Things I liked: 1) Metal work is well executed, without any objectionable toolmarks. 2) Polishing and bluing (actual a blackening) is uniform and dark under strong light. 3) The vast majority of the stock work is clean and well executed save for one problem (see below). 4) Trigger has a smooth second stage and the break is crisp and repeatable. Out-of-box my trigger broke at around 19 Oz. on my very old RCBS spring scale. After 300 rounds it breaks at 16-16.5 OZ. 5) Fully charging to 200 Bar and following the recommended recharge at 100 Bar I am getting about 150 rounds. You'll get 2 full practice sessions between charges. Given the small size of the cylinder (~100 cc) this rifle is easy to run with a pump. 6) The stock and trigger have plenty of adjustability. 7) Accuracy is excellent. My best 5 shot group to date has been 0.225" O.A.L with the 8.2 gr RWS Meisterkugeln pellets (prone, @ 10 meters, stock Gamo style rear sight and 3.0MM front insert.) The rifle is capable of better.

Things I would have changed: 1) There is obvious tool chatter and grain tear out in the corners of the 6 cutouts at the air cylinder channel. I would not consider this to be normal on a $1000 rifle. 2) The aperture insert pre-installed in the front sight was badly bent. The sight's ears were too big for the slots in the sight tunnel and when the factory tightened the retainer the aperture was bent. None of my other inserts (from Anschutz) would fit either. A few carefully strokes on the sight tunnel slots with a needle file fixed that. I was able to flatten the bent insert with the help of a bench vise and a small brass hammer. 3) The bolt handle is too lightly constructed for my tastes and seems out of place in comparison to the rest of the rifle's build. I have noticed that if I retract the bolt too slowly the action will sometimes not cock- the lock work seems to need a little bolt speed. 4) The supplied front sight riser is flimsy plastic. Spend $5 and give the rifle the steel riser it deserves.

What others should know: 1) The length of pull is quite short out-of-box, probably too short for most adult men. You will need to buy or make spacers to suit your needs. I added the optional adjustable metal butt plate to mine and have been happy with it. 2) If you use a sling you will need the optional rail insert (Harris HBA-ANS). For what its worth, the Daisy sling from my 953 fit just fine. 3) I had Pyramid test my rifle. Their tested velocities were from 473-507 FPS with the 7 gr RWS Diablo Basic. My first generation Shooting Chrony is showing 450-481 with 8.2 gr Meisterkugeln pellets at the 150 Bar point on the rifle's pressure gauge. This is my first PCP rifle, so I am not sure how good the 31 FPS ES is. 4) The air shroud is quite long making cleaning a bit more difficult. You will need a high quality one piece rod or better yet a pull through inserted from the breach. The shroud can be removed by loosening a single set screw but I don't like doing this as it disturbs my sight adjustments

Things I liked: Got the rifle a couple of hours ago. Rifle looks beatiful, the finish is vey nice. Unfortunately I have not tried it yet cause there's an issue with the stock. Will update or create a new review when I get the replacement. The low rating is for what I've received.

Things I would have changed: Air Arms should have better Quality Control. The rifle that i received have a crack on the pistol grip that's been glued, even have glue residue around the crack. I can't believe Air Arms sent this to Pyramiyd to sell as a new Rifle.

What others should know: Still waiting for a response from Pyramyd to get an RMA so I can swap this thing. Hopefully this is just an isolated case of bad QA. I will update this once I get the replacement and have tested the gun. I also hope Pyramyd Air have a good customer service and take care of this quickly.

Things I liked: I love the feel ov the gun when I am shooting it. I blame its slight lack of accuracy on my old eyes and not the gun. When I talked to the rep. I ask for a gun that if I missed I would know it was me and not the gun. I got a beaut.

Things I would have changed: As others, I would like to see a Foster quick fill on the tank.

What others should know: Buy it, shoot it, love it.
