Seekins Precision has sent me a new gas block, with a bunch of swag for my time (a patch and some decals). No return label hrm. They have quite the catalog too.

Primary Arms CS just amazes me. I called in about my problems with their scope on Tuesday. I have a replacement 3 days later in my hands. Kudos. These guys are on the ball. I opted for an upgrade, and got a Viper PST. WOW what a difference in build quality and brightness. I'm almost afraid to take a look at the HD Razor series. How much better can glass get? I'll find out soon enough. I've been eyeing their razor HD (high density, no high definition heh) for a long range upper thats I've been planning. This thing is amazing. Can't wait to take it for a spin.

I know right! Seems to me, the more you know, the more you spend.

Mounted the PST last nite, took a while to do it, getting the eye relief just right. Probably remounted it 8 times last nite, then figured out the relief changes as you magnify it, and had to remount it again >.< mental note, mount it on the highest mag setting.

I'm glad I got the PST, its smaller, a little lighter, and the glass is a whole lot better. Its pretty amazing. I can't wait to go sight it in.

Also added a Harris bipod on a QD last nite, and spent the night popping zombie heads watching Walking Dead Reruns. Oh What Fun!

I have a request for anyone with a spare moment, or is working on their rifle right now.


I took off my handguards last nite, and moved the gas block and measured the width of the barrel by the gas port. I measured 0.736". It seems to me its off by 0.14" should be 0.750" Can anyone else give me a measurement by their med contour gas block?

TIA.

Sorry AT, I didn't open this thread until now.

My PSA gov't profile barrel averages 0.751" between the pinned legs of the of the FSB. My calipers gave readings of .750, .751, .751 and .753".

Ah, glad someone else replied, thanks Khromo!

The PSA barrel is 0.676" in front of the raised area at the gas block. It's not really a gov't profile since it doesn't get to .750 except at the block, PSA calls it a lighter profile barrel. It's 0.625" under the handguards like a pencil but uses a standard gas block and doesn't drop back to .625 in front of the block.
