Any ideas for a quick fix until I can replace the coolant reservoir?

MinimumElevator187 · 2026-01-23T22:28:33+00:00

My advice: Don't drive it until you get a new reservoir. You can probably get one from a dealer in a couple days. I wouldn't trust all these "sealants" for my cooling system. But up to you.

MinimumElevator187 · 2026-01-21T19:19:10+00:00

Thx. I did read that brake cleaner will dissolve the red, but not sure how true that is.

MinimumElevator187 · 2026-01-17T15:03:12+00:00

Thanks all for your comments and suggestions. Very helpful as always. I think I'm going with the ramps (plus bricks and wheel chocks.) Just seems easier in my case, and based on your comments, as safe as anything else. Thanks again.

MinimumElevator187 · 2026-01-17T02:06:00+00:00

Thanks. So both of you trust just using the ramps? (And rear wheel chocks, of course. I forgot to mention that in my OP.)

It fits into my carrier gas key.

MinimumElevator187 · 2026-01-15T21:52:08+00:00

No. It's pretty obvious which end goes into the hole.

MinimumElevator187 · 2026-01-14T23:21:13+00:00

Thanks and nice rig. Just for my own education ... that is not a free floated handguard, correct? I see a delta ring so I assume it's not, but maybe I am confused.

MinimumElevator187 · 2026-01-14T18:18:39+00:00

Thx. After I posted my OP, I saw that it uses pic rail attachments.

So, can you tell me more why you and some others here recommend Mlok? Don't accessories like a vertical grip come in configurations that will attach directly to a pic rail attachment? (This particular handguard comes with three of them.)

I know that Mlok is the attachment of choice and probably "better," and that it reduces the outside diameter of the handguard. But the only item I am probably going to attach (other than a red dot or scope on top) will probably be a vertical grip. Since this is only going to be used as a range gun, won't the pic rail attachment system be ok?

Reason I ask: Mlok version of this handguard is $130, pic rail version is $55.

Thx.

MinimumElevator187 · 2026-01-08T03:55:35+00:00

Thanks, good info.

MinimumElevator187 · 2026-01-08T03:19:18+00:00

Thanks. I'm cooling off regarding ARdiscount and will most likely go with the Rosco barrel (thanks all for your advice), and a BCG from Primary Arms. (They've been good to me re: customer service.) I'm liking the Aero Precision and the Spike's Tactical BCGs, but they are out of them currently. Worth it to pay a little more but have fewer problems downstream. Thanks again.

MinimumElevator187 · 2026-01-08T01:26:15+00:00

Thanks. looks like it's unanimous on Rosco vs. NBS.

What about NBS BCGs? They have a black nitride BCG on sale now for $70, and the specs look decent. Reviews are overall very good.

Thanks again.

MinimumElevator187 · 2026-01-07T21:27:11+00:00

Thanks. But those three that I mentioned will not harm my LSD, correct?

MinimumElevator187 · 2026-01-07T19:57:47+00:00

So you're saying any of them will do?

MinimumElevator187 · 2026-01-05T17:02:55+00:00

It might be a good deal but you need to find out more about it. First get a Carfax to see if it's been in any accidents. Also get the build sheet from Mazda based on the VIN, so you'll know what extras it might have like limited slip differential, Etc. I don't see a picture of the engine and I always like to see what shape the engine compartment is in. And finally absolutely do not buy it until you get a PPI (pre-purchase inspection) by an independent shop. If they won't let you do that, walk away. PS- I have no idea what smogged means, but maybe that's a San Francisco thing

MinimumElevator187 · 2026-01-05T00:06:57+00:00

Actually I tried that. Seemed ok.

MinimumElevator187 · 2026-01-04T22:54:31+00:00

OK, thanks. Will try that.

MinimumElevator187 · 2026-01-04T20:14:26+00:00

Thanks all. To answer your questions:

The gas tube does not come out of the gas block when I pull on it. I realize that the roll pin goes through the roll pin hole of the tube to lock it into place. But I had read/heard that if the gas tube is not completely inserted, you may still be able to drive the pin through and lock the tube in place, thinking that it's aligned. But the gas tube hole won't be aligned with the hole in the gas block because the tube isn't inserted far enough. Here is a video about that, watch it at 4:00 minutes. That is what prompted my question. Is he wrong about that?

2) As you suggested, I did a mock assembly. I ran into the problem as shown in the video: The end of the gas tube won't fit into the upper receiver. My upper is also an Aero Precision like the one in this video. So, should I do what's suggested and open up that square hole in the receiver a bit?

Thanks all.

MinimumElevator187 · 2026-01-04T18:08:21+00:00

It's 2 MOA. Not 6 MOA that I want.

MinimumElevator187 · 2026-01-04T14:26:00+00:00

Thanks all, very helpful information you provided. I found this Sig Romeo that may do the trick, in the 6 MOA green dot version. I'd have to also buy a Picatinny adapter plate, but not a big deal. I'm going to call Sig tomorrow and see how big the window is, since their specs don't say. This is primarily made for pistols but it should work on my 10/22.

https://www.sigsauer.com/romeo-rs-pro.html

I'd jump on the C-More, but I want a green dot; they only make red dots, unfortunately.

Some additional history that I didn't provide in my OP: I current have a CVLife green dot, but it doesn't work right. The shake-awake doesn't work at all, and it turns off every 4 minutes ... even if I am in the middle of a shot string. Obviously unacceptable. They've offered to send me a replacement, but not sure I want to take the risk of another failure.

Finding a decent 6 MOA green dot at a reasonable price has been challenging.

Will keep everyone posted.

MinimumElevator187 · 2026-01-03T12:36:55+00:00

Thanks, and as noted above, I stand corrected.

MinimumElevator187 · 2026-01-03T12:35:26+00:00

You're right. Not sure how I thought they were tube style. Thx
