Building Confidence

Sorry I didn’t see this earlier. I was going to suggest some oil as that would not hurt the finish but, glad you were able to get it out and the new one installed. Congratulations. To be honest, I have never installed a delta ring, all mine have free float hand guards. Let us know how that goes.

Day 3 of installation complete. Delta ring and gas tube installed and aligned. I took advantage of a trick I learned on a Youtube video to re-align the delta ring etc. I should have purchased an "assist" tube to keep the item aligned, but I got them aligned and the gas tube free flowing, somehow.


I attempted to install the gas block. However, I must need to learn some things about installing roll pins.The roll pin atop the gas block that locks the tube in place doesn't fit. Too big. If I attempt to force it with a roll pin punch, it will splay out the roll pin and the punch falls through it. I checked the fit manually with the tube outside the gas block. It just doesn't fit. Taking a very small roll pin punch, I can get it through both the block holes and the gas tube holes. But way too small to hold it tight, obviously. But at least it keeps it aligned while I look at a different solution. Also, I think I'm going to have to go with the triangular HG cap because I can't get the HG on with that cap. Either that, or I may have to adjust the gas block position by a microscopic amt. (I can't move it that much or it won't align with the barrel's gas port.



I guess I'll be spending a bit of time looking for spare roll pins that fit the block as well as other roll pins.



But a little bit of progress today. I think I'll take some time off the build and play with my new RIA 1911.

Something is up with that pin, don’t force it as you know. It should be tight but not that tight that it deforms as you punch it in place. Good idea on buying some spares. Sometimes it’s good to revert your attention to something else so you won’t rush your build.

What’s the plan for the 1911?

Finding a site where I can test fire it for a bit. Not too much because I have to preserve my .45acp ammo. Then it will be a back up gun while my P320 remains my EDC.



I see where to by spare roll pins on Brownell's, so I'll do that as well and get back to the build. But I may practice a few roll pin pushes where possible.

A cheap digital micrometer is your friend..then you can mic pins and see the variations in what pins you have

Excellent, ! I will get one. I hope I can also measure the holes the pins are supposed to fit in so I can gauge what size pins I need.

Thanks!

Normal micrometers only measure outside diameter, not inside like calipers can. Inside micrometers are for large holes (>1")

To measure a small hole, you'll need a small hole gauge, which you expand until it fits the hole, and then measure it with the micrometer.

Update: I'm going to have to do some re-thinking. I may have to change both the hand guard and/or the gas block. Things are just not fitting properly.


The HG itself is having trouble fitting into the delta ring. I did not have this issue before when I used the Colt LE6920 OEM1. It fit perfectly. Furthermore, I think it's too long, even for the 16.1 " barrel. I'm trying to fit it on and it just isn't fitting into place. We'll see. I took the roll pin from the other gas block that didn't have the set screws and tried it. While it does fit through the block, it doesn't line up with the tube holes.


Earlier, C aleb said (in re: HG and Gas block):

That won’t work. That handguard is for the m4 style barrel but and “A” front sight. Stand by while I search for links on what barrel but you will need for that hand guard.

Here is the barrel nut and delta ring you need.

I am wondering now if we could in fact, use a different low profile gas block that could fit underneath the HG front and would allow the HG to seat properly. I'd still have to worry about it fitting on the delta ring but I'll work on that. If it won't, then I may need your guidance on selecting a "free floating" HG because this MOE HG is just not working properly for this build. I'll still stick with it but at some point I'm going ot have to consider some other options.


Anyway, my spare roll pins should arrive in a week or so.

Silly question but, is the HG an actual OEM Magpul and not a copy made for airsoft? The copies are really close to the look but the tolerances and dimensions are sometime off a little.

Well, put it this way... it comes in a regular MAGPUL MOE box with all the appropriate markings, etc. I believe it's an actual OEM. There are no Airsoft markings anywhere or any other indications therein.


From what I can see/tell, the barrel nut may be a bit larger in diameter for the HG around which to fit. Do std. Milspec barrel nuts come in different sizes. Are some of them "Proprietary" in size? I"ll call Magpul tomorrow and get an answer to that. I might have to change out the barrel nut and delta ring. That's at one end. Then I have to worry about the other end near the gas block. The triangular HG cap does fit. But I don't know if I can get it snug with the back end. We'll see.



Let me see what Magpul has to say about the barrel nut and then we'll plan the next moves.
