    *AR-15 lowers can come with different pin sizes. Most have pins that are .250" in diameter. That's what the Crosman MAR177 fits.

    Additional 10rd mags can be purchased, as can a single-shot tray. The mag and single-shot tray made for the Benjamin Marauder air rifle also fit the MAR177. Both items are shown in the accessory links for this air gun.

    Crosman's MAR177 is an AR-15 upper and attaches to an AR-15 lower. The lower is a firearm. The upper shown on this page is an airgun. Putting an airgun upper on a firearm lower does not make the entire unit an airgun. It's still a firearm in the eyes of the law. Do not shoot this in areas and locales that do not allow discharging a firearm, as you may be cited for violating the law.

    If you've ever wished that your AR-15 could save you some bucks and use airgun ammo, your wish has come true!

    The PCP conversion kit is an upper that fits your AR-15 lower and converts it from powder to air. Fill the onboard reservoir with high-pressure air from a pump, scuba tank or carbon fiber tank.

    The choked, free-floating Lothar Walther barrel is considered the cream of the crop, and it'll deliver match-grade accuracy. In fact, this conversion kit is designed to let you compete! You can have a cool-looking gun without giving up anything in the accuracy department.

    This system is easy to attach to your AR-15 lower. Enjoy more shooting with less noise. Think of all the money you'll save by switching from expensive centerfire ammo to lead pellets!

    Things I liked:Fits great on my 15 lower. Very accurate with my red dot or scope. Functions very well. Easy to pump up to 2000 PSI with the Benjamin hand pump.
    Things I would have changed:Lighten up the over all weight.
    What others should know:The standard sights are not up to snuff. Should be replaced.

    Things I liked:The MAR177 fits well on my Yankee Hill lower. I had already made some mods to the Yankee Hill lower (buttstock and trigger) so it was nice to be able to take advantage of those changes. Removed the iron sights and replaced with a 4X combat scope - Shooting indoors on a 10M range this combination has proved extremely accurate. The MAR177 upper is a well made, expensive piece of machinery. Highly recommended for anyone wanting to stay on top of their AR skills.
    Things I would have changed:A friendlier price point.

    Things I liked:Compatible with my Rock River Arms LAR-15 NM A4. One thing I have do do differently from the real upper is that the trigger mechanism's hammer has to be pushed down and locked in place when mounting or dismounting this MAR177. Unlike many air guns, there is no need for a separate dry firing mechanism. Documentation states that one way to remove air from the tank is by firing repeatedly, without loading any pellets. It's very accurate. With a competent shooter, and if not constrained by the 4.5 lb. service rifle trigger pull minimum, this could be competitive even in a match air rifle competition (may not win, but at least be competitive). The capabilities allow me to practice far more often than if I had to plan a trip to the range.
    Things I would have changed:The price should've been lower, although I understand the reasons behind the pricing: the limited market on one hand, and the limited buyer choices on the other. It's not a "cheap" item and I've had shooters look at it up close and remark on its quality. It has already saved me several expensive trips to the range.
    What others should know:I bought a Hill Pump and it took only 145 pumps to fill the tank from empty to full. I also had to get an adapter for the pump. Subsequent topping off only takes about 50 pumps from the Hill pump. I briefly tried non-toxic, high quality (supposedly) pellets for indoor use but the results were abysmal. I switched to RWS Meisterkugeln 8.2 grains and got vastly improved groupings, but I now practice outdoors.

    • Harold from USA asked:

      Can you tell me what size air tank it has?

      • John from Canada:

        Dimensions are 18inches long and about 5/8 internal diameter: about 22 cubic inches volume. Takes about 125 pumps of the Benjamin PY-A-2222 pump for 2800psi.

    To fill your PCP gun:
    1. Pick a source of air shown at right
    2. If an adapter is needed, one will be shown
    3. Add both to your cart to get hooked up
