Discovery Optics Precision Height Adjustable Scope Rings

Scope rings that allow you to adjust their height above the rifle base are nothing new. These rings allow users to mount a scope with a large bell on a variety of rifles without having to change the rings to accommodate different clearances. But many suffer from design flaws that cause them to shift and lose zero over time.

Discovery Optics has brought its high-quality design and construction to adjustable rings. Their 30mm rings are made of aircraft-grade 6061 aluminium, which come pre-lapped. Furthermore, the adapter shims that allow the mounting of 1″ tubes (25.4mm) are made of aluminum, not plastic. Both the rings and shims are pre-lapped to create a smooth surface and provide the maximum contact footprint with a scope tube.

The rings feature locking teeth that prevent the rings from dropping and two locking screws that make it impossible for the rings to shift from their locking position. Each ring feature 6 locking Torx screws and are thoughtfully printed with the mounting sequence and inch-pounds of screw pressure to apply to each set of screws,

Stretching It Challenge – CCI Standard

YouTuber @dayattherange posted the Stretching It challenge on his channel. Elijah has invited his viewers to download his target and see how well they can group 22LR from a distance of 100 yards. https://dayattherange.com/stretching-it-2025-year-long-challenge/

For this attempt, I chose to use plain vanilla CCI Standard Velocity, an everyday bulk/practice ammo that shoots well in my rifles.

CONTEST: ZKT Gun Wipe Giveaway

I’ll be giving away free samples of ZKT Gun Wipes to lucky fans who join the chat on my weekly livestream show, TMI Live, Wednesdays at 6pm EST / 3pm PST. During each episode during the month of June, 2025 I’ll be sharing clues to a live quiz contest. Type the correct answer in the chat and you’ll be automatically entered. I’ll select 3 random winners from the correct answers at the end of the show.

ZKT Gun Wipes

ZKT makes a variety of firearms gear and supplies, best known for making deluxe armored firearms display cases and gun safes. This year they came out with individual gun cleaning wet wipes. These single-use packets contain a cloth wipe impregnated with proprietary cleaning, lubricating, and protectant solvents.

I cleaned a dirty bolt carrier group (BCG) with a single wipe. I didn’t have to use any brushes or additional CLP. All I used was a single half-sheet of paper towel to dry it off and catch any leftover fowling and was surprised at how little was left. The wipe’s fibers really did a great job capturing the dirt, dust, and carbon.

I gave it a final wipe-down to leave a light coat of lube on the metal. When I picked up the BCG a few minutes later to put it back into my rifle, I discovered it was completely dry but I could feel a light dry coat had been left on the metal.

I set to test the rifle at the range and along the way, I got a message from the marketing director of ZKT. By sheer coincidence, he was in San Francisco to attend a 3-gun match. I met up with him in person at my local range and got had a chat with him about this new product. He told me he could clean a complete rifle with just one wipe.

He also supplied me with extra sample packs of the wipes. I’m going to give them away to folks who join the chat during my TMI Livestream show on Wednesdays 6pm EST / 3pm PST during the month of June.

Tactical Snacks Gummies

I saw a lot of cool tactical products at SHOT Show 2025, but one of the most surprising new products was a packet of fruit gummy snacks. Tactical Snacks is a veteran-owned company handing out sample packs of their Watermelon Overwatch gummies.

Tactical Snacks were created to provide low-sugar alternatives to regular gummy candies. They come in two varieties: Sour gummy with 3g of net carbs and High Protein with 9g of net carbs and 8mg of protein per packet. Their ingredients have a welcome lack of high-fructose corn syrup.

The taste of the Sour Gummy variant is very similar to Sour Patch Kids candies. The High Protein variant has a harder and chewier mouth feel and a sharp, slightly bitter aftertaste. It reminds me of chewing on vitamin-C tablets. The Sour Gummy is my favorite of the two, but both would be satisfactory on a hike or patrol.

Brand Clue:
This 3-letter name company’s full name was America Online, and the ubiquity of their promotional floppy discs and later CDs, became a cultural touchstone. Despite dominating the market in 2001, its business shrank with the decline of dial-up internet. By 2015 it would be bought by Verizon.

SHOT 2025 Swampfox Optics

Swampfox is a rising US optics brand that has made a name for producing value priced red dots. They’ve expanded into LPVOs and long range scopes. They’re following the template of Primary Arms by offering premium design features for a value tier price just a bit above budget.

I’ve never tried out their optics but many of my viewers have suggested I do. I stopped by their booth at SHOT Show 2025 to get acquainted with their red dots and LPVOs. Their red dots feature a selectable multi-reticle and their LPVOs have well designed reticles more in line with my tastes. I hope I can get an opportunity to test one later this year.

SHOT 2025 Aguila 556 Battle Bag

At the Aguila booth in SHOT Show 2025, they showed off such a no-brainer innovation. Their 5.56mm ammo will now also come in 30-round boxes. Considering 30-round magazines have been the military standard for the M16 platform for over a quarter century, it’s about time. Prior to this, 5.56 (and 223) ammo was normally sold in 20-round boxes. Moreover, Aguila is offering these boxes in 450-round sealed polymer Battle Bags with built-in handles for fast and environmentally protected handling and transport.
