USMC1341 36 Posted July 28, 2020 I'm looking for suggestions on a NJ legal muzzle device that can be pinned and welded to a 14.5" barrel (1/2-28 TPI) to get to 16+ inches. I'm leaning towards a KVP or something along the lines of a linear comp vs. a brake. Let me know what you guys have experience with and recommend. Also, it is helpful if you know for sure it'll add the necessary length to reach 16 inches, but I appreciate any suggestions. I can always do math or hound the manufacturer to find out. Also, a second question I'm sure some of you here will be able to answer. I've seen some muzzle devices that are titanium. Can a typical gunsmith weld a titanium device to a steel barrel? I know very little about welding, but it seems like that might be more challenging if not something that can't be done easily. It is however something I might consider to keep the weight at the end of the muzzle down if it's an option. Quote Share this post Link to post Share on other sites

I've seen this setup too, which is getting pricey. https://www.tacticallink.com/griffin-armament-vg6-precision-cqb-blast-shield-kit.html Actually, this is the one I saw, which isn't nearly as hard on the wallet: https://www.wingtactical.com/firearm-parts/ar-15/muzzle-devices/vg6-cage-blast-diffuser-device-for-gamma-epsilon-muzzle-devices/ Quote Share this post Link to post Share on other sites

I have one on my 14.5..can't recall the model..i know no help...ill try to recall...what i do know...is that one i did get was undersized and would not make the plus 16.. The lil bit of weight you think you might have is very negligle.... stick with steel..imo Quote Share this post Link to post Share on other sites
Krdshrk 3,872 Posted July 28, 2020 My 14.5" Midlength has a Spikes Dynacomp pinned on. It's spec'd so that it will meet the 16" minimum when pinned on a 14.5" barrel. https://www.primaryarms.com/spikes-tactical-dynacomp-extreme-compensator-1-2x28-sbv1017 There's also a KAK Flash Can that will meet the minimum too. https://www.primaryarms.com/kak-industry-slim-flash-can-1-2x28 Quote Share this post Link to post Share on other sites
fishnut 2,358 Posted July 28, 2020 Titanium can be welded to stainless steel using pure argon as a shielding gas. Titanium can be brazed to steel but its not easy. On my 14.5 I use the BCM comp Quote Share this post Link to post Share on other sites

USMC1341 36 Posted July 29, 2020 @Zeke & @fishnut Thanks guys, do you mind posting a link to the BCM and SureFires you used? @JT Custom Guns I've seen you referenced on here multiple times for quality gunsmithing. I may have a job for you soon! I have a barrel on order, just need to decide what to weld to the end and order that too. Quote Share this post Link to post Share on other sites

USMC1341 36 Posted July 31, 2020 Thanks guys. Does anyone know if the KVP standard linear comp is long enough to make a 14.5" barrel a legal 16"? Or if I go KVP do I need to go magnum 3.25" (the obvious "safe" answer). The standard KVP is 2 1/8". Doing the math and assuming .625" subtracted for the threading, that puts it right at 16". Pushing it pretty close it seems. https://www.kawvalleyprecision.com/KVP-Linear-Compensator-p/kvp-linear-blk.htm Just wondering if anyone's built a rifle with this one and measured.

RUTGERS95 889 Posted August 3, 2020 vg6 gamma 556ex will extend right to 16" F&N tactical makes a knock off that I've used at less than half the price on some cheap builds Quote Share this post Link to post Share on other sites
InFamous 311 Posted August 3, 2020 I have the VG6 Gamma on my build, it's an awesome break but it's loud as fuck. Quote Share this post Link to post Share on other sites
Grapeshot 301 Posted August 3, 2020 OK, stupid question. For something that's turned and milled on CNC, why are these so expensive? Quote Share this post Link to post Share on other sites

USMC1341 36 Posted August 14, 2020 I'm probably going with one of these. Apparently the 2.25" according to KVP is legit to take 14.5 to just over 16.1, but availability is scarce, so I might end up doing the 3.25 incher. I already have a rifle with a loud ass break, and was looking to do one that was a little less blasty. https://www.kawvalleyprecision.com/category-s/151.htm Quote Share this post Link to post Share on other sites
