The Tapco T6 Butt-Pad attaches to the butt of most M4s with adjustable stocks, compatible with both airsoft rifles and real ones.

The T6 Butt-Pad pops right onto most M4 style rifles with adjustable/collapsible stocks without any glue, tape, or any other bonding agent. It also pops right back off very easily if you pull on it, but it’s still snug enough that it won’t fall off in the middle of shooting. To give you an example of what type of stock works best, the T6 fits perfectly onto my personal JG M4 2010 Upgraded Version as well as the Crosman Stinger R34 airsoft rifles.

The T6 definitely helps the butt of your gun to stay up on your shoulder, especially if you’re wearing a backpack or a vest where there’s a strap right where the stock rests. It also takes off some of the impact that your shoulder gets from recoil on real guns.

The T6 also adds a full inch the the length of your gun, which can be both good and bad. If you have longer arms, you might benefit from the extra length. But if you already have your stock at a perfect length, the extension might make your rifle feel awkward. Although, truthfully, an extra inch doesn’t make that big of a difference on my personal airsoft rifles, and, besides, the T6 only fits onto adjustable stocks like I’ve mentioned, so you should be able to just adjust your stock an inch inward if you really don’t like the extra length.

It’s also extremely durable. It’s made fully of rubber, and can hold up to just about any climate or terrain you can throw at it.

In a wrap, the Tapco T6 Butt-Pad is a durable and cheap attachment for any M4. It works with both airsoft and real firearms and keeps your rifle up on your shoulder. The only down-side is the extra length, which isn’t even that big of a deal.
