M14-PIG 2 Posted December 17, 2010 Report Share Posted December 17, 2010 Hello! Its my first post here. I just joined the Saiga club about an hour and a half ago. I got a 5.45, and much to my surprise, I have a round trunnion. I was under the impression that ALL 5.45 Saigas had flat trunnions. Is this something I need to be concerned about?

Mullet Man 2,114 Posted December 17, 2010 Report Share Posted December 17, 2010 (edited) I have no clue when it comes to the round vs. flat trunnion in the iz240's. If it runs good like it should, then you have nothing to be worried about! What year was yours made? (first two numbers in the serial) Congrats on your purchase.

M14-PIG 2 Posted December 17, 2010 Author Report Share Posted December 17, 2010 Looks like it was made in 09. Quote Link to post Share on other sites
essohbe 47 Posted December 18, 2010 Report Share Posted December 18, 2010 Same here. Are you getting a bullet guide? Quote Link to post Share on other sites
SgtRaven 531 Posted December 22, 2010 Report Share Posted December 22, 2010 Got mine last week from the "fresh pool": round trunnion as well. I will put a bullet guide soon,, as a part of conversion (I've got to have my pistol grip!). Quote Link to post Share on other sites
rs51085 136 Posted December 22, 2010 Report Share Posted December 22, 2010 I have a round one as well I just got. I bought a flat bullet guide with out looking first because I thought they were all flat also. The good newas is I have about 100 rds through it with bulgy circle 10 mags with no malfuntions. It suprised me that it feed that good with out a guide. Quote Link to post Share on other sites
geepelton 105 Posted December 22, 2010 Report Share Posted December 22, 2010 Mine is in the mail and should be here tomorrow. It will be a nice addition to the S-12 and Mosin Nagant. Quote Link to post Share on other sites
SgtRaven 531 Posted December 23, 2010 Report Share Posted December 23, 2010 Anyone tried Bulgarian round guide from K-Var? I am very tempted, as it looks like a perfect fit. (I'd use machine head screw instead of rivet). http://www.k-var.com/shop/product.php?productid=16321&cat=281&page=1 Quote Link to post Share on other sites
7N6Wolf 61 Posted January 16, 2011 Report Share Posted January 16, 2011 Same here. Are you getting a bullet guide? I am still thinking about this. Mine feeds flawlessly from AK-74 magazines without a bullet guide, but I will remain open to the idea of installing one, as I have not fired my Saiga 5.45 extensively yet (I have only put 150 rounds through it thus far). My Saiga 5.45 was made in 2009 and appears to have a flat trunnion. Quote Link to post Share on other sites

My Saiga 5.45 was made in 2009 and appears to have a flat trunnion. After evaluating both guides, I've decided to go with Dinzag's (kit with guide, screw, allen wrench, drill bit and tap). Fits like a glove and easy to install. "Bulgie" above required dremmeling I didn't care for. Still keeping it for spares. However, 250 rounds with Tapco mags before any guides and no jams...

BigChongus 765 Posted January 20, 2011 Report Share Posted January 20, 2011 Is it possible the the round BG for the 7.62 would work in the 5.45? Quote Link to post Share on other sites
BigChongus 765 Posted February 5, 2011 Report Share Posted February 5, 2011 Re my last post, now that I have the 5.45 and 7.62 side-by-side, I'm pretty positive that the 7.62 round BG will work in the round-trunnioned 5.45s. I don't feel like pulling the guide out of my 7.62, but I've got a second one on the way for the 5.45 to test the fit/ function on. Quote Link to post Share on other sites
SgtRaven 531 Posted February 6, 2011 Report Share Posted February 6, 2011 I ended up dremmeling my Dinzag round BG (was too flat and being hit by bolt). That threat is here; hope your experience will be different: http://forum.saiga-12.com/index.php?showtopic=61343&pid=599545&st=0&&do=findComment&comment=599545 Quote Link to post Share on other sites
BigChongus 765 Posted February 6, 2011 Report Share Posted February 6, 2011 I'm using CSS guides, so hopefully that makes a difference. I've got almost 300 rounds through my 7.62 without a single jam using the CSS guide. No wear marks, either. Quote Link to post Share on other sites
tStreets 1 Posted February 7, 2011 Report Share Posted February 7, 2011 I have a rounded trunion produced in March of 2009 and ordered in Dec. of 2010 from Mississippi Auto Arms. If you think about the flat vs rounded trunions and the path of the 5.45 round to the chamber, it almost makes sense that the round trunion is better suited to "ramp" the round more efficiently into the chamber vs the flat trunion. Reason being that the cartridge has a higher "ramp" with the rounded trunion vs. the flat trunion? Either way, I'd rather have a round trunion vs a flat trunion... Just how I like my women...

BigChongus 765 Posted February 10, 2011 Report Share Posted February 10, 2011 Success. The CSS guide fits the trunnion perfectly and doesn't contact the bolt at all. Quote Link to post Share on other sites
SgtRaven 531 Posted October 18, 2011 Report Share Posted October 18, 2011 (edited) Just got CSS' bullet guide for new project (.223 conversion), and it fits like a glove. New purchase, but rifle made in 2009; round trunion. Edited October 18, 2011 by Sgt. Raven Quote Link to post Share on other sites
joek4061 6 Posted October 19, 2011 Report Share Posted October 19, 2011 I'm not going to swear by this but; I believe the extra shoulder on the K-VAR bullet guide is there to rotate the bolt into lock up. The Saiga has a little bump that is built into the receiver that rotates the bolt. The original Bulgarian bullet guide would most likely not fit in a Saiga. If you look into your rifle you will see the bump I am referring to. It appears to be placed in the same position as the shoulder on the Bulgarian guide. Quote Link to post Share on other sites
SergeK 15 Posted October 19, 2011 Report Share Posted October 19, 2011 Yeah there is no point in getting the bulgarian guide unless you want to grind off that locking shoulder. Quote Link to post Share on other sites

DLT 1,646 Posted April 13, 2013 Report Share Posted April 13, 2013 I used a CSS in my conversion. Has worked flawlessly. Quote Link to post Share on other sites
Landis 3 Posted April 13, 2013 Report Share Posted April 13, 2013 What does Arsenal use in their SGL 31 conversions? They seem to have a good reputation. Quote Link to post Share on other sites
thebuns1 4,323 Posted April 13, 2013 Report Share Posted April 13, 2013 What does Arsenal use in their SGL 31 conversions? They seem to have a good reputation. They're not conversions, but they use the current bullet guide that goes into the Russian AK-74M and 100 series that is riveted in. 1 Quote Link to post Share on other sites
t165 30 Posted July 9, 2013 Report Share Posted July 9, 2013 I know this thread is 3 months old but the topic did make me curious how the bullet guide in my 09 built Arsenal SGL 31 was designed and attached. A picture speaks a thousand words. 1 Quote Link to post Share on other sites
amd6547 2 Posted July 10, 2013 Report Share Posted July 10, 2013 My 5.45 Saiga has the flat trunnion. It also seemed to work fine using Bulgarian polymer 30rd mags...never a jam. I wasn't sure about putting in the bullet guide, since it worked so well without it However, when I did my conversion, I installed the CSS bullet guide. After going to the range, I had to admit that while racking the bolt, feeding felt smoother...noticeably smoother. Quote Link to post Share on other sites
