sorry noob question, don't want to be destroyed on the other forums.
My ar is really difficult to charge with one hand, i even put a gunfighter handle on it. now can the buffer spring have too much resistance or am i just being a girl? did a lot of looking too, couldn't find anything. |
How difficult is difficult? I have no issues charging my AR's, with or without a gunfighter CH in them. And by one handed, I'm assuming you mean on one side of the CH without putting fingers on both sides of the CH latch? That said, the buffer spring does offer a decent amount of resistance - sort of it's job in life

I don't honestly see any reason to charge it like that. I mean, when loading the first time, that seems impractical. When reloading, just hit the bolt catch. I doubt it's a problem with the gun. If you're worried, try a different AR and see if it feels the same. |

As I understand it, it's more about clearing malfunctions than initial charging - ie: being able to clear a FTF quickly or getting rid of a dud round without removing your trigger hand during a fight and keeping your control hand close to the mag release, etc. It's all for speed - same reason people like the B.A.D. levers. As Victor said, it could be your mag is exceedingly tight. Is it a new mag and if so what type? USGI's can sometimes be a bit tight fully loaded. Some people take a round or two out to decrease resistance. If it's a brand new USGI, simply loading and unloading it a few times should help a bit. If it's a Pmag, they are very slightly longer than a USGI to account for spring tension and should have no issues that cause it to be difficult to insert fully loaded, or dragging on the bolt when you try to charge the weapon. And yes, if you have access to another AR, cross compare the two and see if they're similar or not. If it's as difficult to charge as you're saying, then something is likely dragging on the bolt carrier. Do you maybe have a rifle length spring stuffed into a carbine stock? Wouldn't be the first time I've seen that happen. |

I just used my 5 rd mag and HSM ammo together for the first time and it was a dirty SOB to clear the round in the chamber. (heel on charging handle with muzzle pointed away, slam stock into ground) After playing with it, I found the mag feed lips allow every second round to stand up, almost producing a "stovepipe", but not quite, as it still chambers the round. I think the round standing up like that might have tweeked the case while feeding causing it to stick in the chamber. I can't confirm yet, because when I finally got the chamber to clear, as described above, the round flew into a bush and I was unable to locate it.
I've never had a problem with any of my 20ish Pmags with brass ammo. I have a feeling this mag is not quite right and is causing my problems. You may have a similar situation. I recommend trying different ammo and mags, you may find your rifle just doesn't like a certain round. |

ok, i got the complete dpms upper on ctd and the lower at the gunshow. I bought the lower from SOG Armory, its a dpms lower but had a sog stock on it, so with that im assuming they put it together using their own stuff. recently i got a cavalry arms stock that would not fit on the sog tube (both were confirmed commercial spec) and ended up getting a tube from cavalry, but kept the spring and buffer. I use 30rd pmags and its like that no matter how many rounds are in the mag. the upper is stock dpms besides the gunfighter charging handle. i'll have to go to the gunstore and try out an AR to see if its just me.
thanks for all the replies and help. |

If you take the upper off the lower, does the BCG slide freely? No hang ups or drag? Now, take the buffer and spring out of the tube and try dropping the buffer down the tube to check for binding. If you're all good to this point, reinstall the buffer and spring (have you put any lube in the buffer tube?). Now take a screwdriver (on anything you can find) and push the buffer down the tube, again checking for binding. Now, put the upper back on the lower, no mag, and cycle the action. Then put an empty mag in and cycle, then put one round in a mag and cycle, then half, then full.
As soon and it starts feeling hard to you, stop and figure what has changed since the last test, and inspect those things until you find your problem. One last question, everything has been cleaned and lubed, right? |

well I stopped by shooters vault just now, tried out one of their rifles and picked up a new buffer spring. I'll let you guess which ones which.
