Whats the difference between this one and the r3

shadowninja31 (author)ThomasRex2010-09-13

You kinda have to look between the two, but the r3 has a different top to the gun and the system is a little different.

bumboozer (author)2010-07-19

Best gun ever I added a longer barrel, bipod, bayonet and made it shoot grenades and rods. I might post mods later

shadowninja31 (author)bumboozer2010-07-19

Cool. Send a pic please!

bumboozer (author)shadowninja312010-07-20

Same rate deal

Okay. Thanks!

Your welcome

Hiyadudez (author)2010-02-18

Very well done. 4.5*

But I see why it is 'medium-accurate'. It is because of your sights. They are supposed to be level, your back sight is higher than the front on, so you have to tilt the gun higher than your target, thus, decresing accuracy.

Lol. Good gun anyway!.                                        


shadowninja31 (author)Hiyadudez2010-02-18

That's not why. There is no real barrel except for the mag's walls. That's why.
Thanks anyways.
