1911sig 3 Posted January 1, 2015 Report Share Posted January 1, 2015 I have not seen many options out there if you want to have both. Or am i missing something. if you are running a choke and brake what are you using and how do you like it Quote Link to post Share on other sites
RED333 1,025 Posted January 1, 2015 Report Share Posted January 1, 2015 Yep, takes a bit of work and money. Get you a die and chokes you want. Get an adapter to screw onto the barrel and allow you screw the choke on. Thread the choke to screw on you brake. I have have diff chokes done this way. This is the adapter I use, rifled choke With the GK-01 IIRC the adapter is from Cobra, member and vendor here. Quote Link to post Share on other sites
burntpowder 23 Posted January 2, 2015 Report Share Posted January 2, 2015 (edited) I went this route (the modified one) and a JT Engineering Competition Brake and am please with it. http://www.carolinashooterssupply.com/product_p/sgm-choke-adpt-modified.htm http://www.carolinashooterssupply.com/product_p/sgm-choke-adpt-full.htm Edited January 2, 2015 by burntpowder Quote Link to post Share on other sites
MLM0358 107 Posted January 2, 2015 Report Share Posted January 2, 2015 I've done a ton of experimentation on just this issue. Bottom line -- the best way (though not the cheapest) is to cut off the end of the barrel, internally thread the barrel for chokes. I then silver soldered on a bushing. Used machine screws to hold the comp to the bushing. Made a long tool to reach inside the comp to change the chokes. I've tried all sorts of methods, but this is by far the cleanest and lightest installation. You can cut at 18" and have the comp sticking out further -- or cut off at 16" and permanently affix the comp. I've found you can go to 16" without modifying the gas system. Some notes in other threads on this. The bottom picture shows two more methods. The left one uses a choke adapter that threads on the barrel, the comp slips over that (BTW -- i have an extra choke adapter - PM me if interested).. The right one uses a homemade compression fitting. When the six allen head cap screws get tightened, it compresses a taper against the barrel. Elegant, but too much work. 2 Quote Link to post Share on other sites
MLM0358 107 Posted January 2, 2015 Report Share Posted January 2, 2015 Oh yeah, here's another method I tried. This comp mount is aluminum so it's not as heavy as it looks. However the silver soldered bushing I mentioned in my last post eliminates all the clamping to the muzzle, hence the light, clean installation. With each method I use a long tool to change chokes so no need to remove the comp. Quote Link to post Share on other sites
pedal2alloy 206 Posted January 2, 2015 Report Share Posted January 2, 2015 This has been done by some guys on the board You can have your barrel threaded for internal chokes and then bore out your brake sufficient enough for an extended wrench and the chokes to go thru. The brake would need to be welded or soldered on because the barrel wall wouldn't have enough thickness to also thread the outside. Quote Link to post Share on other sites
1911sig 3 Posted January 4, 2015 Author Report Share Posted January 4, 2015 (edited) Thanks for all the input i think i am going to go with the choke that has threads for a brake for now Later i will shorten the barell perm mount a brake and internally thread for changeable chokes Edited January 4, 2015 by 1911sig 1 Quote Link to post Share on other sites
saltydecimator 482 Posted January 4, 2015 Report Share Posted January 4, 2015 (edited) gotta machine shop in the basement malcom? i digit.... really, chokes are all ya need. the physics of it all means that any given "brake" doesnt do much. brakes are for hi pressure sitches, and 12ga is just not that. rifle pressures are what like 50-70k psi? 12 ga is like 20-30k max, if not more like 15k. i forget the numbers.... this will do what you want. i think. has slots for fh when its not bein used as choke. nifty, if not slightly pointless??? imo http://www.carolinashooterssupply.com/product_p/dph-choke.htmf Edited January 4, 2015 by saltydecimator 1 Quote Link to post Share on other sites
burntpowder 23 Posted January 4, 2015 Report Share Posted January 4, 2015 I cannot disagree with you at all and although I said I am pleased with the Muzzle Brake adapter coupled with the JT Engineering Competition Brake it does make for a long barreled setup. I think (I have all this length info in another post somewhere here) the Muzzle Brake adapter adds 1" to the already 4" JT Engineering Competition Brake (when all are screwed together and on the barrel) so that is at least an extra 5" hanging off the end of a 19" barrel. If anything the added weight to the end of this setup helps with any kind of (perceived or otherwise) barrel climb but as I said, it makes for a long barreled setup and even longer (by one inch) if the CSS GK-01 Brake were to be used (that is 5" OAL itself). -bp Quote Link to post Share on other sites
MReed 0 Posted February 11, 2015 Report Share Posted February 11, 2015 Poly-Choke. One made to screw onto s12 barrel. 4 styles of flash hiding. I have one. I like it. Great product, American company. Sold on this site, and at poly-choke.com company site direct. About $100. Got mine direct in 4 days usps priority mail. Search poly-choke. You won't be disappointed.

MLM0358 107 Posted February 11, 2015 Report Share Posted February 11, 2015 I started out with a poly choke and I agree it's an excellent solution. Problem, at least for me, with poly choke is that it's not as effective a muzzle brake as some of the other options. The challenge in a competition gun is to get a good choke, a good brake, and good reliability all at the same time without a long overall length. 1 Quote Link to post Share on other sites
Fitty% 808 Posted February 26, 2015 Report Share Posted February 26, 2015 (edited) Get either the modified or full choke thats threaded for a muzzle brake from CSS. Edited February 26, 2015 by BLK-HWK-VET Quote Link to post Share on other sites
nizzmont162 0 Posted February 28, 2015 Report Share Posted February 28, 2015 some interesting ideas,i just got my IZ-109 Tuesday and now looking to get all my parts ordered to put it back to the proper configuration and I also want to put a break or breach end on the barrel.thinking about taking it down to 16 inches first since I heard that's a safe number and run factory gas system Quote Link to post Share on other sites

nizzmont162 0 Posted February 28, 2015 Report Share Posted February 28, 2015 yeah i know,im looking for someone around my area to shorten and attach a brake to my barrel Quote Link to post Share on other sites
Wagnikov 186 Posted February 28, 2015 Report Share Posted February 28, 2015 It's gonna cost but if you take it to a gunsmith to shorten, spend the money and have the barrel threaded for chokes. 1 Quote Link to post Share on other sites
