The Maxim Defense CQB Stock: Short and Sweet

The Maxim Defense CQB Stock is a strong, comfortable, durable and compact stock that is made for real-world use. The Maxim CQB Stock weighs in at just 18.59 oz and has a housing made of 7075 Aluminum Alloy where they’ve smartly placed QD mounts. When closed, the stock measures just 5.375″ and extends out to a full 10″, the same as a extended carbine stock.. It has two additional positions at 6.875″ and 8.375″.

You can set-up the stock with a myriad of buffer options to fit your rifle and tune it in. The stock is available in black and FDE.

The Maxim Defense CQB Stock isn’t built to be a safe queen, it’s made for real-world use. With the 4 available extension positions, you can dial in the stock for your body and function.

Installation was easier than expected. Just be sure to not launch your detent and spring for the rear take-down pin when you disassemble!

Once together, I was amazed by the compact size of this unit and the comfort of the adjustment points. I’m a tall fella at 6’6″ with gorilla arms and the Maxim Defense CQB Stock still adjusted out to fit me.

At the range, I had mentally prepared myself for failures on my short barrel suppressed work rifle using the generic buffer and spring and assumed I would have to contact Maxim for different variations of their product to dial it in. I was pleasantly surprised with it, not a single failure after about 200 rounds through it. Obviously it’s going to need some more put down range to put me at ease but I’m on the range next week for rifle training so we’ll push it then. The hex patterned and textured butt plate kept the stock welded in place while ringing my CTS Steel plates.

Overall opinion of this piece of equipment is that it is strong, quality craftsmanship that makes my rifle a better trunk monkey. I’m able to stow it in more compact spaces, deploy in the confines of the front seat of a patrol vehicle without smacking a windshield, and manipulate the rifle in the close quarter confines of the trashiest trailer house. Coupled with the Spikes Tactical Compressor upper, I’ll hopefully still be able to hear if I ever have to use it in the field without my hearing protection on.

Speaking of hearing protection – if you’re in a position to affect change within your agency, work towards getting suppressors on all department rifles. One incident in a confined space with the patrol rifle and you’re looking at a high likelihood of permanent hearing loss.

MSRP for the Maxim Defense CQB Stock is $395.00. Maxim Defense Industries offers a 30-day return policy.

Sharp’s Rifle Company AR-15 Xtreme Bolt Carrier Group

Sharp’s Rifle Company made quite the splash among YouTubers when it seemed every channel was reviewing the Xtreme Performance Bolt (XPB). While Sharp’s is known for some of their unique calibers like 25-45 Sharps, the XPB represents a product for the mainstream .223 and .300 BLK shooter. The AR-15 has gone through several evolutions and mutations in recent years with an explosion of improvements, but the bolt carrier group has been left rather unchanged. The XPB offers some claimed improvements. Here’s the breakdown as taken directly from the product website:

“The Sharps Xtreme Performance Bolt (XPB) Carrier Group Complete has the same design as the Balanced Bolt Carrier Group and is precisely machined from S7 tool steel. The XPB undergoes a 24-hour thermal cycle proprietary heat treatment and is finished with DLC (Diamond Like Carbon) Coating. The XPB Carrier Group Complete displays the SRC logo machine cut and visible when the ejection port door is open. The XPB fits standard AR-15/M16/M4 rifles chambered in .223/5.56mm, 25-45 Sharps and 300 Blackout calibers.

We offer a 30-Day Money Back Guarantee on our complete line of Sharps bolt and bolt carrier products.

V-TAB from Fast Acquisition: Accuracy Through Design

The V-TAB or Vertical Tactical Adjustable Buttstock from Fast Acquisition is a design concept to help the rifle shooter obtain a proper cheek weld when shooting. I’m surprised somebody hasn’t thought to build this product already!

When working with newer rifle shooters on the AR-15 style platform that have some experience on hunting style rifles, they often struggle with placement of the buttstock. Down in the pocket of the arm isn’t always the best place for that beautiful black rifle. With the V-TAB from Fast Acquisition, that new (or stubborn seasoned shooter) will be obtaining a proper cheek weld and placing the stock in the pocket for shooting due to its quick vertical adjustments.

The V-TAB M in the up for prone or bench rest shooting position

The V-TAB adjusts vertically in seconds with no tools. Once installed using the original or aftermarket buttpad, you are able to adjust up and down in seven different positions to accommodate standing, kneeling, benchrest, or prone stances and have the best sight to eye alignment possible. Click here to watch a video of the V-TAB in use.

The VTAB is machined from tough Delrin adding hardly any weight (6.7 oz.) to your build and increases the length of your buttpad by only 1.5″.

If you’re looking to bring accuracy to the next level of your black rifle build, you should consider adding the V-TAB from Fast Acquisition and “bring the gun-sight to your eye, not your eye to the gunsight.”

The V-TAB M in the center configuration adds minimal weight and length but maximum adjustment

The V-TAB fits on Magpul MOE 310 + 400, CTR, STR, ACS, ACS-L UBR and they are working on new designs everyday to add to the line up. Model shown is the V-TAB-M with an MSRP of $69.95, click here to buy now.

New Magpul Product Release: MAGPUL BIPOD – SLING STUD QD

The Magpul Bipod – Sling Stud QD is the next offering in the Magpul bipod line. Designed to mount to the ubiquitous Uncle Mike’s Sling Swivel Stud that is common to nearly every sporting rifle made, the Magpul Bipod – Sling Stud QD is the strongest, most fully featured bipod available with direct sling stud mounting. Offered with a new rapid-attach sling stud mounting system, the Sling Stud QD bipod takes the fuss of aligning and tightening that comes with traditional sling stud-mount bipods out of the equation. The stainless-steel mounting system self-locates and aligns perfectly every time, and an ergonomic thumb wheel allows for excellent grip to ensure easy tightening. Additionally, two sizes of high-durometer rubber mounting gaskets are provided to ensure optimized fit and load distribution on narrow sporter-contour or wider target-style forends. The ability to mount a sling on the forend is maintained with a low-profile sling stud on the rear of the Sling Stud QD mount, which also provides for a quick detachment when it’s needed.

Providing the same premium features available in the existing line of Magpul bipods, the Sling Stud QD bipod provides the high performance associated with higher-priced bipods at a significantly more affordable price for all shooters. Spring-tensioned, Mil-Spec hard anodized 6061-T6 and injection-molded reinforced polymer legs stow neatly forward and snap down and lock into place with one hand. Leg extensions slide and lock securely with the push of a button on any of the seven locking detents, extending from 6.7” to 10.0”. An industry-exclusive 50° of total tilt are controlled by a glove-friendly, knurled, tool-less, bipod locking knob located between the extended legs, allowing easy adjustment between shots. A soft rubber bipod locking knob cap is attached to the locking knob, giving users a steady, non-marring forward rest while the bipod is folded. Additionally, its staggered soft rubber feet hold fast on a variety of shooting surfaces and are easily removed with a roll pin punch. Should users choose to change feet, the Sling Stud QD’s legs accept most Atlas-pattern bipod replaceable feet. The streamlined housing and legs fit neatly under the barrel and are just under 2.3” deep and 3.3” wide when folded.

• Rapid leg deployment with efficient single-handed adjustability

• Rapid-attach, self-locating stainless-steel mounting system mounts to Uncle Mike’s Sling Studs on narrow or wide fore ends, while also providing a quick detachment capability
