This is NOT to check the diameter of your barrel or anything else! Just to check if there is a bulge in your barrel.
Glocks method of checking the barrel is to remove the slide and push it the barrel hole and make sure it does not have a bulge. I wanted something I could use on barrels that are not installed without having to remove a slide.
This example is for 9mm Barrels. I measured several 9mm barrels and slides for Glocks and came up with 0.580 inch for the inner diameter. Because printers vary check before you use.

Just slide it over your barrel and check for a bulge. PLA is softer than the barrel so there should be no marring.

My Present Arms Gunners Mount Kit is awesome. The one thing I wanted different was the Receiver Alignment Block. It does not seem to fit right on non-mil spec buffer tubes I work on. How can they know all the sizes?
You can see the gap here, it will not seat all the way.

And that is because the buffer tube rail is too wide.

A sleeve to help hold your castle nut wrench firmly in place while cranking it down on your Present Arms Gunners Mount.
I can not claim this idea as my own, I was watching this video from School of the American Rifle and though “What a great idea”. I did not have any 1 ¼ inch PVC laying around, but I do have a 3D printer and PLA. This is what I came up with for the below wrenches.

AR Compensator (Flash hider) No Torque, timing value with the procedure in the Army TM. Hand tight and then tighten a minimum of 90 degrees but no more than 450 degrees to timing. Don’t over tighten, don’t loosen.
AR Barrel Nut 30 Ft. lbs. Minimum, not to exceed 80 Ft. Lbs. to align the next slot in the barrel nut. The 80 Ft. Lbs is not stated in the TM, but I don’t know how you would line up the gas tube, without going over 30 Ft. Lbs. Unless you use shims. I don’t think most folks will have any laying around. This torque spec is common across the community and internet.
AR Carrier Key Screws 50-58 INCH pounds torque
AR Lower Receiver Extension (Buffer Tube/Castle Nut) 40 Ft. lbs for both Rifle and Carbine.
M-LOK Accessories:
For attaching metal accessories to metal hand guards: 35 in/lbs
For attaching polymer or metal accessories to polymer hand guards: 15 in/lbs
For attaching polymer accessories to metal hand guards: 15 in/lbs
The installation torque values are not minimums, they are recommended limits. The nylon patch compound may slightly affect the torque reading if using an in/lb torque wrench.
Using a small hex wrench should prevent over-tightening. Remember that the recoil lugs are doing most of the work, and excessive torque on the nuts is not required
My Comments:
The rest of the items in the research below I could not find in the Army TM, manufacture website or in common reference. Until I can find it, I am going with ‘tight’ and the appropriate thread lockers. ‘Tight’ might be the values listed.
I am not saying that the info below is wrong or bad. I could not readily verify it. The above is what I will use, at the end of the day I am responsible for my decisions and you are responsible for yours.

Not all feed ramps need to be polished. If you fire quality ammo with good quality barrel and upper, you might be good. If you reload and like to try different projectiles, cast your own or you are having feed issues, good idea to polish them up.
When I polish feed ramps I do it with the barrel removed from the upper. I am not going to risk screwing something up on the upper. It is more work to remove the barrel but worth the effort for a better finished product.

I wanted a tool to help get the magazine catch pushed out of my M16/AR-15 without scratching or marring the metal. To compresses the spring and make removal of the magazine catch easier.
Looking around I saw AR Magazine Catch tools similar to mine on various web sites for around $10 without shipping. I am frugal and own a 3D printer, I decided to make one.
I know you can use many other things to push it out, such as, but not limited to, pencil, punch, your kids finger….If you have a 3D printer it is a quick and cheap print.

I recently took the Glock Armors course. It was fun, got to hang out with some like minded individuals and have some good conversation. Both the Instructor and the Sales guy stated several times that Glock is very Military and Law Enforcement oriented and that those groups are around 80% of Glocks business. Any input from anyone but those 2 groups will fall on mostly deaf ears.
If you don’t pass, it is because you don’t want to. That said, I am still out if the “Certification” holds any real value other than a civilian / business being committed enough to spend $250 on some swag. Maybe parts straight from Glock? There is no certification number to identify you, no logo for your business from Glock I could find, no website for customers to verify you are currently certified.
The Law Enforcement customers don’t individually pay for the class or get reimbursed. The LE guys I talked to need continuing education points and like to shoot. The free class is a win-win for them.
In the class I took, the benefits of Certification were never touched on. No idea from the class how to order parts or who to contact if I need something. No “front of the line” if I need help. Law enforcement get a hold of your sales guy. You will get a gray scale certificate in the mail 4-6 week after the class.
I don’t know if I will spend my own money to get re-certified. I just cant think of a benefit for myself. I could buy a lot of Glock factory parts from a reseller for the money I spent, maybe even a new Glock with the GSSF Pistol Purchase Coupon or a good part of it. Ammo and Training….
Class $250
Gas at least $50
Lodging / Meals $100
I do not consider GSSF membership to be part of the value of the Certification. 2 Separate things.
Don’t get me wrong, I will shoot my Glocks until they fall apart. I just don’t see what the certification gives me, what the value is. Over $400 is a lot for lunch, socializing, and a piece of paper no one will ask for.
1-24-23: I have been ordering a lot of parts. I am starting to see a return on my investment. I will keep updating.

I have a log book for each of my pistols. I track what is installed, magazines, rounds fired per barrel and total. I also track, reload data and maintenance. I wanted to post it here to see if anyone has improvement ideas.
