BuzzSaw 0 Posted November 16, 2010 Report Share Posted November 16, 2010 I am very interested in doin a Draco SBR, but I am curious as to what is involved in the stock conversion. I havent really looked closely at a Draco and was wondering how you put the folding mechanism on the receiver. Is there a plate put on at the factory that you take off?

22_Shooter 1,560 Posted November 16, 2010 Report Share Posted November 16, 2010 This guy.. http://forum.saiga-12.com/index.php?showtopic=58773 ..says he's more than confident in his drilling/tapping directly into the rear trunnion to mount the folding mechanism. No, there's no plate or anything you take off. Draco's come with an underfolder rear trunnion that hasn't had the holes put in for the underfolding parts. It's a smooth-backed trunnion that people prefer to just drill/tap directly into. Some put nuts on the back side of the screws of the folding mechanism, inside the receiver, for more security.

macbeau 902 Posted November 16, 2010 Report Share Posted November 16, 2010 You can just drill and tap the trunnion and put on an ACE stock (or ACE-style, with or without folding mechanism). The back is more than 3x as thick as the sides are (that you can see inside the receiver). Mine measures about 9.5mm at the back. The sides that you can see insire the receiver are about 3mm thick. It is also hardened and you'll need a good sharp bit and tap and lots of cutting oil. Also - take extra effort to mark your holes before you drill them. I drilled and tapped mine and added screws long enough to protrude through the inside the receiver about 3/16" and added star washers and nut and blue locktite. I think this was probably more than necessary and I am satisfied that the weak point is the mounting screws and ACE aluminum folding mechanism. That trunnion is a strout piece of steel. I am still debating on adding a cross rivet and bushing to strengthen the forward portion of the trunnion in the receiver. I'm not certian it needs it and I hate extra holes (or rivets) in my rifles... Macbeau sends... Quote Link to post Share on other sites

I'm curious what the accuracy is like now that there is a stock on the rifle. Quote Link to post Share on other sites

I did a range report about 6 weeks ago and posted it here: http://forum.saiga-12.com/index.php?showtopic=58773 I was pretty impressed with the accuracy. I think it would greatly benefit with a receiver-cover mounted rear sight (A'la Galil / Valmet) as the sight radius is (and sight positions are) about the same as an 8" barreled pistol. The longer sight radius would help. Macbeau sends... Quote Link to post Share on other sites

Where did you get the Galil handguard and what did you need to do for it to fit? I guess this will be my next project!

Also, can a standard scope rail be installed on the Draco? Thanks! I used an IMI, black polymer handguard and an IMI .223 AR rear handguard retainer. (you can use a .308 AR retainer, but it'll be loose) and shortend the front metal on the handguard via a file a mm or so... You also have to trim (file) the plastic that sticks out of the back of the retainer to be flush with the retainer/receiver. It's not a hard task at all. I used the stock Draco front handguard retainer, unmodified. The Galil AR foreend is pretty sweet and very tight on the rifle. It also allows for great airflow around the barrel and gas tube and has a very substantial heat shield inside. Macbeau sends... Quote Link to post Share on other sites
