Retro Commando pistol (UPDATE)

[imarangemaster]

You could get a 14.5 inch pencil barrel, get a Bushmaster "slip over flash hider, which I believe has about 1.5 inch in front of the threaded portion, and pin it on. I had a 16 inch with a slip over, and it was too long. 16 inch gives you about 3100-3150 fps with 55 grain, but the 14.5 ives you 2900 fps and 11.5 gives you about 2750. It takes 2550 to 2600 fps for the USGI M193 to fragment and tumble effectively. That is why i went with the 16 inch M4 barrel on my carbine build.

Here is a build I did for my son about 4 yeras ago, though he later went with a birdcage FH.

That's a nice little lightweight package there.

I prefer a more standard carbine now too, M4gery...

Update 4 May, 2014:

Okay fellas, I bought a new YHM bolt and took it out this morning to run it through it's paced. It passed with flying colors! This little weapon is so danged awesome! I really do love it! It ran two 30 round Colt magazines without a lick of trouble.

Were we talking about this bolt problem before? Are you going to rebuild that bolt too? Shouldn't be too big a problem.

Jim, the bolt components were discussed but not specifically the bolt. I will pick up one of those bolt refresh kits with ejector, ejector spring, extractor, extractor spring, extractor plunger and gas rings and go through it. I'll have a good spare then. I suspect the ejector spring in the culprit even though it measures the right length. I'm just happy it is up and running good.
