I tried 180 gr Speer jacketed soft points thinking that I could reduce the copper chunks coming through the gas port into the bolt vs. the plated bullets. Fouling in the bolt is less but I ended up with chunks of the jacket in the suppressor. Do I just have crappy bullets or is the short barrel/gas ...

In an effort to try to cut out recoil I took the jp silent captured spring, cut the spring down by about 4”, removed the buffer and cut a new one out of acetal. Also got a lightened bolt. I will start with no gas and work my up to get it to cycle. We’ll see if it works.... http://i65.tinypic.com/2n...

Here is a pic of the blank on the upper for the mini piston project.

Midway is doing a close out, buy the 180’s while you can

What is total length and length of suppressor?

4.4” bbl + 8” can = 12.4”

I was wondering about overall length of the whole pistol. Probably should have included collapsed and extended for to make better sense.

29.25” extended, 26.5 collapsed”

Using a boring head to cut barrel pass through on micro piston block.

Fixed the bolt that was tight. It was the gas tube the needed to be bent slightly up. Got the short gas piston gas block roughed out and squared.
