Funny you should mention that. The Aimpoint PRO is the one I've been keeping an eye on. Every now and then PSA puts them on sale for under $400. I'll probably pick one up the next time I see a good deal.

So my new rifle took a big wet crap on me over the weekend

Picked it up from the gunsmith on Saturday, after he pinned the barrel and did the upper build for me, and polished the feed ramps.

So I took it to the range on Sunday to test fire and zero the iron sights, before zeroing the red-dot.

Got the first round off and was very surprised the sights were almost spot-on zero.

Pulled the trigger a second time.. and... mis-fire...
Waited 30 seconds, tap, rack, and fired again.. right on target

Went to fire again.. and mis-fire.. WTF?

Well turns out it was not cycling, so after a little diagnosis I find out the gas system is completely blocked, and no gas was being return to recock the action

I spoke to the gunsmith, who says he test fired it before I picked it up.
After he test fired it, he normally removes one screw at a time on the gas block to add loctite. Then leaves it laying down on a bench to set.

I'm told that after he put the loctite on the day before I picked it up, someone moved it and the loctite had probably got into the gas system and set hard.

He was really good about wanting to fix it for me, saying he would meet me Sunday even though the store was closed, so he could fix it.
As he's going to Delaware for the week, but I had plans in the afternoon, so I couldn't get it fixed.

Sorry that happened...

It's not a big deal to unpin a gas block, but Rocksett (or other high temp loctite, which surely he used on the gas block) is a bugger to undo. Usually keeping the screws from falling out only requires just the smalled dab of Rocksett.

I'd be interested to hear how he fixes the problem. I hope it all goes well.

It's hard to tell, but my guess is the gas block got moved and is mis-aligned.

I find it hard to believe he used that much loctite that it blocked the hole or tube LOL

Yeh, I agree, but how could the gas block move if it's pinned? Also, no gunsmith that I know would use a set-screw gas block without dimpling the barrel so that at least the rear set screw is set into the dimple, with both the barrel pin and the set screw in the dimple keeping it from rotating. Usually the Rocksett is just a tiny dab...only enough to keep the set screws from backing out.

The barrels that I use, BCM and Centurion, all come from the factory dimpled for the rear set screw on a gas block. I would never rely on that, even with Rocksett, and I always have the gas block pinned (if I'm not using an FSB) in addition to the Rocksetted set screws.

I hope he didn't mis-drill the dimple (assuming he dimpled it) or pin the gas block off-axis. IOW, install the gas block with the gas hole and barrel port misaligned.

I had the compensator/muzzle-break pinned, not the gas block, so I didn't have to pay the ATF any money for having a SBR

Anyway I'm sure I'll get the gas problem fixed next week

That stinks, Darren. Hopefully it gets fixed soon.

Finally got my AR fixed (gas tube was blocked with loctite LOL) so new gas tube.

Also had the Rail replaced, as I like the Midwest Industries 12" better than the Yankee Hill 10" that I had on there.

Also replaced the vertical grip with the Magpul (AFG2) Angled foregrip.

Got hold of a couple of HK 30 round mags

58 pages later and you're still talking about guns?

Not possible, I must have missed the derailing somewhere. Well I guess I can just start a new one
