gozuki 3 Posted November 18, 2008 Report Share Posted November 18, 2008 It's the old question, form over function etc. I made up a "tank" brake I modeled after the Barrett because I like the look, but I understand it will have little effect other than weight as far as recoil and muzzle rise. Or mount the "boring" Poly choke? Interestingly, mine is NOT plastic?!?!? Kidding!! So what would be your choice? Quote Link to post Share on other sites
hallboss 1 Posted November 18, 2008 Report Share Posted November 18, 2008 I want your poly choke I've been looking for a brake like that for my AR, it looks good. Mount it up and see if it changes the balance of the gun.... Good work on that, you should sell those. Quote Link to post Share on other sites
cvhanh20 1,052 Posted November 18, 2008 Report Share Posted November 18, 2008 Check this tank break out, it might give you some more cool ideas! Quote Link to post Share on other sites
kingjoey 5 Posted November 18, 2008 Report Share Posted November 18, 2008 Wow, that looks a lot like our KA-0450 brake You'll need bigger ports, shotguns have a large bore, low velocity, and little propellant (compared to projectile weight) so achieving recoil reduction has to be approached slightly differently than you would on a rifle.

lance 4 Posted November 18, 2008 Report Share Posted November 18, 2008 whats it made out of? Quote Link to post Share on other sites
gozuki 3 Posted November 18, 2008 Author Report Share Posted November 18, 2008 You copied my copy of Barrett's copy of a WWII design! KA- I realize it has little recoil reduction, it just looks cool. My ports are tapered 3 degrees, and raked 45 degrees back from the muzzle, I can't tell if yours are also? It is 4140 so I will harden it after I finish it. There was far too much work to sell, other than as a prototype if I don't use it. Quote Link to post Share on other sites
THE_HUNTER 2 Posted November 18, 2008 Report Share Posted November 18, 2008 Polychoke. Most useable. Quote Link to post Share on other sites
6500rpm 670 Posted November 18, 2008 Report Share Posted November 18, 2008 Both! You already have them and you did a nice job. Unless your cutting the barrel and permenently attaching then why limit yourself to one If you are, then shoot them both, then decide. Your gun, your decission.

gozuki 3 Posted November 18, 2008 Author Report Share Posted November 18, 2008 I will be perm attaching whichever one at 18", so I'll put setscrews in each, and shoot them both before I decide. I was thinking I need a couple of ports on top to complete the tank one though... Quote Link to post Share on other sites

There was far too much work to sell, other than as a prototype if I don't use it. We run a 30 degree rake and a gas trap, it improves the efficiency and directs less blast towards the operator. Make sure you soak that part for awhile (probably an hour) when hardening it, there's a lot of metal there and you want it to temper evenly. We build our KA-0450's out of 4340 which is a PITA to machine, I understand your pain. If you look at the price for 'em you can understand the customer's pain as well If you want them threaded, let me know. We have an M22x0.75 bottoming tap here that we use for Saiga prototype parts and I can have our machinist thread it for ya. I might even have some spare lockrings for the KA-1212 that you can use to index your brake. Quote Link to post Share on other sites

I will most likely weld, as it will be at the minimum OAL, and will need to be permanently affixed. I can't stand barrels over about 16" any way, so I'll have to live with 18", as SBS are not allowed in Ca (that are not a C&R)... Quote Link to post Share on other sites

surfmaster 5 Posted November 18, 2008 Report Share Posted November 18, 2008 It would be great if someone could design a muzzle break that screws on to the Saiga 12 threaded muzzle with a break that had forward threads that can accommodate the Poly-Choke. You would have a muzzle brake and a choke together. Barrel Threads + Screw on Muzzle Brake + Screw on Poly-Choke = Recoil/Muzzle Flip Suppression and Ability to Select Pattern Size Still waiting for this item. Quote Link to post Share on other sites

Or mount the "boring" Poly choke? Interestingly, mine is NOT plastic?!?!? Kidding!! So what would be your choice? I like the look of the tank brake, I have a M82A1 CQ (short barrel). How much does it weigh and do you plan to enlarge the ports for reduced recoil? You should try and sell them. I would buy a few. Quote Link to post Share on other sites
G O B 3,516 Posted November 19, 2008 Report Share Posted November 19, 2008 If you are cutting the barrel to 18", bore it for screw chokes, and attach the nuzzle breaks to an extended choke. That way you have many more options. Quote Link to post Share on other sites

Sort of like this but with a comp built in with instead of porting. That would be pretty cool. I'll take useful function over style any day of the week. Style will not save your ass in a real shtf situation. Russian guns are built on that concept. Quote Link to post Share on other sites
gozuki 3 Posted November 26, 2008 Author Report Share Posted November 26, 2008 Picture this about 4" shorter... Quote Link to post Share on other sites
Paladin 37 Posted November 26, 2008 Report Share Posted November 26, 2008 The key is function with great form. I don't care if it looks cool if it doesn't work. Sorta like the cars with fake convertible tops, whats the freaking point!? Your work looks good, how about designing a polychoke feature into a brake? I use a polychoke because it works, if I could get one that looks cool to, then thats ideal! Quote Link to post Share on other sites
gozuki 3 Posted November 27, 2008 Author Report Share Posted November 27, 2008 I could thread for internal chokes easy enough. I could also use the base of the poly, and my brake as the vented portion, and achieve both aims. Good idea! Quote Link to post Share on other sites
gozuki 3 Posted December 11, 2008 Author Report Share Posted December 11, 2008 Decided to permanently mount the poly. Quote Link to post Share on other sites

aessu 1 Posted December 12, 2008 Report Share Posted December 12, 2008 Heh, my saiga has a world's ugliest comp welded on a stock medium choke. Because of the way shotgun things work, comps/ports have to be HUGE to be effective. That's the reason mine has only on chamber, as two-chamber brake would have been simply too big. It's maybe ugly, but it works! yeah, it's only the first version, gonna finish it up and paint etc. Quote Link to post Share on other sites
loner42 6 Posted December 12, 2008 Report Share Posted December 12, 2008 Picture this about 4" shorter... Me likey.........................so did you try a comparison between the two as far as muzzle flip and felt recoil ??? Quote Link to post Share on other sites

Still needs a lot of work, and a friend of mine who knows lot about the way the expanding gases flow has given some ideas about making it better and lighter. Now where did I put my angle grinder and stick welder again... Quote Link to post Share on other sites
