Well, there is some. If the upper and lower aren't consistently aligned, since your cheekweld is on the lower and your sight picture is through the upper, accuracy can suffer. Which is why Service Rifle shooters use Accuwedges, the JP threaded takedown pins, or something to hold the two halves in consistent alignment.

I'll post pics when I decide.

The benefits of having a "pre-ban" rifle went out the window in September of 2004, unless you live in one of those God forsaken areas that still denies their citizens the option of being free.

Keep your Bushy, anything you might replace it with is most likely from the same exact forge. If you want a flat-top then scoot over to Core 15 and pick up one of theirs for low dough.

Okay, I see your point, but as a practical matter the amount of play between a fairly loose upper/lower as it might remotely affect cheek-weld would be about 1/4 of a millimeter! I think that guys use Accuwedges and JP takedown pins to make themselves feel better, if the gun feels solid rather than rattles a little it makes them think it might shoot better. I don't believe those things make a whit of difference, except that they make money for Accuwedge and John Paul.

Having said that, I have a JP takedown pin on one of my ARs!

In '93 or so a friend talked me into buying a Bushmaster AR15 kit and assembling it. It was a great, no frills rifle.

Flash forward (feeling kind of old here) eighteen years. After a long family-related hiatus from guns, I have dived back into it... My no frills carbine (It has a carry handle. How embarassing is that?) with a 1/9 barrel is like a Model T! Plus the once renowned Bushmaster name has become known for garbage /budget guns.

Here are some options I would appreciate input on:

1. Sell it (I think a pre-ban is worth around six or seven hundred) and buy a Spikes or PSA 14 inch with a pinned flashhider, flat top and mid length gas system.

2. Just get a new upper like what I described above and live with a mismatched rifle. Bushmaster and.,.

3. Forget the new stuff and enjoy my classic rifle. The new ones will always be available.

Thanks for your input. I can't promise I'll follow it but I hope to find something insightful.

Is there anything wrong with it? If not then I'd keep it. A carry handle upper isn't really an issue and are coming back.. If you don't like the A2 stock you can replace it. The only other thing is the lack of a muzzle device. You'd have to get the barrel threaded or replaced if you wanted one. Otherwise, just leave it. You can always buy an additional complete upper or just a barrel and upper receiver, if you want to invest in all the tools. I'd consider buying a complete upper though. http://palmettostatearmory.com/ does have some good deals. But I'd check LMT and BCM as well.

By the way, I caught the newest episode of 'American Guns' last night (after visiting their shop last week). The part about building a Yellow Boy was pretty interesting but the bimbos shooting with the local firemen was really dumb. I guess I have to visit the shop again and give the guys some advice on how to make the show better for an intellectual audience like us guys.

Hear Hear! 99.9% of most accuracy problems or inaccuracy from a gun are caused by that loose nut on the stock. A good solid position, good sight picture and trigger squeeze are worth 3 clicks of windage any day.

Where's a good place for AR parts? I need a pivot pin spring.

I like MidwayUSA and have ordered some really small AR parts from them.

[El Guero]

Been reading a little bit about the .327 Fed Magnum this morning and I think I might want one. Anybody have one? I am hoping they release the SP101 with the 4" barrel in .327, might be perfect for my wife and not so expensive to reload for either.

Next is bobbing the frame, Kev!

In addition to Midway, Brownells carries just about everything you could ever need or want. It's where most professional gunsmiths get theirs.

It can be so loose a goose could fly through there and still shoot if the trigger is decent. Only thing that needs to be done to make an accurate AR is float a good barrel and have a decent trigger, period, end-of-story. All else is window-dressing.

It is pretty annoying to have a loose upper lower fit. Your cheek weld is on the stock, which is attached to the lower, and your sights are on the upper, if its loose your sight picture can cange a bit, not huge, but it annoys me. Some might not find it a problem.

Definitely somthing that can be fixed if it is bothersome

Thanks guys, I found them on Brownell's site, is there a little piece
that goes in the end of the spring that fits in the slot on the takedown
pin? OK, never mind, watched the video and figgered it out.

It's called detent. It's those two shiny pins at the upper left. They tend to go shooting off if you're not careful.
