northshorecajun 0 Posted May 12, 2013 Report Share Posted May 12, 2013 I have a Saiga 7.62 with a 20" barrel which I'm going to cut down to 16" and thread it for a flash suppressor. It seems like most folks I see on the internet just use a 14 x 1 LH die and thread alignment tool to accomplish this. However, I've read elsewhere that the maximum barrel diameter for an M14X1 die is 0.560". I measured my barrel with a caliper and it is 0.575". I know that the right way to do this would be to use and annular cutter to reduce the barrel OD before threading. I just wanted to know if anyone had successfully threaded their Saiga barrel using just the die without reducing the barrel OD first. I'd like to avoid dropping $75-100 on the annular cutter if possible, but I don't want to screw up a $35 die and end up having to buy both tools anyway. Oh and I've already decided on a combination gas block / FSB, so a 24 mm threaded FSB is not an option. Quote Link to post Share on other sites
jamesavery22 54 Posted May 13, 2013 Report Share Posted May 13, 2013 The correct procedure is to press out the barrel then cut and thread it on a lathe... You don't have to turn down the OD of the barrel to thread it for M14. It's well within the tolerance for M14x1 dies. Get the TAT from a reputable seller and it will fit the 7.62 Saiga barrel. cncwarrior comes to mind. This process is still easy to fuck up. Dinzag has a threading-for-dummies write up that'd be a good prep read for anyone. Dies are brittle, TATs are easily bent, and people do weird things. Quote Link to post Share on other sites
dubya 198 Posted May 16, 2013 Report Share Posted May 16, 2013 Its not too hard, you want to keep the die teeth well oiled and get a TAT tool from CSS or something it makes the job much easier. I've done 3 barrels and just go nice and slow, you're not in a hurry, and keep the die cool with oil. Quote Link to post Share on other sites
northshorecajun 0 Posted May 19, 2013 Author Report Share Posted May 19, 2013 Thanks for the responses. I know a lathe would be the way to go, but I don't have access to one and I really don't want to press the barrel out. I just wanted to make sure that the barrel OD was within the realistic tolerance of the 14mm die. I was looking at cncwarrior for the die and TAT as well as a an 11 degree crowning tool. Their prices are good and I hear them mentioned frequently so I assume the tools are of decent quality. Quote Link to post Share on other sites
dubya 198 Posted May 19, 2013 Report Share Posted May 19, 2013 I've always bought my dies from CSS but cncwarrior is just as good. Just don't buy any Chinese junk, the metal is crap and very brittle. Ace Hardware (or whatever local hardware store you have) sells threading/ cutting oil and you'll want a small bottle of that too. Quote Link to post Share on other sites
Remek 771 Posted May 19, 2013 Report Share Posted May 19, 2013 also, use cutting oil, if you don't already know. regular oils keep more heat in, and the cutting oils are designed to help get the gunk out while cutting. Hope that helps! 1 Quote Link to post Share on other sites
uzitiger 193 Posted June 1, 2013 Report Share Posted June 1, 2013 I cut off the front sight sleeve then I had to file down the diameter so I could thread the barrel using a standard die. Don't try to use the die with an oversize barrel, you'll ruin the die and still have to reduce the diameter. I didn't take the barrel out nor did I use a lathe. We clamped the front end in a vise covering the jaws then used the die. Make sure you use a left hand thread. M14x1LH. Quote Link to post Share on other sites
sowhat6565 20 Posted April 6, 2014 Report Share Posted April 6, 2014 how did your tap work on the oversized barrel. i am having same issue. cut off shroud and barrel is .568. cnc warrior says this is not in specs for there die to thread and it will not seem to start threading like my newer model guns. just seems to cut down the barrel, not thread it. just wondering Quote Link to post Share on other sites
SaigaFL 4 Posted April 7, 2014 Report Share Posted April 7, 2014 (edited) I've done 3 Saiga AK's muzzle threadings in the last 6 months. The diff between .570 & .560 muzzle OD is not a issue at all. Like the man said do not buy a Chinese carbon steel die. CSS has all the items and gives us members a 10% discount. Just enter CSS at check out time. Go to CSS or You Tube for how to videos. Use 2- 3" long 2x4's with a slight V cut in the middle of the 4" edge. Works great. Edited April 8, 2014 by SaigaFL Quote Link to post Share on other sites
Inebriated 31 Posted April 7, 2014 Report Share Posted April 7, 2014 I just did mine on Friday with a CSS die. Absolutely perfect. Took about 25, 30 minutes. Quote Link to post Share on other sites
Protectandserve 6 Posted June 24, 2014 Report Share Posted June 24, 2014 Can anyone tell if mine is threaded by looking at the muzzle? The FSB is pinned on, no dimples and I can't really tell from looking down the muzzle. Quote Link to post Share on other sites
Rhodes1968 1,638 Posted June 25, 2014 Report Share Posted June 25, 2014 If you cant see threads there is only one way to find out. Quote Link to post Share on other sites
