I wanted better accuracy on my Spike's HAVOC / Kaos system so I added an LMT Leaf Sight I got used off of Grogs 40mm forum. Now it is finished and about as good as it is going to be. I am very satisfied with the way it came out.

Do you happen to know if an LMT M203 will fit on the Kaos rail like the Havoc as far as length goes?
Looks great!
I have been thinking about a spikes 37mm launcher.
I have a couple of questions, Spikes did not answer. thought you might know.
If I register it as a DD I can shoot all kinds of things, but if want to upgrade to a rifled 40mm barrel would a LMT barrel fit?
I asked spikes If any other 40mm barrel would fit IF I paid my tax, and all they would say is we don't make a 40mm barrel.
I fallowed up with I understand you don't make one, but is yours made to be compatible with anyother? no response.
I write it off as I am not yet a paying customer and they don't know the answer. You might not know either, but I thought I would ask.
any help you can give would go a long way in helping make the decision to get the 37mm launcher.
thanks.
LMT barrels will not fit off the shelf. The rails are different sizes.
You could, however, buy a LMT barrel and modify it at a machine shop to fit by either adding a different rail or modifying the one on it. GROG
thanks Grog
that is just what I wanted to know.
