(3 customer reviews)


The VLTOR A5 Stock Combo Kit is not just an EMOD stock with M4 components; it was developed as a completely new operating system. Specifically developed on the request of the USMC, the A5 combo kit is considered to be the most innovative upgrade for the AR platform, increasing the reliability, accuracy and performance of any weapon.

Export Control:

1. Do I have to use the VLTOR A5 spring and buffer with this system?

Yes. The A5 tube is physically longer than the normal M4 receiver extension and you must use a rifle length spring and the VLTOR A5 buffers.

2. What if I need a heavier or lighter buffer for my weapon?

The A5 kit was specifically developed to use different weight buffers depending on your need. There are 5 different weights to allow you to fine tune your weapon. The weights are: 3.8oz, 4.56oz, 5.3oz, 6.08oz, and 6.83oz. The A5 combo kit comes with the A5H2 buffer. While we sell different buffer weights, the A5 combo kit is only sent with the A5H2 buffer and we do not offer substitutions. You can purchase the different pieces to the A5 kit from our webstore.

3. Will the A5 system work on my .308 platform?

The A5 system is not compatible with the .308 platform.

4. What AR-15 platforms is the A5 compatible with?

The A5 system works with both direct impingement systems as well as piston driven systems.

5. What if I want to utilize the A5 system but use a different stock?

You can absolutely use a different stock on the A5 system. You would need to make sure that it is a Mil-Spec dimensioned stock. Please take note, most AR-15 type stocks will not collapse all the way down to the last position due to the A5 receiver extension being longer than a traditional M4 receiver extension. If you do want to use a different stock or the VLTOR IMOD stock with the A5 components and have your stock collapse all the way down, we do sell a different A5 extension that will allow this. It is the VLTOR RE-10/A5SR. It is a six position Mil-Spec A5 receiver extension. This receiver extension is slightly shorter to allow for the stock to collapse all the way down. You must use the A5 spring and buffer kit for this receiver extension.

    Slow is smooth and smooth is fast is all I can say about the butt stock. It came with my stock for my M1a. It is well made no rattles and says locked in position. Easy to find spot well, and and shoot. Match this stock with the customer service and they are second to none. I wish I had found them along time ago it would have saved me a lot of money and junk now in my junk box:)

    This is a great kit. Not only does it handle well, lock solid, provide an excellent swell for cheek placement, and provide a great range of positions, but the provided buffer and spring provide real versatility. I can put my 6x45mm upper on the lower, stretch out the stock, and shoot heavy loads of 85grain bullets with perfect functioning. Then I can switch to my 5.56 upper and shoot 45 and 55 grain light plinking loads all without any functioning issues. No buffer weight or spring change required. This kit is worth EVERY PENNY! Just buy it!
