Alexc.s. 25 Posted October 18, 2009 Report Share Posted October 18, 2009 I did a bit of searching but didn't find what I was looking for. So this is what I'am trying to understand. How do surefire mags hold the bolt open on the last shot? I looked at my gun and see no way, other than the magazine jaming the bolt. Any one know how it works, or is it some kind of $37.00 magic?

Cobra 76 two 2,677 Posted October 18, 2009 Report Share Posted October 18, 2009 I don't have the SGM mags for my .223 but the ones I have for my .308 work just like the Yugo or Chinese steel AK mags that have a BHO follower. There's a piece on the back of the follower that "jams the bolt" as you say. Take out the mag, the bolt closes.... I use the Bulgarian waffle mags in my .223 conversion. I also have the MSA AR-15 mag adapter and it's nice. You can lock the adapter in just like an AK mag (rock and lock)....then you can straight insert AR mags and they'll drop free when you hit the ambi release. At any time, you can unlock and rock out the adapter, still attached to a mag or not, and switch back to AK mags! Best of both worlds! 1 Quote Link to post Share on other sites
Alexc.s. 25 Posted October 18, 2009 Author Report Share Posted October 18, 2009 Thanks for clearing that up. I think I'll use surefire mags now, and buy the MSA adapter when I get some extra time/money. Quote Link to post Share on other sites
GregM1 241 Posted October 18, 2009 Report Share Posted October 18, 2009 i was using the surefire mags until recently switching to bulgarian "circle 10" mags. They work great. Very reliable. I didnt care for the bho on them but thats a personal preference. It is good for letting the rifle cool down quicker though. Quote Link to post Share on other sites
Cesium 2 Posted October 27, 2009 Report Share Posted October 27, 2009 I use orginal Saiga-223 30rd magazines, which i bought from Russia. Those are 10rd magazines with 30rd magazine bodies, just remove metal thingy that limits the capacity. Those magazines are damn expensive, 50 euros a piece, but in Finland we have shortage of USA made parts because of your crazy gun part importing policies. Quote Link to post Share on other sites

IKE 2 Posted August 9, 2011 Report Share Posted August 9, 2011 Saw this is sticky'd or something so that's why I voted & replied. I use Galil mags. Both Tapco plastic & Steel original 35 rounders. No need to rock them out to remove them, they drop free when you press the mag release on my rifle which is cool. Quote Link to post Share on other sites
josey88 21 Posted October 2, 2011 Report Share Posted October 2, 2011 (edited) I use Surefire mags entirely ... no BHO . Since the Surefires work perfectly , I see no reason at all to install a BHO . My Surefires fit tight and work flawlessly and I even like their looks inserted on the rifle , and yes , the follower stops the bolt open . What I do is I engage the "manual" BHO lever and take out the empty mag so the bolt stays open ... when I insert a loaded mag I rack the bolt a little and the BHO lever recedes and the bolt goes forward , loading a rd ... neat Edited October 3, 2011 by josey88 Quote Link to post Share on other sites
robiejuan 1 Posted October 3, 2011 Report Share Posted October 3, 2011 I like the SGM 100 round drum!! which is a KCI drum with their feed tower! AND the SGM 30 rounders. Both work perfect. Quote Link to post Share on other sites
PinkFloyd 63 Posted October 13, 2011 Report Share Posted October 13, 2011 I run Bulgarian Waffles. Just simpler, dont have to worry about the mag lockback after the last shot, which I think is kinda annoying on a Saiga. Quote Link to post Share on other sites

Nateplaysbass 0 Posted December 1, 2011 Report Share Posted December 1, 2011 Anyone know a good way to eliminate the bolt hold open feature of the surefire mags. I just got one, it is a nice mag, but don't care for the BHO feature. I think I have an idea how to do it, but was wondering if anyone has done this....without messing up their mag.

I wouldn't really call it a feature...more like an un-intended side-effect. I think what you should do is take the follower out of the mag, take a dremel or a file and give the back edge of the follower (right where the bolt hangs up on it) a nice little bevel, so the bolt will ride right over it. If done right, it shouldn't effect feeding at all, and will allow the bolt to close right after the last round is fired. Quote Link to post Share on other sites
Cobra 76 two 2,677 Posted December 2, 2011 Report Share Posted December 2, 2011 This topic should be retitled to read "SGM" mags. There are also Surefire (a different company) 5.56 mags on the market and they do not jam the bolt back after the last shot. Of course these are AR-15 mags, not AK mags, but I'll be finding out soon if they will work with the MSA and Renegade Buck magwells for Saigas. I've now got a Saiga with a TRUE "high capacity" stick mag in it. This one is a 60 rd quad stack, but the next will be a 100 rd. The 60 is only 1 1/4" longer than a 30 rd Magpul P Mag. Going to try and get some testing done with pics and video soon. 1 Quote Link to post Share on other sites
Alexc.s. 25 Posted December 5, 2011 Author Report Share Posted December 5, 2011 Good to hear someone is testing the quad stack, as for changing the topic to read SGM mags I can't edit it. I have no edit button at all, just quote and reply. Maybe due to the age of the topic? Please feel free to change it to avoid confusion with the name change. Thanks.

Nor7 5 Posted March 29, 2012 Report Share Posted March 29, 2012 I actually use both. I can tell the surefire fits tighter but so far I haven't had any issues with either. I have heard that the ProMags have a little piece that chip off but mine are still in one piece. Quote Link to post Share on other sites
Brian M1 50 Posted May 30, 2012 Report Share Posted May 30, 2012 I use Surefire mags. I don't mind spending a bit more on them as they have a great rep, are reliable, rugged enough, and they FIT well. As to SHTF senarios or anything like that, I don't really care. My pistol uses proprietary mags (Glock mags ONLY for me), so why not the rifle too? With so many people saying their rifle works with many different mags WHEN they customize them to fit... WHEN does one have time to "fit" mags in such a senario? My philosophy is get a bunch that you KNOW work, and have used, and stick with them. Just my .02 Quote Link to post Share on other sites

VASH1456 0 Posted August 16, 2012 Report Share Posted August 16, 2012 That damn open bolt feature on the surefire mags nicked my bolt and made it leave deep groove like scratches across the bullet casing when the charging handle went across the bullets. I had to file the chip part down and file a 45 degree angle so that my bolt wouldn't catch anymore. Also, I couldn't put all 10 rounds in the mag. If I did, it wouldn't lock into place. I had to sand the bottom of the follower and cut a 1/2" off the bottom plastic peice so that I could fit 10 rounds in and have the mag click in my gun. Quote Link to post Share on other sites
