I was watching an AK build video and a question came to me. Since an AK (and I'm sure many other firearms) can be fired without having a stock attached, must you build them from kits (or in the factory) in such an order that you do not accidentally create a SBR, or is their some legal grace given to firearms considered to be in assembly. I am not American so apologies if this is obvious to those more familiar with your laws.
Had my Glock 17 for a while and since I already have some other duty built pistols, I decided to make a little race-gun style build out of it. Had some issues at first:
Long story: after putting on the 5port comp and the new slide I was having short stroke/FTE issues, assumed to be from the comp soaking up all the energy. The man himself told me I needed a reduced power Striker spring and a 10lb round wire recoil spring (ah, duh) and that I needed 145+PF ammo. but after installing I was still having issues with FTE/FTF so I took it to a gunsmith I knew and he casually takes the little fin holster clip off (i didn’t mention this was on here earlier bc I didnt think it was an issue.) puts in an 11lb flat wire recoil spring, and lubes up some affected areas. (Im in the background like theres no fucking way this is going to do anything.) Bang Bang Bang…. You gotta be joking. It works.
Short story: Im a dumbass and didn’t realize that because the comp was so massive and the recoil spring was so light, the squeezing of the holster fin on my frame was slowing down the cycling of the slide just enough to screw everything up. Also i was shooting a PF of like 138 so that didnt help.
Holster fin is off, PF ammo 148, shes running good!

I just finished my single shot target pistol about a month ago. Yeah, it’s ugly, but I built it from the ground up and I’m proud of it. I manufactured everything from raw stock with the exception of the springs. Barrel machined from 4140 steel. It was drilled, reamed, rifles and chambered on my lathe. Frame is 3D printed from PETG. Bolt body, firing pin, sear and locking pins are all machined from 4140 steel. The rest was made from 1018 mild steel.
Considering this was my first homemade barrel (and first homemade gun, in general), it came out exceptionally well and is very accurate. The picture doesn’t show it, but I’ve attached a picatinny rail to the top of the receiver and put a red dot on it. It’s currently one of my favorite guns to shoot. I’ve put approximately 1500 rounds through it so far. I have a list of improvements I want to eventually make to it, but for now it works.
UPDATE:
Since some of you have asked for pictures of the internal components: https://imgur.com/a/jTyaGkb
I’ve numbers the components. Feel free to ask questions.
