I finally did some shooting with the new gas system installed.

I began with Radway SS109. I started at setting 3, which was throwing brass 15 or more feet away.

Setting 2 was still throwing stuff well past 10 feet, so I moved to setting 1, which was just right. Talk about smooth operation!

I then switched to Wolf 62 gr hp, fully expecting to see malfunctions. I ran through an entire magazine with no problems at all on setting 1! This new piston and gas-block are obviously more efficient than the old setup. Setting 1 with the old system would give me consistent double feeds with Radway and Wolf worked most reliably with 3.

I was going to switch to "S" to see if it would work, but the block was hot, I was short on time, and I had to function test an AR I had been having trouble with.

As a side note, the AR I was working on was a "standard" 16" carbine. After shooting the XCR on settings 2 and 1, the AR felt almost excessive in the recoil department (not like they really are) and it's very obvious how much smoother the XCR operates.

I found the same thing, I can shoot on 1 or 2 with most any ammo with the new system. I shot an AR for the first time in a long time this weekend and kept getting distracted by that dang ping...

If you don't have the new gas block you are missing out.

I need to get around to this. I'll need the new piston head for the x39 conversion anyway.

Damn a lightning bolt just hit me! The first time I shot my XCR I was suprised about the amount of recoil that it gave. Much more than I expected. However, this was during the break in period and I shot about 50 rounds to finalize the break in. The block was too hot to dial down so I never got the opporunity to dial it down!

:duh:

Same here, with the original gas block setting 4 was necessary with the surplus ammo I was using. With the new gas block, setting 2 still throws the brass over 10 feet.

My other rifle is a 300 Weatherby, XCR - what recoil?

 

[thadbme]

Hey last time I shot was with a pistol so it wasn't tucked in my shoulder! Turkey season is on now... I'll find out what recoil is like with some of those 12 gauge 3" magnums!

It would be nice to be able to change the gas setting when it's hot. I don't know if it's possible, but if the detent could be modified to provide resistance, not total arrest of movement, it would be great.

 

[aziator]

I change mine when it is hot, just have to be quick so as to not burn your fingers.

 

[gr8santini]

Lick your fingers first, then be fast!

 

[crashy]

Couldn't you use spent casings or some other inanimate object to change the gas setting while hot? I thought that's why there's a hole through rotating plug.

I'm sure that would work, but it's not at tactical as spitting on your fingers.

Yes, I was just too lazy to pick one up.

Or wear gloves when you shoot

ninja gloves? ;D
