A regulator is why a PCP can feel the same on the first shot and the thirtieth. Without one, a full tank shoots hot and the pellet slows as pressure falls. With one, the rifle meters air so speed stays steadier, which is what you want for a group on paper or a clean shot on a squirrel. The rifles below are PCPs in this budget, and most of them print a regulator in the specs. One of them never says the word, and that matters if a flat shot string is why you are shopping.
What the regulator is actually doing
A regulator holds valve pressure at a set point, so the pellet does not start fast and then fade as the tank drops. That steadiness is the feature. It is not a power booster. Energy still comes from caliber, pellet weight, and how the rifle is tuned. Where the listing prints energy, the Air Venturi Alpha quotes 36 FPE, the Hatsan Flash-R QE quotes 40 FPE, and the Benjamin Marauder Gen 3 quotes 80 FPE. The Umarex Notos quotes 700 fps and no energy figure at all, so do not treat that velocity line as if it were the same kind of number.
Which caliber you actually want
.177, which is what the JTS Airacuda Max velocity line claims, is the flat-shooting, cheap-pellet choice for paper and small pests. .22, on the Alpha, the Notos, and the SIG’s pellet magazine, is the middle ground most backyard hunters already know. .25, on the AirStryke, the Flash-R, and the Marauder, is the heavier pellet and the higher printed energy. Match the caliber to the animal and the distance, then buy pellets in that caliber only. A rifle and a tin that do not match is a very handsome club.
Air, fills, and the pump
Every rifle here is a PCP, so it is a paperweight until you can fill it. Read the max pressure before you buy a pump or a compressor. The Alpha lists a maximum fill of 3,625 PSI (250 BAR). The Marauder Gen 3 lists 3625 PSI (250 BAR). The AirStryke’s maximum safe pressure is 3000 PSI. The Flash-R fills to 250 BAR and runs its regulator at 125-130 BAR. Cylinder size is the other half: 118cc on the Alpha, 215cc on the Flash-R, 0.35L/350cc on the AirStryke, and 500cc on the Marauder. Smaller is easier to carry and empties sooner. The Notos, the Airacuda, and the SIG do not print a fill pressure or a cylinder volume, so read the manual before you hook up a pump.

Best Regulated PCP Air Rifles Under $800
1. JTS Airacuda Max .177 Cal
This is the wood-stock pick when you want a .177 for paper and pests, and a trigger you can set light. JTS quotes up to 1000 FPS with .177 pellets, a regulated action, a side lever for follow-up shots, and a two-stage trigger you can bring down to 2 lbs, plus a Picatinny rail so you can mount a scope.
Listed weight is 9.1 pounds, so this is a full rifle you will feel after an hour on your feet. The size field says .22 and .25 while the title and the velocity line say .177, so confirm the caliber on the order page before you buy.
Best for: Wood-stock .177 shooting with a light trigger
Listed at $439.99 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
2. Air Venturi Alpha Compact .22
Start here if you want a short .22 rather than a full-length hunting rifle. Air Venturi calls it a regulated sidelever PCP, with a 12.2 inch barrel and a 33.5 inch overall length, which is the truck-cab size on this page.
The 118cc cylinder fills to 3,625 PSI (250 BAR). Air Venturi quotes 900 FPS with 11.75 grain pellets and 36 FPE with 25.4 grain ammo, and you get two 10-round magazines. That small tube is the trade: the rifle carries easily, and you will be back at the pump sooner than with a 350cc or 500cc gun.
Best for: Compact .22 that fits in a truck
Listed at $283.57 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy.
3. JTS AirStryke Magnum .25
This is the .25 for small game when you also want a threaded muzzle for a moderator. JTS quotes up to 1050 FPS with 20.04 grain .25 pellets, a 23 inch rifled barrel, and an overall length of 40 to 42 inches, with an AR-style grip, a synthetic stock, and a rubber buttpad.
The regulated cylinder is listed at 0.35L/350cc, with a gauge, a Picatinny rail, and two magazines in the package. The barrel is 1/2 UNF, so a common moderator will thread on. Do not fill it past the listed maximum safe pressure of 3000 PSI, which is lower than the 3,625 PSI fill on the Alpha and the 3625 PSI fill on the Marauder.
Best for: .25 power with a threaded muzzle
Listed at $349.99 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
4. Umarex Notos Carbine .22
This is the carbine for small game and backyard plinking when the rifle has to stay light. Umarex quotes 700 fps with a 12 grain .22 pellet from an 11.75 inch barrel, a regulated fixed tank, and a side lever with a 7-shot auto-indexing magazine.
The listing puts the weight at 5 pounds, the light number here, and calls it out for small game, plinking, and target shooting. The size line’s other inch figures look like a carton, so judge fit from that barrel length and the 5 pound weight.
Best for: Light .22 carbine for small game
Listed at $264.95 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy.
5. Sig Sauer MCX Virtus PCP
This is the semi-auto for target practice when you want an MCX-style rifle with sights already fitted. SIG quotes a 17.5 inch barrel, flip-up front and rear sights, an M1913 rail, a synthetic stock, a 37.5 inch length, and a 7.5 pound weight, and it feeds from a 30rd rapid pellet magazine.
SIG says it doubles the muzzle energy of classic CO2 air rifles and wants premium pellets for better results. The listing calls the caliber .22LR and never says the rifle is regulated, so treat it as a pellet trainer, not a regulated hunting PCP, and do not feed it firearm ammunition.
Best for: Semi-auto MCX-style target practice
Listed at $339.99 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy.
6. Hatsan Flash-R QE .25
This is the shrouded .25 if you want quieter shots, a match-style trigger, and pellets plus targets already in the box. You get the Hatsan Flash-R QE, a side lever, two rotary magazines, a QuietEnergy shroud with an integrated moderator, and the Quattro two-stage adjustable trigger, on a synthetic stock.
Hatsan regulates it at 125-130 BAR. The fixed 215cc cylinder fills to 250 BAR, and the spec line quotes 900 FPS and 40 FPE. Listed weight is 7.5 pounds. A built-in gauge and a quick-fill nozzle are included, so the first fill does not start with a parts hunt.
Best for: Shrouded .25 with pellets in the box
Listed at $319.99 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.
7. Benjamin Marauder Gen 3 .25
This is the rifle for stretching a .25, with a regulator you can adjust instead of a fixed setting. Benjamin quotes up to 1150 fps and up to 80 fpe from a regulated bolt-action .25, and points that power at small game and longer shots.
The 500cc reservoir fills to 3625 PSI (250 BAR). Integrated suppression, an all-weather stock, and an adjustable cheek piece are on the feature list, along with a 15 lb cocking effort and a listed weight of 9.4 pounds. Bring fill gear that can reach 3625 PSI, or you never use the top of that tank.
Best for: Adjustable regulator and the most printed energy
Listed at $787.80 when this guide was last updated. Amazon pricing moves, so check the figure on the page before you buy. Amazon is showing limited quantities on this one.

Frequently Asked Questions
Will a hand pump fill these?
Yes, if the pump can reach the pressure that rifle lists. A 3,625 PSI fill on the Alpha, or 3625 PSI into the Marauder’s 500cc tank, is a long session on a hand pump. Do not buy the rifle and assume the pump you already own is rated high enough. Match the pump’s max to the rifle’s max first.
Does regulated mean more power or longer range?
It means speed stays steadier, which helps you hold a zero. It does not add power on its own. Distance still follows caliber, pellet, and the energy the maker quotes. The Marauder is the one that quotes 80 fpe and talks about longer shots. A regulated .177 is still a .177.
Why does one listing say .22LR?
The Sig Sauer MCX Virtus listing says .22LR and also calls it a pellet air rifle with a 30rd pellet magazine. Buy .22 pellets for it. It is not a centerfire rifle, and the features never say it is regulated.
What if the rifle has no sights listed?
The Airacuda and the AirStryke list a Picatinny rail, and the SIG lists an M1913 rail plus flip-up sights, so you can shoot the SIG before a scope arrives. If the features do not mention sights, plan on glass or another aim point before you expect to hunt with it.
Pick the job first, then the fill your pump can actually make. For the most printed .25 energy and an adjustable regulator, take the Benjamin Marauder Gen 3 and fill to 3625 PSI. For a short, light .22, take the Umarex Notos at 5 pounds or the Air Venturi Alpha at 33.5 inches with two 10-round magazines. For a .25 you can hang a moderator on, take the JTS AirStryke Magnum and stop at 3000 PSI. For a shrouded .25 that quotes 40 FPE and a regulator at 125-130 BAR, take the Hatsan Flash-R QE. For a wood stock and a 2 lb trigger, take the JTS Airacuda Max in the caliber the velocity line states, which is .177. Use the Sig Sauer MCX Virtus when you want semi-auto practice with a 30rd rapid pellet magazine, not when you need a printed regulator.
