The Compatto – Brocock’s Rebirth
Launched in 2015, the Compatto is the first rifle to be released by Brocock after being acquired by the same owners as Daystate and MTC Optics. The Compatto was designed from the ground up to be a rugged, compact and lightweight rifle. Brocock wanted an effective rifle, equally at home shooting targets off a bench as well as being dragged around in the field for small game purposes. The bar was set high, as this rifle would set the stage for the future of Brocock as a company. The Compatto was a success, with the sub 12FPE variant rapidly gaining a loyal following, and reassuring fans that Brocock’s new owners were dedicated to continuing to support the brand.
Carrying on the curves of the Concept and Contour
The skeletonized thumb-hole stock of the Brocock Compatto pays homage to one of their more popular rifles of recent years, the recently discontinued Countour series of PCP air rifles. With the new Compatto, Brocock has opted for a rugged, black synthetic stock, giving this semi-bullpup a modern look and feel, while keeping the overall weight down to a reasonable level. The design of this stock makes it amazing as a field gun. It is easy to handle and carry, and quite simple to attach a sling to or even just tie off with a section of paracord. The built in front accessory rail allows to to add a biopd, flashlight, or your choice of accessories with ease.

The .22 Compatto comes with a 10 shot, self indexing magazine. It is a straight forward and basic design, and is very easy to repair should you encounter problems with it. I say this from experience, as during the course of testing the updated Compatto, I ran into some problems as a result of a deformed pellet. This caused the magazine spring to bind up, and the magazine would no longer index. Fixing it was a simple affair, involving loosening 2 screws and resetting the main coil spring on the magazine. With that said, I am still a fan of this magazine, and feel it is one of the better self indexing ones on the market today.
Updates to the FAC/Full Power Compatto
When the Compatto was first released, the FAC or full power version, while a nice rifle, was not without it’s faults. It lacked the Harper Slingshot Hammer system found in the sub 12FPE variant of the Compatto. The result of this was 20 effective hunting power level shots, after which the velocity drop off was significant. In addition, the power adjuster on the initial FAC rifles had a minimal effect, resulting in a change of only a few FPE from High to Low power.
The updates to the Brocock Compatto address these issues. First, Brocock worked with Daystate to developed an improved version of the slingshot hammer system, one which would work in the FAC Compatto. The immediate result was close to a 50% increase in acceptable shot count*. Additionally, the power adjuster was updated, and now allows to go from a high of 27FPE to a low of sub 14FPE on the FAC version.
Shooting Consistency and Power
After filling the rifle to the suggested fill of 230BAR* (Please see note below) we began testing the Compatto with different pellets and power settings. On the rifle we tested, the power adjuster yielded results of 27FPE on High, 25FPE on Medium and 10FPE on Low power. What impressed me most however was the shot to shot FPS consistency. The first 16 shots using JSB 15.9g .22 pellets resulted in a 16FPS velocity spread, or an Extreme Spread % of 1.82%. This was pretty amazing, and rivals that of many fully regulated rifles. At 30 shots, the spread rises to 46FPS, or a little over 5%. With a high shot speed of of 881FPS, low of 835FPS and average of 865FPS, this made for 30 great hunting shots.
For this final graph, I compared numbers from the Updated version of the Compatto to a pre-update model. Both were filled to the same starting pressure. The numbers don’t lie, the updated Compatto provides quite the improvement in consistency.
Two things to note here. First, I am not, nor have I ever claimed to be, a great shot. I’d call myself an average shot at best. Secondly, these shots are from three different sessions.
The next groups are all 10 shot groups.
The following are a full string of 30 shots, 10 per target at 75 yards
Final thoughts – Cannot wait to see what Brocock has in store for us!
There are two complaints I have about the Compatto. First, I wish it came with a larger air cylinder, even if it meant a slight increase in overall weight. While they are able to get an amazing 30 shots out of the small 150cc cylinder, I would love to see what they could produce with a larger air reservoir. Secondly, I wish it came with a picatinny rail instead of the standard dovetail. I find myself swapping between different scopes these days both for review purposes and in order to swap out for my ATN Night sight. On the Compatto I addressed this with an adapter, but having the Picatinny rail would have been a nice touch, especially seeing as they are already using one for the accessory rail on the front of the stock.
Aside from that, I really enjoyed my time with the Compatto. It can see it as a great field gun, and look forward to taking it out for some small game hunting. The rugged synthetic stock means I don’t have to worry about dragging it through the woods, and the light weight and rearward weight distribution as a result of it being a semi-bullpup should both be huge assets in the field.
I will admit to being very surprised at how well this rifle performed at longer ranges, and more importantly, how easy it was to shoot off-hand, something which I normally fail miserably at. It was a quiet rifle with the Hugget moderator installed, and was both backyard and basement friendly.
At this time, I believe it to be a decent value as far as PCP air rifles go. I really look forward to seeing what other surprises Brocock has in store for us in the coming months.
* Note- To achieve this shot count with the updated Compatto, it is necessary to fill the rifle to 230BAR. While this is currently the suggested fill level as per the USA importer of the Compatto, the documentation and on rifle markings for cylinder pressure still reflect a 200BAR maximum fill. AirgunsARP.com does not recommend this 230BAR fill pressure (for liability reasons) in so much as we are just passing on the suggestions we ourselves received in regards to the updated rifle.
