Hey there, nice work so far!
I downloaded your V1.1 SPR and played with it some...
Some Constructive Suggestions:
The model looks pretty good so far, the textures could be a little higher res (they look like OFP 1.0 textures, but you are already working on this I guess) but overall, it looks very nice. The Bipod could use a little more detail.
The accuracy needs to be tighter; I can shoot better groups with a stock M-4 with Iron sights ( In the real world and in OFP). The rounds also tend to drift way to the right of the crosshair.
The recoil is about right in terms of impulse, but it seems like the timing is kind of off somehow.
I like the pics of the green camo version, when can I download a copy?
Definitely include versions with both types of stocks and with suppressors. As far as a "combat SF version"...To be perfectly honest, thats what the M4 SOPMOD is for. Putting an ACOG on a SPR chassis is like puting a governor on a Ferrari to set it's max speed at 55 mph.
