Have no clue, why Fwb show on their site the Mod 700 frames/airguns without the side 'vents' or holes, on the frame.. I really thought the flush alu "A" frame (is that what its called ? ) without holes, was the OLD type... To get more confused , I also discovered there are 3 types of Mod 700 - some with 3 holes, and some with 4 !! And we are not talking after market do it yourself, or custom mods to the frame...this is obviously coming straight out from the Fwb factory.. Which is the newest in terms of manufacturing time line dates ? a. Flush (no holes) b. 3 holes c. 4 holes See the pics...and you'll understand what I mean.
