FOR TACTICAL USE, DANIEL DEFENSE’S M4V7 PISTOL PERFORMS LIKE A PRO
If you’re looking for a pistol that performs like a pro in tactical scenarios, look no further than Daniel Defense’s M4V7. By Richard Schutz
Whether you think of it as a truck gun, pistol or just a home defense weapon, the Daniel Defense DDM4V7 P is one mighty handy weapon. Chamber it in .300 Blk and put a suppressor on it, and it would be one mighty handy, quiet weapon.
No matter where you keep it, next to the nightstand, behind the seat of your truck or behind the back door, this “pistol” will bring a lot of firepower to the fight in a hurry.
The DDM4V7 P is classified by the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) as a pistol and can be transferred as such. Since the advent of the pistol arm brace, the BATFE has issued several letters of interpretation regarding how the use of a pistol arm brace affects or changes the design and therefore the legality of the firearm. In the most recent letter, dated March 21, 2017, the BATFE determined that shouldering a pistol with the stabilizing brace did not constitute a “redesign” of the firearm and therefore it was not illegal to do so.
When firing the DDM4V7 P, make sure that you understand the latest letter(s) of interpretation by the BATFE. They have changed their position before, so they certainly could change it again, depending upon the party in power on Pennsylvania Avenue.
Other than the pistol-stabilizing arm brace, the DDM4V7 P is very similar to the rest of Daniel Defense’s line of AR-15 rifles.
The DDM4V7 P that was used for this evaluation was chambered in 5.56mm NATO. It accepts virtually any AR-15 style magazine and will fire both 5.56 NATO and .223 Remington ammunition. A version chambered in .300 Blk is also available.
As a direct impingement (D.I.) style AR-15, Daniel Defense had to jump through a few hoops to come up with a folding stock. Since a D.I. AR-15 requires a buffer tube with a spring and buffer mass, they couldn’t just attach a normal folding stock to the lower receiver as can be done on a gas piston operated AR.
The key to the folding stock is the use of a LAW Tactical Gen 3-M Folding Stock Adapter. The LAW adapter is installed between the lower receiver and the buffer tube portion of the stock assembly. A LAW Toolless Bolt Carrier Extension is installed in the rear of the stock bolt carrier to make up for the added length of the LAW Tactical adapter. It is extremely important to remember that the DDM4V7 P cannot be fired when the stock is in the folded position. When the stock is folded, the adapter is very plainly marked to this affect.
Another important piece of the puzzle is the SB Tactical SOB pistol stabilizing brace. This takes the place of a traditional stock and, along with other criteria, allows the assembly to be considered a pistol rather than an SBR. As such, no tax stamp and related NFA paperwork is required for the transfer of the DDM4V7 P.
SB Tactical offers several versions of the pistol-stabilizing brace. The SOB is a slim adaptation of their SBM4 model. It is made from a stiff, yet pliable rubberized material and uses a hook-and-loop strap to secure the brace to your arm.
Daniel Defense spares nothing when it comes to building a high-quality firearm. The upper receiver is CNC machined from 7075-T6 aluminum and has M4 feed ramps. The bolt carrier group has a M16 profile, is chrome lined and is magnetic particle inspected for subsurface defects. A 10.3-inch-long chrome-lined cold-hammer-forged barrel made of chromium molybdenum vanadium steel is used. It is turned to government profile and is Mil-spec heavy-phosphate coated. The rifling twist rate is 1:7 inches. A Daniel Defense 17-4 PH stainless steel flash suppressor is attached using 1/2-28 TPI threads. A polymer dust cover and a forward assist are also provided. Machined from 6061-T6 aluminum, a Daniel Defense MFR 9.0 M-LOK

handguard is attached to the upper receiver, which features Daniel Defense’s patented rail mounting system, with four grade-8 Mil-spec fasteners. At the 12 o’clock position on the handguard is a full-length 1913 Mil-std rail, which matches up perfectly with the rail on the upper receiver. The gas system is carbine length and uses a low profile 4140 hardened steel gas block.
The lower receiver is also CNCmachined from 7075-T6 aluminum. It features a flared magazine well and a rear QD swivel attachment point. An H buffer is used. The pistol grip, which is Daniel Defense’s own design, utilizes glass-filled polymer with soft-touch overmolding.
I did not find it mentioned in the Instructions/safety/maintenance Manual, but there is a trick to disassembling the DDM4V7 P for cleaning. When the rear takedown pin is removed, the BCG with the LAW Toolless Bolt Carrier Extension installed will not allow the lower receiver to rotate around the forward pivot pin. Therefore, it is necessary to either fold the stock and remove the bolt carrier extension prior to disassembly, or to remove both the front and rear disassembly pins and separate the upper and lower halves by rotating the front of the upper receiver upwards, and then pulling it forward so that the bolt carrier extension clears the lower receiver. In my mind, this is the preferred method so that you don’t forget to reinstall the LAW Toolless Bolt Carrier Extension into the bolt carrier after reassembly.
Other than the items above related to the pistol-stabilizing brace and folding stock adapter, the DDM4V7 P operates just like any other D.I. AR-15.
AMMUNITION & MAGAZINES
I used several different brands of magazines, including the 32-round DD magazine provided, various generations of Magpul magazines in 10-, 20- and 30-round capacities and C Products Defense 30-round magazines. All performed without so much as a hiccup.
Ammunition functioned just like the magazines, no hiccups. I fed the DDM4V7 P eight different types of ammunition from eight different manufacturers, and it showed no preference as far as function is concerned. It fed, chambered, fired and ejected them all equally well. Bullet weights ranged from 52 to 77 grains. All bullets were FMJ or OTM style.
I compared muzzle velocity for the ammunition used for this evaluation with the muzzle velocities for the same ammunition fired in two AR15s with 16-inch barrels that I had previously evaluated. The DDM4V7 P, with its 10.3-inch barrel, lost an average of 367 fps, or 63 fps/inch compared to the rifles.
The pistol comes with rail-mounted Daniel Defense Rock & Lock front and rear sights. The rear sight has large and small apertures, adjustable for windage. The post front sight is adjustable for elevation and features protective wings on each side. Both sights are machined from 6061-T6 aluminum so they are lightweight and rugged. For accuracy testing at the range, I installed my go-to combination of a Nightforce ATACR 7-35x56 F1 riflescope with a Nightforce 30mm Ultralite Unimount 20 MOA mount. This is a
The Daniel Defense DDM4V7 P as it came out of the box with “Rock & Lock” sights, soft- touch overmolding pistol grip, LAW Tactical Gen 3- M Folding Stock Adapter and SB Tactical SOB pistol- stabilizing brace. The receiver and handguard are finished in Cerakote Mil- Spec+.
The muzzle device is a Daniel Defense stainless steel flash suppressor with a nitride finish.
Daniel Defense used a LAW Tactical Gen 3- M Folding Stock Adapter to allow the SOB arm brace to fold 180 degrees. The release button is protected by a boss on the receiver half of the adapter so that the stock isn’t inadvertently folded while the pistol is in use.
The folded SOB pistol- stabilizing brace rests neatly alongside the receiver. It does not touch the receiver or hit the bolt catch lever.
