice so far, but i have to wonder about eye relief... you don't have much if any, and with 12ga recoil you might be getting a nice shiner from it. or are apearances decieving? or are you addressing this already?

Boba Debt 350 Posted November 13, 2009 Author Report Share Posted November 13, 2009 I have about 3" of eye relief. Considering that I will only use the scope for 2 3/4 slugs, recoil shouldn't be an issue. Wow, your a lot further along than i thought from reading the posts.

BpS12 512 Posted November 13, 2009 Report Share Posted November 13, 2009 You got 3" of eye relief? Ok if you say so. My scope sits much farther forward and may have 2-3" for relief. We're using the same butt, save mine has a Limb Saver pad on it adding about 2". Good luck. 1 Quote Link to post Share on other sites
negev5021 25 Posted November 13, 2009 Report Share Posted November 13, 2009 I still need to add a Forward Assist Grip. Glad to see the carry handle worked! Looking good. Ever see a Monolith arms forend? May be hard to come by, but may fit your needs.... Quote Link to post Share on other sites
Garys4598 1,065 Posted November 13, 2009 Report Share Posted November 13, 2009 (edited) You got 3" of eye relief? . . . +1 to what BpS12 was implying. I'd really like to see a photo of you shouldering this bullpup S-12 in its present configuration. With what you've shared via your last photo of this work in progress, I'm thinking you are way-off on the eye-relief that you are able to obtain. . . providing of course, you mount that weapon to your shoulder appropriately. I think you need to go back to the proverbial drawing board on this and change some of the dimensions. Nonetheless, good luck to ya; it's a terrific idea.
