Too true, it will be good to hear all about the model once they have been put to the acid test by the hardest critics around.........airgunning enthusiasts.

Don't we just love to dissect every last model, for all the gossip and debate the pros and cons until the subject matter is exhausted!

Its my opinion that the Crosman model will have been thoroughly researched, developed and tested. It will have been set at sensible power levels for the configuration of the rifle and will most likely be a HUGE success. That can only be good.

If it does prove to be a great model, I forsee gas rams replacing coil springs as a motive power for air rifles in the future. There is much knowledge about coil spring rifles that applies to them also. Put this together with the gas ram technology and we shall see a big leap forward in performance, consistency and reliability.

Good news!
I tested out my gas ram Gamo CFX, to which I added the "Tourna Grip" tennis racquet grip tape.
I have now put several hundred rounds through this rig, and the accuracy was all that I had hoped (sub 1/2" five shot groups @ 25 yards).
Oh, I also clocked five shots each of all my pellets that I use with the rifle, and the velocity is either right about where it was with the original spring, or just slightly lower.
The consistency of some of the pellets in MV is impressive, especially the H&N Baracuda (also known as the Beeman Kodiak) heavy pellets, which varied only 3fps!
The scope has not moved at all, thanks to the tape, and I see no problems with the scope getting battered to pieces, as some claim their own gas rams did.
FWIW, the scope in question is the Centerpoint 3-9x40 adjustable objective, a VERY good scope for a springer/gas ram.
So, the upshot of this,for anyone thinking about stepping up to a gas ram, is that you might just want to consider getting a roll of the "Tourna Grip" tape at the sporting goods department of your local Wal-Mart, cut two three-inch long strips of it, then carefully (it was a bit tricky getting it in there neatly) clamp the rings over it.
I have now gone form a scope that slid rearward over an inch to one that has not budged even slightly.

Okay, time to go hunting!
