JWH223 2 Posted January 14, 2014 Report Share Posted January 14, 2014 Hello, I am new to the MKA 1919, but recently purchased one and have done all the great mods. I just wish it had a shorter barrel, but have too many options floating around in my head, and have already spent mucho $$ to get the gun to it's present state. Here are the options that are going through my head and the positive and negatives of them: 1. Leave it alone...........P = No added costs, has a choke. N = Wish it was shorter. 2. Cut it to 18.25" crown the barrel......P = I can do this for free, I get the shorter look. N = I have no choke. 3. Cut it to 18.25", and have someone bore/thread for internal chokes.....P = get the look I want and still have chokes. N = Costs. 4. Cut to 18.25" and thread the outside myself with saiga threads....P = get the look and can use any/all saga muzzle devices, including external chokes. N = Costs of either buying the die, etc....or cost to have someone do the work. I am leaning towards option 4. Anyone have any input, and anyone know who does the services? I know Tooth and Nail (i have discussed it with them) does the cutting and internal cokes. Wondering if anyone does the external saiga threading. Thanks in advance. P.S. I know I am a little late to the party on the MKA 1919, so bear with me on all my questions and requests Quote Link to post Share on other sites

JWH223 2 Posted January 14, 2014 Author Report Share Posted January 14, 2014 I did read that one, even posted in it. It wasn't really a help with my questions. Quote Link to post Share on other sites
Shandlanos 1,470 Posted January 14, 2014 Report Share Posted January 14, 2014 Looks like you have an AOW in your profile pic. If that's a handgun with a VFG, and it belongs to you - just a friendly FYI, if it isn't registered, that's technically just as illegal as sawing off a shotgun without your paperwork.

No, it's a registered SBR with a folding stock that is folded to the right. But, thank you for your concern. I have a few tax stamps for SBRs. 1 Quote Link to post Share on other sites
XD45 7,124 Posted January 14, 2014 Report Share Posted January 14, 2014 (edited) Perhaps you missed this tidbit since it seems to address your 4th option. Regarding MKA SBS', the barrel is only 21mm in diameter at the 12" - 14" point, so you can't thread it M22 x .75 for Saiga muzzle attachments. It needs to be turned down to 19 or 20mm first, then sleeved, and rethreaded to get it to work with 22mm muzzle devices. Tony Unless of course the barrel gets thicker at the 18" point than it is at 14". Edited January 14, 2014 by Darth Saigus Quote Link to post Share on other sites
JWH223 2 Posted January 14, 2014 Author Report Share Posted January 14, 2014 (edited) I made the decision to cut the barrel to 18.25" It is currently about 1/8" longer, so I have some extra room for cleaning up the muzzle. Turns out the facing tool I have is only .750" Diameter, so I will be ordering a larger 1" facing tool.....of course, they are currently out of stock at midway. Now i just need to decide if I want to thread it externally for saiga threads, or just face it off and leave it. Perhaps you missed this tidbit since it seems to address your 4th option.

It jumps up in diameter for the last 6ish inches. It's all good....I didn't mean any disrespect from my post. Edited January 14, 2014 by JWH223 Quote Link to post Share on other sites
JWH223 2 Posted January 15, 2014 Author Report Share Posted January 15, 2014 Me again......guess I am doing it myself. I am excited! I ordered a Die, die handle and thread alignment tool. Just FYI, I have done lots of threading on my lathe and by hand, I just haven't done anything this large by hand. We will see. If it turns out good, I will post my finished product. If it doesn't, I will run and hide and never be seen again Quote Link to post Share on other sites

Didn't even think to look for a folder on an AR. That's a bufferless .22 kit of some kind? Quote Link to post Share on other sites

Correct....when you run the .22 kit (mine is a stainless steel CMMG) you don't need the buffer and buffer tube because nothing extends past the rear of the lower....actually nothing extends past the rear of the upper. It is an older picture. i have changed the configuration a bit. And, thank you! 1 Quote Link to post Share on other sites
JWH223 2 Posted January 17, 2014 Author Report Share Posted January 17, 2014 Just an update for anyone that may have interest. Some ammo that ran with the full length barrel no longer functions with the 18.25" barrel. This ammo seemed to be right on the verge of working/not working.....now it doesn't work for sure. No loss, I have tested lots of ammo and still have 3 loads that work great that are under $7 a box, and 2 more that are at the $9/$10 a box range. More to come as I get my tooling to thread the muzzle. Quote Link to post Share on other sites
JWH223 2 Posted January 18, 2014 Author Report Share Posted January 18, 2014 I received the TAT (Thread alignment tool) before receiving the Die that I ordered from a different supplier. Looking at the diameter of the TAT compared to the outside diameter of the newly shortened barrel.....it looks like the barrel is on the large side of the range to thread for 22mm. I have a feeling I would end up ruining a perfectly good muzzle without looking at options to turn it down. Info I read earlier made me think it could be threaded without turning the diameter down. Fail on that one. I also ordered the russian style short flash hider made for the saiga. What I ended up doing was true up the face of the barrel after cutting and turned out the threads on the Saiga flash hider. I have a very nice friction/slip fit between the barrel and the flash hider. I plan to use loctite 620 to secure it to my barrel. Basically the same installation ideas as the Tromix shark brake that they make for the MKA 1919. Since my barrel is 18.25" the process of attaching doesn't have to meet and ATF specs on temp, etc. This stuff is supposedly good to 450 degees or so. Hoping my trials and tribulations may help others that have the same ideas. Quote Link to post Share on other sites
