gregomega 929 Posted September 27, 2010 Report Share Posted September 27, 2010 I've been looking around but I could only find 5.45 diameter AK74 24mm style brakes... where do you guys find these for the 7.62? i'm about to punch the gas block and FSB off... I hear it's a pretty painful process (but rewarding) I just put the brake that you speak of on both of my 7.62s. It works fine. I've put 30+ rounds through it already. No problems. $40 from dinzagarms http://www.dinzagarm...kes_hiders.html Ok so after shooting more rounds through my 7.62x39 and cleaning it yesterday, I found something I think would change my previous comment. Have a look. Anyone notice anything wrong here. The chip kindof suprised me. I now have problems and have evidence of the round hitting. Quote Link to post Share on other sites
Cobra 76 two 2,677 Posted September 27, 2010 Report Share Posted September 27, 2010 Cool vids. I would like to see a side by side comparison between a J-Tac and a real 74 brake. Maybe I'll drill one of my 74s out and make a vid sometime shooting next to a cam on tripod. I forgot to come back and post the pics I took of the gouges left from using undrilled 5.45 brakes and thread adapters on my 14mm threads. I would not recommend this. Either get a 24mm threaded FSB or drill the mil spec brakes out first. As far as paying that much extra for an Arsenal brake with a bigger bore...no thanks. First pics shows a 7.62x39, a .223, and a 5.45 round..all three in unmodded 5.45 brakes. 7.62...(5.45 EG Zig Zag Brake) Gouges... Now the 5.45....This how much clearance they designed the brake to have, for the particular round it was meant to be used with...or can someone provide proof that it was also meant to be used with the 7.62 round...not just that you can get by with it on some rifles? SXS comparison... I feel much better about having equal clearance for a 7.62 round, if using the brake on that rifle. That's just me though... Quote Link to post Share on other sites

Im gonna drill mine out tonight. not sure what what size bit I should use though. Wow, your brake has much more damage than mine does. Quote Link to post Share on other sites
rx slim 6 Posted September 29, 2010 Report Share Posted September 29, 2010 I've been watching now for a while, and haven't found a moral to the story yet. If I were to go buy now, who has the best deal. . .and what is the easiest purchase for a Saiga 7.62x39? Quote Link to post Share on other sites
BaylorHenry 5 Posted October 3, 2010 Author Report Share Posted October 3, 2010 (edited) Im gonna drill mine out tonight. not sure what what size bit I should use though. Wow, your brake has much more damage than mine does. I used a .359 dia drill bit. I viced the FSB on before i installed it onto a barrel and just drilled through with the FSB holding it in place. Then I reamed it out a little more with a dremel.... just a tad bit to clean out the burrs, reblued (or cold blue if you like) and voila. I actually also fitted my brake on pretty tight. I started sanding the back of the brake down so that it would index between 11 o'clock and 12o'clock, then stuck an aluminium cleaning rod through the front brake hole and snapped the punger in place. shot it and broke it in a little, now you can hand index it into place and still have it be tight. I've been watching now for a while, and haven't found a moral to the story yet. If I were to go buy now, who has the best deal. . .and what is the easiest purchase for a Saiga 7.62x39? http://forum.saiga-12.com/index.php?showtopic=56800 I bought my stuff from him... pretty fast shipping. I'm going to clarify myself again. I DON'T think the stock 5.45 should be put onto a 7.62. When I got mine it was evident that I didn't have enough inner diameter for the 7.62 to go through. However, between drilling the hole out and stabilizing my brake on, it is working for me and I'm getting 2MOA groupings very consistently. What works for me may not work for you, I think it would, but who knows. Edited October 3, 2010 by BaylorHenry Quote Link to post Share on other sites

freddy g 11 Posted November 14, 2010 Report Share Posted November 14, 2010 Well after about 100 rounds through my bulgy AK-74 brake there are still no hit marks at all! maybe some brakes are smaller hole then others or they dont sit dead center. Quote Link to post Share on other sites
