    Well…..where do I start. My dad wanted an upgrade to his Talon SS. He ordered a brocock compatto from AOA. My dad has had his compatto now for a couple of weeks……and although this rifle is not mine…..I have shot it enough to review the rifle.
    We tried a wide assortment of pellets through the compatto. Unsurprisingly, the JSB 18.13 perform the best. Below is our 50 yard target from early this morning. I use a Nikon Acculon for all my rangefinding needs…..so its a legit 50yrds. Also……note these are not “cherry picked” groups. There are 40 shots on target from the compatto. Ten in top left, ten top right, ten center, and ten lower right. Bottom left was the Talon SS so disregard. The small squares on the target are one inch squares.

    Ten shots top left high power……

    Ten shots top right high power…..

    Ten shots center high power…

    Ten shots lower right medium power…best group of the day….

    The targets speak for themselves here. My dad has this rifle sighted for 40yrds….thus the drop at 50. Also….there is a very light film of plastic behind the paper that moves around freely. Its actually a styrofoam archery target that we stapled the target too. There are ten shots per group I swear it. The rifle is definitely quiet/backyard friendly with the huggett. I don’t have a decibal reader but it is noticeably quieter than his Talon SS. I love the way the scope mounts to the action and not the air cylinder or the barrel. Most all bullpups seem to have the same engineering hurdle to overcome……and that is how and where you mount the scope since the reciever is so far back. The compatto is a blend of traditional and bullpup……not quite either….but I do love the free floated barrel and the scope mounted to the reciever. We have not experienced point of impact changes……so there you go. The rifle balances directly under the trigger guard with the scope and bipod attached and feels good to shoulder……not front heavy at all. The trigger is set at 2 lbs. with no creep. First stage is smooth travel about 1/8th inch…..then a wall with no creep. I personally feel the trigger could be adjusted much lighter…..and to my liking…..but my dad hates my triggers which are set to 6 to 8 ounces. In the end its fully adjustable for anyones taste…..main point being there are no rough spots or creep.
    Below are some pics of our shot counts. The compatto is putting out 27 foot pounds of energy averaging about 820 fps with the 18.13gr jsb pellets. Curiously…..both the high and medium power shot strings were identical in both velocity and shot count on this particular rifle. Low power revealed 780fps. So…..no difference between high and medium….and 780 on low.

    Medium powershot string…..

    Pic of Chronograph used

    We found filling to 215 bar/3150 psi yeilded the best results for this particular rifle. The guage on the front of the rifle is only reading 5bar off from true…..not bad if you ask me given all the small guages used on pcp rifles. We get right at 20 really good shots per fill from the 150cc air reservoir and slingshot hammer system.
    The magazine is very smooth and slides into and out of the action very smooth. The magazine is spring loaded and auto indexes…..and is made of metal throughout…..a very high quality magazine of the same build quality as a daystate. The bolt cycles smoothly and feeds each JSB 18.13gr pellet smooth as well.
    The only 2 negatives I can find are the low shot string and the front of the synthetic stock. The shot count is respectable given the volume of the air cylinder. If hand pumping it should pump up fairly quickly. If your plinking you could be pumping often. If using a tank then no big deal. The extreme front end of the stock has a small amount, 1/8th inch, of side to side flex but no up and down flex. This is no way a deal breaker and does not seem to affect accuracy. I used 1 inch long pieces of black electrical tape on both sides of the air cyclinder right at the front of the stock to eliminate this play. The groups did not change at all.
    Lastly……and perhaps most importantly….my dad loves his new compatto. He loves the light weight and how it balances. My dad is older and does not like heavy rifles. He loves the accuracy, the trigger, the repeating aspect of the rifle and the magazine. That about sums it up. I like the rifle too. Would be an awesome rifle to tote in the woods.

    Interesting review.  If the high and low were the same I would look into whether or not you are actually getting the shift to take place. Sounds as if the port is not moving to be more open for the high or low setting and is stuck somewhere in between even though you are making the external changes.  Just my thoughts.  However a very good review with accuracy.  Actually while hunting with my older Brocock or other small cylinder rifle, I find 20 consistent shots are plenty unless I start plinking.  I carry a Gupy bottle to backup the air supply.
    Thanks for sharing…

    Thanks for the feedback. Oddly….the high and medium are the same…..low shaves off about 40fps. All four ten shot groups had the same poi at 50yrds…..3 were shot on high and one on medium. Either way….if it were my gun I would probably not fool around with it. I believe its advertised as a 27ft lb rifle and that is what its doing. Will be intresting to see if others experience the same with the power settings.

    I have a Compatto also and can attest to the power adjuster not really working.  On mine there is only 3-5fps different between high and medium and only about 50fps different on low and doesn’t add any to the shots to the string .  I just got a new hammer spring (from the local hardware store) and a Low Power Huma reg installed in mine and currently with the reg set to 90bar (1500psi) I get 60 shots at 700fps with JSB 16gr from a 200bar fill.  I do use a hand pump and I plink (in my backyard in town w/neighbors on 3 sides) more than hunt, and rarely hunt past 50 yards so this setup is great for me.  Everything Marksman3006 has said is spot on, even the bit about the fore end of the stock having an annoyingly small amount of play in between the cylinder and the stock.  Also Plano All Weather Tatical Case fits the gun great, and if you don’t mind taking off the Hugget to put it in the case then the 36″ will work (I returned my 36″ and got the 42″)

    Thanks Adam…….I had a hunch there was nothing really wrong with the rifle. I bet that sucker is stupid quiet at only 700fps with 15.89 jsb pellets. Good mod and shot string sounds like.

    Thank you for the technical review. You gave more insight into this medium power but crazy accurate gun. I wonder if the .25 air cyl. Can be pressurize to 215 bar? As i have shooting mine for 2 months. Real joy ,extremely quiet and drills through double .040 aluminum at 105 yds . Enjoy

    Thanks for the great review. I’m still trying to decide between the Compatto, Daystate Regal XL or the FX Wildcat.  It might come down to which one is the most quiet. Carl
    Beautiful property there.

    The power curve tells me where to charge the gun to. The first shot string I filled to 3000…..but I started off way to close to the peak of the bell curve so I knew there was a few more shots to be had with a little more pressure. The chronograph comes in handy.

Really it is a simple matter to solve. Buy all three! :P That was my solution! ;)

Between the Compatto and the Wildcat, the Wildcat wins handsdown in quietness. (Both the 30 fpe FAC models, both with a moderator, the WC with a Huggett the Comp with an HW). I do not own a Regal, but I do know that a MK4 with a Huggett is even much more silent than a Wildcat with a Huggett fitted. (The wildcat is extremely quiet, but a MK4 is ridiculously quiet!)

    Just a quick bump to note that I have a .177 Compatto. I was thinking of a .22, but read the reports of the power adjuster not doing much. (must be set for UK 12 FPE tune)

    On the .177:

    Low ~ 12.5 FPE
    Med ~ 17 FPE
    High ~ 18-19 FPE.

    Low is usefully different than medium and high, and notably quieter too.
    Medium is more accurate than high and very nearly as powerful.
    High, I only use when I feel like I really need that last couple of FPE, like on a raccoon or possum or something.

    They need to take the US market seriously and rework the power adjuster to make sensible differences, if they’re going to compete with FX, who seem to be on the ball, in this regard.

    I was looking at the Compatto but wanted to find a actual user’s feedback before “pulling the trigger”. This definitely helps. Thanks for sharing!

If you haven’t seen it yet, here’s my first impressions review of the Compatto, also comparing to Marauder. Might be helpful, esp. if you have Marauder experience.

    I read Smaug’s reply above where he says that he shoots mostly on medium power. I went out yesterday and was shooting my .177 on medium in my backyard at 30 yards. I filled to 3100 – 3150 psi and shot 40 pellets. My gauge was still in the green and I didn’t notice any drop on my target. The only knock I ever see on the Compatto is shot count. I disagree, I think 40 is great for this gun and air capacity. I’m loving this rifle!

    Great review on the Compatto.  I think it’s a great handling rifle, although I do not have one, just shouldered and handled it in the past.  

    The power the Compatto puts out even at medium level is more than enough if you plan to hunt small game even up to 50 yards.  I shoot nuisance pigeons that invade my property with my greatly powered-down Cricket (8 FPE) up to 27 yards with a headshot, and that’s all that’s needed to take them out cleanly.  The great thing about the low power is that I can get over 450 shots with an extreme spread of 12 FPS from a 220 BAR – 50 BAR fill; this is, of course, with the gun’s hammer spring, valve spring, and regulator tuned.

    I have been looking into the Compatto or Bantam for Field Target, based on the balance – more weight between your hands.  My current field target gun is way front heavy – AA S510, but I get 90 shots at 18.5 FPE.  I am concerned that the efficiency does not look that great on the Compatto.  I put Marksman3006’s medium numbers into my spreadsheet and I am only getting 0.94 FPE/CI efficiency.  Both the Compatto and Bantam look like they should offer quite a bit more.  For instance my Contour S6 (original version not the elite) can do 18 shots at 22 to 23 FPE and about 4 to 5% variation on that tiny tank.  I had to try a number of springs to get that effectiveness, so maybe the Compatto is not setup with the right springs and is over-driving the valve a bit.  I am also wondering if Marksman3006’s has the new slingshot valve system and if the power setting is just throttling teh transfer port and the efficiency falls off because if it.  I am interested to see what other folks are getting for their efficiency.  In doing my research Brocock is offering a FAC “Deluxe” package in England with two magazines, a bipod, and swivels for less than what is being sold by the US vendors.  I just need to find the right exporter in England to ship one of those to me.

    I just shot a string with a 225 bar fill on my .177 Compatto.

    40 shots at 18 FPE on medium power from a 150cc tube seems pretty efficient to me.

    Update. This is my favorite airgun. Every other gun just feels a bit “off” compared to this one. This one is just long enough, no cocking lever by the ear. The only one that’s close is the .22 Air Arms S510. It is quite long and muzzle-heavy, compared to the Compatto, esp. by the time one has silenced it properly. (it’s 52″ with the 6″ TKO!)

    I filled it to 225 bar tonight, and shot it with its favorite pellet, the Air Arms Heavy, 10.3 gr..

    Obviously, those numbers would improve quite a bit if the string only went from Shot 10 to Shot 50.

    40 shots @ 18 FPE from a little 150cc air tube is pretty outstanding efficiency. The Huggett is also really efficient; I can’t recommend it highly enough.

    Earlier testing showed about a 1 FPE energy boost by going to high power, and less accuracy, so I only go there for short range nighttime pests, when I really want to reach into them deeply.

    Recommendation: Fill to 3k psi, shoot 4 mags @ medium power before refilling.

    SMAUG, That string for the 177 works out to be 1.39, which is pretty good. I suspect that the Marksman3006’s may not have the slingshot hammer. His efficiency is about a well tuned PCP without a hammer denounce device. It is still good, but could be much better. Are you considering a regulator?

    Reese, other than the play in the stock, how is the build quality? Good review by the way.
