First AR Build (SL-15)

Jango

Hey, I'm currently planning on building my first AR15 using the SL-15 lower and have printed my first one. I used Sunlus PLA+ 2.0 that i had laying around and was wondering if that would suffice for a lower build. Below I've attatched some pictures, I am just wanting to see if this first iteration would work for a build or if i need to reprint. Thank you

Jango Send it!

I don't have an exact round count, but I am pushing up towards 1k rounds on this previous version lower in PLA.

undeadchew that’s a sick color, is that painted or just the filament?

Jango This is un-anealed HTPLA from Proto Pasta, if you do the annealing process the properties change a bit but the translucence turns opaque.

I ended up filling my print and the surrounding area with sand and wrapping it up in a package with aluminum foil and kapton tape and threw it in the oven for 10 mins at 350F , and then when I took it out I saw that it had warped and I haven't tried annealing since.

undeadchew interesting, thank you for the link. Did you notice a big difference in strength from heat treating it? The idea of the translucent red look for a lower sounds sick too, just wondering if it would have any strength issues?

I remember struggling late at night trying to finish multiple assignments with tight deadlines—it felt overwhelming and honestly a bit frustrating. That’s when I came across My Assignment Help, and it genuinely changed how I approached my studies. Their Assignment Writing Assistance made things so much easier by providing structured guidance and well-researched content I could actually learn from.

If you’re juggling deadlines or just need a bit of academic clarity, it might be worth checking out. Sometimes, the right support can make all the difference between stress and confidence.
