    Absolutely & as a matter of fact! You SHOULD store it pressurized!


    It’s my favorite pcp.

    redriverhunter -- The Benjamin Discovery appears to be a great PCP rifle -- hopefully, a great choice for you! PCP firearms SHOULD be left filled up for storage. My "need" for one was fulfilled when an Air Arms S200 (factory refurb/return) came up at Pyramid Air, and to say I've been more than pleased with my selection would be an understatement. The AA may be filled to 2.7K, albeit I don't go above 2.5K, from which I get about forty-five great shots, before point of aim and velocity start to suffer. The AA has a lower advertised muzzle velocity than the Benjamin -- 800fps versus Benjamin's 900fps. An advantage to the Benjamin is it MAY be converted to CO2 use -- I can tell you pumping a hand pump (I have a Hill) quickly stops being fun . One of the main attractions for me was the available and readily switched air tanks for the AA -- In the field/hunting I generally go out with the attached tank filled, and a spare in my pack.
    BEST wishes -- either's a great air rifle! I reckoned I'd offer my experience with the Czechoslovakian (Brno) made AA, in case you'd wish to take a gander at it.

    My Marauder stays pressured all the time, so handy for making a quick shot.
    Unlike C-02, always empty unless just filled.

    I store my Benjamin with 2 pumps.
    A few days before I went overseas for a year, I pumped it twice, fired it, the pumped it 2 times again.

    When I got back, I cocked the bolt and fired it,
    Pumped it twice, fired it again, all shots sounded the same.

    Everyone can learn from their mistakes.
    However; it's less painful, and cheaper to learn from the mistakes of others.

    Old age and treachery will always overcome youth, and skill.

    OK folks. Enough of this idle chit chat. This ain't no retirement home.
    EVERYONE!!

    Yup Pneumatics too should be stored with a few pumps in them.

    What about break barrels? Should they be cocked and set aside for storage?

    Sparky45 -- Most all shooters I know, with break barrels, store them NOT cocked, but with the barrel barely broken so the breech seal isn't compressed while in storage. Said seal is and should be slightly rounded in looks -- when it gets "flat" it is a sign it's (quite an easy task for most) due for replacement.

    I agree with George

    NO do not store springers cocked. Further to that fact even hunting with them all day for instance will often show a decrease if power from leaving cocked all day. (But generally come “back”. NITRO, guns are different.

    The reason to leave charges is for seals. The reason springers DONT is because it fatigues the spring.

    GTA website has a wealth of information on non firearms.

    I like my 22cal discovery rifle used to shoot it a lot, it's loud enough that the neighbors will complain. This is the reason I dont shoot it anymore.
    There are also a lot of mods and after market parts for the discovery which is nice.

    Mine has:
    Anti hammer bounce device / power adjuster
    Improved valve flow
    The bolt nose has been removed and replaced with a drill bit.
    Anti bolt handle flip device
    Double barrel bands
    Enlarged transfer port in barrel
    1/4 tubing transfer port
    Upgraded o-rings

    Ramson222 -- "Moderators" are legal to have on airguns. A fellow at range has one on his air rifle, complemented with a "de-pinger, and it is scary-quiet. If you have interest in a moderator so neighbors may no longer hear it -- as well as a few other "mods" -- check out Hill Air, https://hillairgun.com .

    I store my Discovery at around 1200 psi. I believe that is what the manufacturer recommends.
    It has keep that pressure for about a year.

    IIRC the only airgun suppressors that are not legal everywhere are the detachable metal tube ones over. Those might be removed and adapted to a firearm.
    The synthetic tubed versions aren't strong enough to withstand fire arms muzzle blast, or so its said.
    Fact is PVC tubing has been used on rifles up to .308 so I would not doubt that even the carbon fiber suppressors could be adapted for limited use with a bit of work.

    The suppressors that are an integral part of the barrel seem to be legal everywhere.
    I have heard of some cutting away the suppressed section of barrel hoping to improve accuracy. I think if one did the removed section might be illegal to own.

    I just recently bought a Benjamin Discovery Rifle and Pump which I bought with Fluke 87V Multimeter on amazon and what I can say is it has nice quality and lightweight. Fairly accurate for a low end rifle. Easy to use but the hand pump takes some work. You only get 16-18 useable shots per fill.

    Congrats on your Discovery -- fine air rifle! When I purchased my 1st PCP, I also went for a pump. The sales person advised the Hill over Benjamin, but, they are both good pumps. I was told that there are three chambers in these, and the air moving from #2 to #3 is really kind of slow. Hence, salesman advised at BOTH ends of stroke -- the very top as well as the bottom -- to pause/hold the handle there for a bit of time. He suggested preceding the word, "Mississippi" with the stroke number -- e.g., one-Mississippi, two-Mississippi.... until you attain desired pressure. While it is admittedly a work-out from zero pounds -- an MT cylinder -- I generally "use" roughly 1,000 psi from my max fill pressure to refill, with my generally getting ~35 usable shots. Try the pause at each stroke end... it surely helped in my pumping.
    BEST!
