Gamo Big Bore TC35 PCP Air Rifle

Everything but the low scope mount.

Something is wrong with my TC35. It will not take any more air than about 2000 lbs. I pump or valve the gun to this level, and any attempt at pumping more air in results in a "click" noise near the foster fill nozzle, and any air in the fill hose is then vented. Air in the cylinder remains the same, but will not allow more than about 135-138 bar. I messaged Gamo and have only had one response from them, and that was just a question about the pump I was using (which works perfectly on all my other PCPs). I'd really like to shoot this gun, but won't as long as something is wrong with the fill system.....not impressed with service at GAMO so far.

as above.

Lite weight. Very easy to cock hammer spring. Universal Picatinny rail. Straight cylinder shroud for suppression experimentation. The In-line valve design seems to be slightly self adjusting on the valve opening time with feed back from the pressure pushing a projectile. Heavier Projectiles seem to balance pressure back on the valve so it stays open a little longer. Heavier projectiles do use more air but the power output tends to level out across various weights. Shooting an Air Bolt style projectile delivered over 200 foot pounds of energy and 490 feet second muzzle velocity. The 81.02 grain JSB Exact Pellet is very accurate out of this rifle. Round balls of 0.358' diameter are fast and accurate enough for game at closer ranges.

Ambidextrous safety, being left handed, the right side only safety is not convenient to access. This Picatinny rail might have worked OK on the Evanix Rex but with the big bottle on the butt end of the Gamo version, typical scope mounts won't cut it. I ended up fabricating 1 inch riser block from some scrap osage and bought 1.5 inch replacement screws to get optics up high enough I could get behind. Please change the Picatinny rail from the factory or supply precision visor blocks for the consumer to choose which works best for them. The trigger break is field expedient but a bit rough. An adjustable trigger would be wonderful.

Read "Things I would Change" above about the Picatinny rail, too low for standard optics mounts. I tried wood block "elevators" till I got two that worked to allow a scope to ZERO at 35 yards. Parallel mounting the rail, my scope could not adjust that low to get into the bull. I found that a front block 0.060" shorter than the back block worked well enough to get sighted in. Plan to replace wood blocks with aluminum blocks. After about 20 rounds shot from the gun right out of the box, I noticed a very small screw on the shorting bench. Turns out is was one of the tiny plate screws capturing the trigger group. Luckily I saw it. Lesson: Check all screw on your new out of the box rifle for tightness. Pistol grip screw was loose out of the box as well. Better yet. Pull all exposed screw and apply a thread lock compound before use! This thing is loud like a 22 powder burner. I have had several occasions early on that the trigger would not release when taken of safety but shot after cycling.

The gun came packed well. The tank cover is a snuggly fit plastic that doesn't feel cheap and will hold up well. The overall machining, IMHO, is on the heels of Air Force brand products. The gun is very light and shoulders well. For a .357 it's suprisingly quieter than my Condor .25. Grips are aftermarket adjustable so you can throw on your favorite Magpul.

Cocking lever has a bit of play when closed; though very strong, I'd prefer it not wiggle at all. For $999 it should come with some kind of dust cap. The carbon bottle screws into the guns frame and held more secure with a set-screw; mine's was missing, PA didn't have spares nor knew the dimesions. SURPRISINGLY! neither did Gamo when I called them, but they did give me the dimension of the screw that was readily found at Home Depot.

The barrel stops 8 inches from the unscrewable endcap. There isn't any baffling, so noise suppression takes place in this hollow portion of the shroud (DIY-ers have plenty of room to experiment with felt, mono-cores, etc for greater noise control). I mounted a Hawk Reflex dot sight for 35-40yrd applications and I'm very pleased with the gun's accuracy at this range. I'd be confident in saying the gun will do well at farther distances using a scope. I get 15 shots to a fill on full power (low power shot count claims are much higher but i dont intend to use that function).
