14.5 vs 16?

[def90]

Trying to decide what barrel length I should go with on my one and only AR build at the moment. I have heavier caliber rifles for impact and long distance. What distance does the 14.5 start losing effectiveness and accuracy? I am trying to build more of a lightweight tactical/defense/3 gun type rifle rather than a long distance MOA rifle.

I am also pondering a suppressor for this rifle.

Recommend going 16 inch as it will give you more flexibility for flash hiders, comps, and future suppressor mounts.

I thought it would be cool to have a 14.5". Pinned and welded YHM suppressor adapter in it. Then decided to put a Lantac Dragon on the rifle. So drilled it out and welded the comp on it. Then decided to change the forearm.

Long story short, I should've just put a 16" on the build. Totally not worth the hassle to have to keep the darn thing legal. Now, if you just do stuff to rifles and then leave it be, it would work for you. Apparently, I'm not that guy!

Oh, then I built another AR around the barrel, dedicating it to the YHM flash-hider/suppressor adapter. I have been looking a it again lately, though.....

How hard is that to do? I am in the same boat right now. Thinking of moving to a Surefire comp, but am not sure if I can do it.

If you're talking about pinning and welding, it's not bad. It's better than the multi-point welding of "at least 3/4 of the radius" or whatever. I drilled a hole sized for a short cut-off section of shirt hanger. Countersunk the "pin" a bit so I could drill slightly oversized the hole the pin went into, then had the area welded a bit. I don't weld, so I had it done by those who I depend on for skills I don't have. I do a lot of stuff, with a lot of skills, but a man's got to know his limitations. The cheap oxy/acetylene kit at the local lowes won't do the trick, trust me, don't even try it.
You know someone that welds, that's your guy. BTW, soldering, etc, is not legal for this. It has to be welded.

You could have saved yourself a ton of typing by simply saying "Call Bert at BPTactical".

Bert does the cleanest welds you'll ever see, it's quick, very cost effective, and a pleasant person to deal with. Or, you can franken-weld it.... I chose the former.

Don't they allow silver solder anymore?

I took what he said to mean you can only weld the pin in.

Everything I have found still says you can still use high temperature silver solder to attach the extension. Higher than 1100 degree F silver solder.

Thanks, I was also wondering how you got it off without killing the threads. I looked on youtube a bit but did not find anything good.
Looks like I should give BPTactical a call. Maybe its not worth the risk of me screwing it up.

SBR a 14.5" and you don't have to worry about pin and welding it... Or go 11.5"


Or get a can with a dedicated mount. That will make you think twice about switching flash hiders
