Review of Brocock AimX Grand Prix .177
Bought this from B.A.R, price £275, condition new, it comes in a basic brown cardboard box padded in egg shell foam, and included was a Daystate style filling connector and a rather basic, single instruction sheet plus warranty/registration form.
First impressions were that it looked like a Falcon pistol (new style), build and finish quality of metal and wood work all looked good, it was not as heavy as it looks and felt pretty good in the hand, the cocking method which is by a spring loaded bolt with release catch seemed pretty smooth and light and trigger release was good also for a sporter style trigger (better than my titan/falcon).
With the 10 inch barrel (measured) the muzzle noise was less than expected so I assumed it was putting out about 3-4 ft-lb.
After a closer inspection of the action I noticed that the main and single piece steel pressure tube was painted just like a daystate, the receiver was anodised aluminium with a blued steel barrel which was threaded for 10mm (doh), B.A.R sell an silencer adapter for £20 which I thought was far too expensive so I left it were it was!
Though Brocock are bringing out a dedicated silencer soon…….
On returning home my first job was to compare it to my Titan pistol as the stocks looked very similar (I was hoping to swap the stocks over as the titans is a dedicated right hander rather than an ambi and of a much higher standard of wood) but at first glance that’s all it was similar!. The manual, basic as it was did state that it was designed and built by them so until I find anything to the contrary, then I believe that they may have just used a mixture of designs from other sources..
I then removed the stock by it’s single bolt (to oil the stock and check out the trigger block) the stock is very light but tough, what the wood is, I’m not sure ( looks like beech but feels like walnut) and the trigger block is made very well!
Over all I’m impressed.
now all I have to do for my next test is fill it with air and put it over my chrono To find the correct fill pressure, shots per fill and consistency.
Well here it is,

35. bad shot 70. 534
The final pressure reading was approx 110 bar
Maximum spread of .553 ftlb / 27fps over 71 shots.
For a sporter pistol, I think that these are all usable shots!
But as you can see from the table you can improve on this if you use shot 15 thru to shot 65. This will give you 50 very good shots with an overall spread of only 16 fps (now that’s acceptable on a rifle).
