Worked well for my application - UTG Pro AR308 6-position Receiver Extension Tube

I used this to swap out the factory stock on an Armscor TM22 and dropped a Magpul CTR on it so I would have QD and more length. When fully exetended it gave me about an additional 3 inches over the fixed factory stock. That was exactly what I was after. So the little bit of extra length this stube had was just the ticket for my needs. Took about 10 minutes to install all the parts including a MVG and QD mount. Gun is much more conmfortable to shoulder and sight down now. This made a really good accurate little bargaain 22 a great little 22. If you want a bit more length this is just the thing. Nope I was not putting it on a 308 but it was perfect for my needs. The only neagative was that shipping was very slow and it took 10 days to arrive (from IL to TN that seems like a lot).
