coltgov Posted August 7, 2008 Share Posted August 7, 2008 My Storm Lake barrel has plenty of threads but I did thin down the jam nut so I could get more threads on. Please please please be careful and very diligent when reaming out the comp. Bullet strikes on the comp can make for any thing from an annoying tumbling bullet to a catastrophic failure of the comp complete with metal coming back at you at very high rates of speed. I would highly recommend taking it to someone with a proper comp reamer so they can make certain it has the correct bullet clearance and bore alignment.I doubt the welding would work that would be a boat load of weld on an already heavy piece of steel hanging off the end of the barrel. Depending on how soon Kenny can get the comps done I may throw mine on the mill and put a few top ports off the second two chambers just because I can. I was considering trying to weld a little on the sides of the first chamber just so I could open the top of it as well, but I just haven't figured out how to do is just yet. To weld up the sides of the chamber, just get some round steel stock that fits the gap and weld it. I did that with my LWD comp to make it shoot flatter. To get more threads you can copy the way the LWD comp is machined. Cut the threads from the comps opening so it can go in over the barrel a little. Then drill and tap for a 1/16" 10/32 set screw. You may have to mill the area where the set screw is first so it clears the guide rod. These barrels have a flat at the bottom to secure the Gemtech suppressors with a set screw. Doing this will add a lot of support to the comp so it stays concentric to the bore. Like you said hitting baffes is bad! I'll have JoJo at JV Dynamics do this. Open guns are his speciality. Have said that he could just machine one out of a blank that looks like it belongs! But owning a Glock makes me super cheap! Link to comment Share on other sites More sharing options...
coltgov Posted August 12, 2008 Share Posted August 12, 2008 Just got my AR15 Miculek comp. Instead of the jam nut, I used a peel washer to index it. Also crush washers work as well. They are thin so almost all of the threads on the comp can be used. Having it reamed at my gunsmith at the moment. Now have to see if it is any better than my LWD comp. Hoping it will shoot like a .22 rimfire. Link to comment Share on other sites More sharing options...
Micah Posted August 13, 2008 Share Posted August 13, 2008 Great setup and ingenuity! Carter, if you buy one, you gotta let me shoot it Link to comment Share on other sites More sharing options...
coltgov Posted August 17, 2008 Share Posted August 17, 2008 I got different results for the Miculek comp on my Glock 17. Shot a match today. 6 stages. It is only 50% as effective as my modified LWD major comp. Tack welding a sleeve to plug up 1 side of the Miculek comp this week to make it a top ported comp only. It may be a keeper after that!

coltgov Posted September 5, 2008 Share Posted September 5, 2008 (edited) Finished modifying the Miculek comp today. Works really well! Thanks Dan for giving me the idea to put it on my Glock 17. Here is a pic of what I did to it. Edited September 5, 2008 by coltgov Link to comment Share on other sites More sharing options...
Dan Burwell Posted November 28, 2008 Author Share Posted November 28, 2008 Sorry, I have been fairly busy but here are this pics with the new comp on, the jpoint melted in, and the slide racker installed. The gun is running well after sorting out several little problems. coltgov, I bet that modified mikulek works pretty well. Link to comment Share on other sites More sharing options...

ExtremeShot Posted December 4, 2008 Share Posted December 4, 2008 DarrenWhat thread pattern? How much for the blank? As I recall, the thread was 1/2-28. It's been quite a while since I sent that to Dan. Since it was a one-off custom job I think I charged something like $50 or $60. ....I honestly don't remember. I remember looking up prices for other readily available comp blanks then adding a little more. Maybe Dan remembers what he paid. Darren Link to comment Share on other sites More sharing options...

Darren Darren, I try very hard to forget prices as soon as possible that way when the wife asks I can answer with 100% honesty "I can't remember" so sorry I don't remember. the thread pitch is 1/2x28. I am sure I have the other dimensions around here somewhere. I did find a guy to cut some on a CNC for me with a different port set-up that I am optimistic will work a bit better. So we will see what happens with it. Link to comment Share on other sites More sharing options...
B.J. Norris Posted December 4, 2008 Share Posted December 4, 2008 Dan, Did you have to remove the FP block to melt the J-Point like that? Link to comment Share on other sites More sharing options...
Dan Burwell Posted December 4, 2008 Author Share Posted December 4, 2008 Dan,Did you have to remove the FP block to melt the J-Point like that? No all safeties are retained. You just need a spare hand while installing the Jpoint. Link to comment Share on other sites More sharing options...
