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!

Eotech vs. Vortex Huey vs. Sig Romeo 4t, which one and why?

Looking into optics, generally narrowed it down to those three units.

General purpose optic use, mainly plinking and training and learning, going on a 13.7” Jakl, most likely adding a magnifier eventually.

No need for NV compatability. Not real worried about battery life. Would like absolute or 1/3 cowitness options. No plans for risers. I’d like fde but can also paint it up.

Vortex Huey Eotech, probably an EXPS2 or XPS2 Sig Romeo 4T (only non holo of these 3)

What’s your pick out of those three? I’d consider a T2 but they are $$$. Most likely starting with something used, that’s most likely the plan outside of the Vortex which I can get a good deal on.

They’re all good optics, much of it will come down to personal preference. I’ve seen the specs and common talking points of each, just want to hear from real world folks directly using them instead of their marketing schtick.

What would you all pick out of these three options?

Thanks!

Upgrade from Sig Romeo 5?

My COVID battle pistol has served me well, and the Sig Romeo 5 has been a great little dot for my first build but I’m getting a small amount parallax and I’m ready for an upgrade.

I have a Juliet 4 magnifier, and wanted to get a new dot that will work with it.

Looking at the Aimpoint PRO. Any thoughts on combining it with the Juliet?

Where to check what states are AR pistols legal

I tried googling but still unclear. From what I can tell CA is the only state where AR pistols are illegal because CA has a designated handgun/pistol roster and ARs aren’t on that roster. I move around a lot for my job so I just want to make sure I’m all good before building an AR pistol.

7.5" buck hunting build

Going for size compaction and weight reduction with this build. The net is a brass catcher as I don't like to litter. Buffer tube is not comfortable to shoot but it fits snugly is my hiking bag and I usually only take one shot.

Initially was shooting a cheaper .223 XP round that didn't like to expand consistently under 10yds. Haven't had any issues with these so far.

I'll usually bag one on a night hike and move it off-trail. By day time I'll bring some binoculars and/or a magnifying lense and it's as if I have created my own personal nature documentary. I'll see all sorts of rare animals visit the scene. It's very interesting. I see it as a gift to the decomposers of surrounding the ecosystem.

Be mindful of what what's beyond your target and happy 'hunting' to you all!

Light setup for key mod suggestions?

Not a huge fan of keymod but that’s what came on the rifle. I’m Wanting to do a surefire scout light setup but out the box they only have Mlok and picatinny mounting options. I’m leaning towards just buying a new handguard since I’m not too fond of keymod anyways.

Hand guard Help

I really wanted this hand guard for a build I’m doing but it says it is only compatible with triangle hand guard caps but I have the round .750 on my AR. Are the hand guard caps relatively cheap/easy to install?

Cloud defense Rein 3 issues

Seems that the tailcap is always somehow coming loose and not allowing the flashlight to turn on 100 percent. Anyone have any of these issues?

Next build?

I’m looking into a another build. I currently have a 10.3 300blk Home Defense and a 16” “SHTF” build that’s running a lpvo with an offset dot. I have some parts laying around but unsure on next barrel length. I’m stuck between 12.5 with RD and magnifier or an 18” Dmr build. Both options would be suppressed and would be 5.56. Appreciate all input!

Pmag 30 failure to feed

I have problem with two of my pmags. They got quite dirty and started to cause malfunctions - failure to feed on last 1 or 2 rounds. I cleaned them thoroughly, but problem still occurs. When I push follower of empty magazine in with my finger it often "hangs" in specific point as if there was something blocking it. I don't see anything inside magazine shell which could cause that.

Did anyone experienced similar issue?

Balistic advantage 14.5” midlength

Does anyone have experience with this barrel and specifically how was your gassing? I had got this barrel on trade and all the other components to build my upper. I was leaving town for work so dropped it off to a gun smith and figured it would be ready when I got home. Gunsmith said it didn’t properly “cycle” when they function tested it and felt the need to drill out my gas port to 3/32”. They told me this was a common issue with ballistic advantage…I call bs and now my brass ejects completely forward.

PWS MK116 Mod 1 vs Mod 2

I’m ready to purchase my first AR and am going to buy a Primary Weapons Systems MK 116, but there is a Mod 1 and Mod 2 both available relatively close to the same in price. Does anyone know the difference between the Mod 1 and Mod 2?

I went to the PWS website and couldn’t determine exactly what the difference is. I know new isn’t always better, and I’m okay to purchase a gun with more basics if that would be better as a first time user for the AR. I will familiarize myself with the gun very well and will shoot regularly, but at this time I probably won’t consider changing anything out (upper, lower, barrel, etc.) and will keep the gun as factory with addition of scope, light, etc.

Ultimate lightweight suppressed recce build

What’s the ultimate, light weight suppressed recce build? (In a wooded out Garand thumb world, Is recce still a thing?) I’m talking a light weight rifle that you can hike all day with, engage targets 0-500yds, and trust in a duty role, all without spending Knights money.

This is my idea so far:

CAT WB suppressor (Ti for weight or inconel for less sparking) Rearden R2S flash hider Geissele CHF 13.9 barrel mid length Q adjustable gas block BCM 13in mcmr hand guard BCM mk2 upper Geissele Reliability Enhanced BCG Primary Arms PLX-C 1-8x SFP w/rmr BCM recoil mitigation buffer assembly Stock of choice Lower of choice (I like radian model 1) Geissele SD-E trigger Magpul K2+ grip

I’m thinking the Geissele URGI/Superduty rail is overkill and too heavy. Could ditch the adjustable gas block for a super duty and adjustable bootleg BCG.

The Q Sugar weasel 5.56 13in SBR is probably the closest to this build off the shelf.

What would be your build for this role?

Zero Distance For Irons On A Carbine

I have an 11.5” carbine (5.56) and i’m deciding wether to sight my irons at 25yds or 50yds.

These are backup irons, I have a dot optic zeroed at 100.

What do y’all think?

Asr mount for banish suppressor??

I got a email that silencer central is waving the tax stamp for all ONX elite members when you buy a Banish suppressor. I'm wondering if you can put it on a asr mount or if someone makes one that will fit it? I can't tell if you can remove the direct thread mount or not.
