Things I liked:Metal alloy mounts. Things I would have changed:Allen head socket screws could be harder. This may be the design however, to keep the ham fisted from stripping the thread mount. Just something to note during installation. What others should know:Used these mounts to fit a Tasco red dot on my Crosman 1377. The mounts do not move and the scope has tightened my group considerably. I highly recommend this combo.
Things I liked:Nice round, smooth surface finish. Things I would have changed:Nothing. What others should know:I inspected the surface finish of the Daisy Avanti and some Copperhead using a 10X lighted magnifier. The surface finish of the Avanti was smooth and round with minimal nicks and scratches (think a ball bearing without the high polishing). The Copperhead looked more like the moons surface with uneven copper coating, deep depressions and inclusions. If your looking for accuracy, pick up the Avanti. You'll be glad you did.
Things I liked:The grip angle is more like a (centerfire) Springfield XD then Glock. I find it points very naturally. The stippling on the grip panels is very much like generation 3 Glock, as are the finger grooves. Trigger pull is excellent and feels like a heavily modded (centerfire) Glock. All other features (mag/slide release, take-down release etc. are in the same location and remind one of Glock. Things I would have changed:Sights move very easily. They will need to be Loctited after sighting in. The pistol comes with combat sights. An option for rear adjustable (windage & elevation would be nice to compensate for various weight BB's. A (6.01mm) tight barrel supplied from the factory. This is a high quality pistol, but has a short barrel and I found factory accuracy lacking. What others should know:I purchased this pistol to prepare for an upcoming force-on-force training course. Originally, I was looking to duplicate my carry centerfire Glock. Cruising the foreign websites (where airsoft Glocks are still available) I quickly found out that the upgrades (metal slide, hop-up, nozzles etc.) needed to make the airsoft Glock close to the ATP would cost 2-3 times the price! I purchased the ATP and have not looked back. I replaced the factory barrel with a 6.01mm (KWA) tight barrel, reducing group size about 50%. KWA's (45 day) factory warranty is void if other than green gas is used. Pistol is shipped with no lubricant applied to any of the wear, o-ring or rubber surfaces. Factory manual explains break-down OK, just be aware. Make sure the magazine follower is lubricated as feed failure and slide locking on empty may be affected. Fill the mags with gas first, as the BB follower spring compresses the bumper spring making release more difficult. The 3/8" thick rubber bumper on the magazines must be slid forward or removed to fill mags with gas as the fill nozzle can't seal with it in place.
The ATP is supposed to fit Glock holsters, I tried it in Kydex models from FOBUS (model EMG) and BLACKHAWK (model CQB). While the ATP fit, it would not engage the retention system of either model. So take your ATP with you or look for ATP specific holsters when shopping. I have about 1500 rounds through this ATP with no problems and enjoy it (maybe more) than my centerfire!
