Most Helpful Positive Review tricky install
Directions are poor but a bit of playing around and it installed perfectly. It’s a 3 position stock 1. Fully extended 2. Mid extension 3. Fully collapsed To install make sure the nut in the pistol grip is properly seated in the nut cutout of the pistol grip. Do Not install the stock yet! Remov...

m4 tactical adjustable telescopic stock

by Sniper 1, Verified Owner from ID, United States Written on July 29, 2025
These pieces are awesome they look great once they're on your rifle but if you buy a Mac 1014 you will also need to buy the collapsible stock itself which is another $50 so be aware

Collapsible, not my experience!

by Philippe, Verified Owner from RI, United States Written on March 16, 2025
My experience with optics was great. Quick shipping and all BUT that collapsible stock is a piece of junk in my experience. My gunsmith had a "good" time installing it and now the "thing" is stuck on the shorter run (closer to the trigger) and I cannot get it unstuck! So, I will have to bring it to the gunsmith to get it either fixed or throw it in the dumpster and get on from Urbino & pistol grip...I guess you pay for what you get. Bummer, I really wanted to get it work. Cheers!

Panzer Adjustable M4 Stock

by JB, Verified Owner from OH, United States Written on January 20, 2025
Love the look and beefy! Gonna add some weight to an already heavy gun AND you’ll need to get creative for a rear sling attachment point (that’s not a QD hole �). Will also need some patience as the nut plate that threads the stock onto the recoil tube will need to be timed to properly align the stock. Overall, a nice addition for the price!
Pros:
  • well made
  • Inexpensive
  • beefy
  • stable
Cons:
  • Heavy
  • poor install instructions
  • No QD point
Best Used for:
  • Home Defense
Would recommend: Yes

Probably need a replacement buffer tube

by Copenasty, Verified Owner from AL, United States Written on December 17, 2024
Everything you need is not in the box. I’m going to need a replacement buffer tube for my panzer m4 with more threads that will allow the nut to be installed. I’ve got one order and hope that I can finally install this awesome stock.

Perfect for the Panelli M4

by Nicolas B, Verified Owner from FL, United States Written on November 24, 2024
The telescoping stock for the Panzer M4 semi-auto shotgun is a game-changer for shooters seeking both versatility and comfort. Right out of the box, the build quality is impressive. The stock is constructed from high-grade materials, providing a lightweight yet sturdy feel that holds up under heavy use.

Adjustability is where this stock truly shines. The telescoping feature allows for multiple length-of-pull settings, making it an excellent choice for shooters of all sizes or those wearing bulky gear. Whether you're using the shotgun for home defense, tactical training, or sport shooting, this stock adapts seamlessly to your needs.

The installation process was straightforward, with clear instructions and a snug fit to the Panzer M4. Once installed, it feels incredibly secure with no wobble, even under recoil. The ergonomic design, including a well-placed rubberized buttpad, significantly reduces felt recoil and improves overall handling.

Another notable feature is its sleek, tactical design, which enhances the aesthetics of the Panzer M4 without compromising functionality. The lightweight design ensures that it doesn’t add unnecessary weight to the firearm, maintaining its maneuverability.

Overall, this telescoping stock is a worthwhile upgrade for any Panzer M4 owner. Its combination of durability, adjustability, and ergonomic benefits makes it a practical and reliable addition. Highly recommended for anyone looking to enhance their shooting experience.
Pros:
  • Easy to install
Cons:
  • None
Best Used for:
  • sport
  • Huntig/scouting

OpticPlanet gets 5 stars for Customer Service

by Gabe M4, Verified Owner from TX, United States Written on October 31, 2024
I initially had an issue with my first order and the nut not going on the buffer tube and the actual stock kept getting stuck. Optics Planet exchanged the adjustable stock with no problem and great service. My new order the stock was perfect but again the nut wouldn't go on the buffer tube. Took a mallet and a couple of taps and it popped on. Now i have a properly functioning adjustable stock. I haven't taken it to the range as of yet but so far I'm happy. At 5'7 inches the middle position is the best for my arm length. Making the M4 Amazing.
Pros:
  • customer service excellent
Cons:
  • None
