Silencerco Omega 36M Announced

In some industry news, Silencerco announced the Omega 36M yesterday. I am a SiCo guy, and own a bunch of their products, so this was of interest to me. I will say that I was slightly disappointed by the final product, at least in the sense that it was not quite what I expected it to be, but on the other hand, it appears to be a pretty worthy upgrade to the current Omega 300 that provides it much more versatility without much of a weight trade-off.

To explain my disappointment: it’s modular, but unlike the Switchback, you don’t have the option of using the front baffles as your entire can. Recall that the Switchback has a serialized rear end module to prevent you from splitting it and using it on two rifles. The serialized portion on the 36M is the rear tube; the front tube is essentially a Charlie endcap with baffles and a Charlie endcap interface on the front. This is cool, but prevents you from using the front module as a K-length suppressor. Modular is a bit overdone in the current market, but being able to go K-length, standard-length, and extra-length with the same can would have really been a selling point. Perhaps we’ll see a Switchback 36 in the future.

Sig Optics Whiskey5 1-5×24 Review

 

As part of my Sig 556 platform modernization project, I wanted to replace the old Nikon P-223 3x scope I had on my Sig 556 SBR with a more modern LPVO. I selected the Sig Optics Whiskey5 1-5x based on a careful analysis of my gun’s use and requirements. The review focuses not just on the optic itself, but how it fit those requirements.

Read on after the break!

Sig 556 Platform Modernization Project

On the recent Primary & Secondary modcast 187, Matt was discussing his new DSA FAL and the general concept of taking what was an obsolete battle rifle and making it new again. I thought this was a cool idea, and decided to embark on a similar project. I have a number of relatively obsolete guns in my safe, but a fair number of them are in “mil-spec” configuration, and thus I don’t want to alter them. But I do have a Sig 556 SBR and a Sig 556R Gen2 that are basically just old “cool guy” guns from a decade ago, and thus fair game.

I took a long look at them, and what I thought needed to be improved… and did it.

Green Ops Defensive Carbine I Clinic AAR (Sig Optics Edition)

IMG_20190428_211354.jpg

My second Green Ops class of the year was another run of the defense carbine I clinic on April 28, 2019. This is probably the fourth or fifth time I’ve taken this class, and every time, I get something new out of it. It’s also interesting to see how Green Ops has been evolving as a company, and how the classes change due to feedback.

Besides my usual goal of improving my somewhat dismal carbine skills, I had two secondary objectives:

  1. Test out my Sig Optics Romeo4M and Juliet4 combo under harder-use conditions.
  2. Get some runs on my AMG Lab Commander shot timer in prep for an upcoming review.

IWI Carmel Rifle @ TFB

TheFirearmBlog has an excellent article on the IWI Carmel rifle that was displayed at the LAAD expo in Rio recently.

It looks a lot like what you’d get if you crossed a Tavor with a Galil ACE, and it does look a whole lot like the ARX-100. Height over bore is a little bigger than I’d prefer, and it doesn’t seem to have ambi-ejection, but it appears to be a solid traditional-format carbine. I think it’ll sell well in the US if they can bring it in under $1000.

I’d hazard a guess it’s for export purposes, albeit I do think the IDF would do well to have a non-bullpup rifle available for cheap domestic manufacture in the event that they want to transition off the M16 for political purposes.

I need someone to explain .300 AAC to me; or, better calibers for your AR

Every time I see someone ask about non-5.56 calibers on the AR-15 platform, there’s a legion of fanboys who start proclaiming that .300 AAC (aka, .300 BLK or Blackout or whatever) is the way to go. Let’s take a look at its capabilities:

  • Subsonic .300AAC? All the ballistics and energy of .45ACP. Somewhat better penetration due to bullet profile, but I don’t get the hype at all. We’ve spent literally decades declaring PCCs and SMGs dead, and now this is the hotness?
  • Supersonic .300AAC? Nearly indistinguishable from 7.62×39 in terms of ballistics, and if you’re OK with .308 bullets in a .311 bore, the bullet selection is the same.

Yes, .300AAC can be a .45 ACP and a 7.62×39 on demand. That’s the best cartridge design of the years 1911 and 1944, all in one gun. That’s not a compelling to me. But, OK… let’s say that is compelling to you. I can use my imagination!

Green Ops Defensive Carbine I Clinic AAR (IDF Colt Commando Edition)

IMG_20190106_192328.jpg

Continuing my tradition of running my guns hard and Israeli-style, I was very happy to kick off the new year with the Green Ops Defensive Carbine I Clinic this past Sunday. This was the third time I’ve taken this particular class, and I can say that each and every time, I’ve learned something new.

This time around, I decided to go with my IDF Colt Commando carbine clone. Yes, that’s right… I went with a plain-old AR-15 for once. Read on for my impressions of the class!
