    "The XM177 has always been one of my favorite AR type rifles.

    This gun has great build quality with no front end wobble and a very acceptable amount of play in the stock.

    It shoots hard, has a great kick, and has been reliable for me, although I am only a target shooter

    The 20 round magazine is/was leak free. This gun also works with the 30 round magazines with no problems.

    The gun is very easy to service and clean

    I would VERY SERIOUSLY recommend--BEFORE TAKING YOUR FIRST SHOT--to add some shims to the bolt catch so that it has no side to side play, but still pivots freely. Also, grind down the bolt catch so that it has greater travel. While the bolt catch is out, apply some JB weld or similar material to the area where the little lifter in the magazine makes contact--about a millimeter or so. Search google/youtube for easy directions on these mods. These mods will not only make the bolt catch work more reliably, but it will extend its life.

    The gun comes with a barrel wrench.

    "Let start by saying I am a big fan of Vietnam era weapons so when I laid eyes on this I squealed with delight in the splendor of how close in detail this is to an actual XM177. The recoil is solid(not real steel .223/ 5.56 solid but still a joy). I have owned this gun over a years time and it still shoots like a dream (I target practice in the backyard often, no wargames yet). The construction is very solid minus my model having a very slight bit of wobble between receivers(don't know if they all have it) but it feels stable and has lasted through a couple drops on a stone floor and a came back swinging. If you are a Vietnam era fan or just want a solid realism out of your airsoft gun I highly recommend this. 5 out of 5 all the way!

    Solid metal construction
    20 rnd mag for realism
    Blowback and felt recoil
    Accurate at med-close ranges

    20 rnd mag(lowcap)
    30 rnd mags do not feed in this properly(at least not in mine)

    "This is definitely a good purchase. As I have shot the real M16 (not an AR15) I can tell you the recoil is almost identical. Out of the box the gun is lighter then I expected, as i forgot how small they are, but it is true to the real XM177 E2. I received it today and have already put almost 500 rounds through it without any issues using Matrix .30's what so ever. It is amazingly accurate (as it has an M4 length inner barrel) and anyone could easily use this in the field without getting fatigued. Even though it was a little bit colder (about 50-60) it functioned flawlessly even on full auto. I highly recommend extra magazines because this GBBR has an amazing rate of fire. Definitely five stars in my book.
