Remember Firearm Safety

Everyone is a Range Safety Officer, if it seems unsafe call it for a cease fire!

  • Treat all firearm as if it were loaded.
  • Never point a firearm at anything you're not willing to destroy.
  • Keep your finger straight and off the trigger until ready to shoot.
  • Know your target and what lies beyond.

In addition:

  • Ensure the weapon is safe to fire, a gunsmith is cheaper than a hospital visit.
  • Only use the ammunition type stamped on the barrel or listed in the user manual.
  • Wear eye and ear protection.
  • Alcohol, legal and illegal drugs, and firearms are never a good combination. Do not mix!
  • Keep weapons out of the reach of children, criminals, and other prohibited persons - it is your responsibility to protect your firearms!

Gun safe recommendations

I'm looking for something that I can store my guns and ammo in. Sturdy and hopefully fireproof. Budget is around 1000-1500 CAD max.

I've been looking at a website called Canadian Shield safes but I can't find reviews on them.

Need ideas.

Just picked up this psa upper. 10.5” What are some good optics for a close quarters? This will not be made for long distance shooting, just close targets and quick plinking/home defense. Eotech, aimpoint? Holosun?

Dumb question time

Why does the gun community go nuts over DPMS Kitty Cat builds, but every other time a 7.5” 5.56 is brought into the mix it immediately finds itself on PlebianAR? For what it’s worth I am in the camp of 10” minimum, but I find the difference in reactions interesting.

Buffer Tube recs..

I'm marrying a 16" BCM upper and Wilson Combat lower and wish to know if I should get any kind of special buffer tube and spring, or if the run of the mill PSA kind will be sufficient. Is one buffer tube and spring noticeably better than another?

Gave in and bought an EOtech - question about mount

I originally wanted the exps3 thinking I would future proof for NV down the road, but it's so much dough to get into NV, I decided to save the money. I bought an XPS2-0 for my 11.5". It was an impulse buy and I'm wondering if I'm going to miss the riser/mount of the exps3-0, let alone, the fact it is QD. Should I raise this up at all? How tall is the mount of the EXPS?

I'm thinking that at some point I will want to add a magnifier, so I'm thinking ahead of height over bore.

Follow up question: If I buy irons, what will be the co-witness situation be?

Sig Tango MSR

What’s the consensus on those cheap SFP Sig Sauer LPVOs? Are they durable? Basically, are they cheap cuz everyone wants 1-8 FFP instead of 1-6 SFP, or are they cheap cuz they’re shit?

How to finish an AR15 80% lower on a CNC Mill

Earlier this year I released a video showing how to mill an 80% on the 5D tactical jig. But since then I've bought an old beater CNC. So I decided to show how to do it there as well. Way faster! Also you can press the button and go do other stuff while it chugs away at it. It's a two part video. The one you're probably most interested in is the second one that covers programming the machine, the milling, and then checking of tolerances to ensure compliance https://odysee.com/@NotaGunTuber:a/CNC-Milling-80percent-Lower:a

But there is also part 1 which is a prerequisite for that. Part 1 covers the design and milling of the holder jig needed to secure the lower in the mill https://odysee.com/@NotaGunTuber:a/lower-holder-jig:3

How well do handguard mounted iron sights hold zero?

I'm getting a pair of sights for my first rifle, looking specifically at Daniel Defense fixed front+rear. My handguard is an Aero R-one.

I've read that irons mounted to the handguard can't hold zero perfectly, which makes sense since it's not attatched to the barrel nor the receiver.

My only question then is: How well would the sight+handguard setup that I have hold zero? What kind of PoI shift should I expect? >1MOA @ 100m, etc.?

I understand that buying a red dot is probaly just the easier solution, but I'd prefer to start out on irons since there's not much that can go wrong with them.
