I would suppose the M1911 is another modular gun which u can put together from bits n parts?

Yes. You can put together a 1911-pattern pistol in much the same fashion as you would an AR/M4 clone.Originally posted by HENG@:I would suppose the M1911 is another modular gun which u can put together from bits n parts?
However, almost all 1911 aftermarket components are deliberately manufactured slightly oversized and need to be trimmed and 'final fitted' by the builder. This gives the builder the option of assembling as 'tight' or 'loose' a 1911 as he desires.
'Tight' 1911s are built to extremely precise tolerances to maximize accuracy. However, they can be very finicky about the type of ammo that is used, and might jam if they are not fed the right ammo or kept fastidiously clean. 'Loose' 1911s, on the other hand, are built with reliablility in mind. They can be fed a wide range of ammo (e.g., round-nose, hollowpoints, truncated cones, semi-wadcutters, etc.) without jamming, and can continue to function even when they get dirty. However, the loose tolerances that enhance reliability result in degraded accuracy. -
ah I see. So a lathe would be an essential tool for a builder?Originally posted by Meia Gisborn:Yes. You can put together a 1911-pattern pistol in much the same fashion as you would an AR/M4 clone.

A lathe is certainly a desirable tool to have in any home workshop. Its usefulness extends beyond the realm of gunsmithing. Does your bathroom doorhinge still squeak even after being lubricated? No problem! Just yank the door hinge pin out, throw it on the lathe, mill its diameter down by 0.00001", and reinstall. Problem solved!Originally posted by HENG@:ah I see. So a lathe would be an essential tool for a builder?
For gunsmithing, however, model-specific jigs and fixtures are probably more important than a lathe. They are used to ensure that the proper angles on key fire-control components are not altered or milled to unsafe tolerances. Take this 1911 sear jig, for example:
1911 Sear Jig
It is used by many gunsmiths and builders to ensure that a proper sear/hammer contact angle is maintained when modifying the sear. If the correct angle is not maintained (say, by a novice builder who merely 'eyeballs' the angle when filing down the sear), there is a risk that the sear will not correctly engage the hammer hooks during live-fire, resulting in the pistol going full-auto until the magazine empties. Not fun, and certainly not safe! -
but whoooo! So u CAN modify a pistol to fire full auto.
dun need to buy a M93 no more. -
That's not the kind of full-auto capability you want in any firearm, lah!Originally posted by HENG@:but whoooo! So u CAN modify a pistol to fire full auto.

I've personally seen a 1911 go full-auto due to an incorrect hammer modification. It happened a few years back at the local indoor range. The entire 7-round mag emptied in under a second. The first round hit the target, but the subsequent 6 rounds hit the ceiling and took out a couple of light fixtures. Fortunately for the rest of us in the bay, the shooter had the presence of mind to hold on tight to the pistol and 'ride out' the burst. If he had gotten startled and let go of the gun, things might have turned out a little different...

This guy is a champion man... his keychain is truly a multipurpose tool.Originally posted by Meia Gisborn:DPMS sells a replica M203 grenade launcher (link here).
It's described as a "great conversation piece" and an "excellent wall hanger." Why anyone would buy one and install it in an otherwise fully functional AR15/M4 clone, is beyond me.
Perhaps this fellow can find a use for it:
he didn attach a toothbrush to it rite? -
This one more tactical

The AR's early reputation for unreliability during the Vietnam conflict was attributed mostly to the use of ammo that had too high of a calcium carbonate content in the propellant. The calcium carbonate would leave deposits in the gas system which, if not cleaned regularly, would lead to malfunctions. Unfortunately, US troops who were issued the AR back then weren't told about the importance of keeping the gas system clean.Originally posted by tvdog:For civilian use, the original M-16 gas system is probably good enough(?). Sure, it starts clogging up after a few dozen live rounds but a well-maintained civilian rifle should still be able to keep shooting with little danger of IA.
Unless you're with some militia training seven days in the bush in preparation for armageddon, I don't think you'd be looking at firing a 100 rounds a day. Would you?
Nowadays, the propellant used in ammo intended for the AR, both in civilian and military circles, have no calcium carbonate in them. Problems with the gas system clogging and causing malfunctions are pretty much history.
With clean powder, the AR's gas system is essentially self-cleaning and maintenance-free; I handload the cartridges for all of my ARs using either WC844 or H335 powder and have never ever experienced a gas system-related malfunction. In fact, I cannot recall ever experiencing any kind of jam or malfunction during the tens of thousands of rounds I've discharged through my ARs.
As for the number of rounds fired during a typical range visit, I'd say that I go through between 100 and 150 rounds per session. That number usually goes up during 'AR Nights' at the club, when it's not uncommon to burn through 200 rounds of ammo. -
So how many rounds can you put through an AR15/M16 before the fouling stops the operation of the rifle?
I was told between 6000 to 7000 rounds. Never got to try the theory.
Wonder why ZM-Weapons never caught on, first noticed them back in 2001. They've been around for quite some time offering a piston operated AR15, the LR300. I think Olympic arms also offer something similar.
The LR300 is a very good design in my opinion and it sounds like the solution some people were looking for. -
from the ejector port, I'd say thats a heavily modified AR15/M16/M4.Originally posted by Raptor937:This one more tactical

damn the stripped ar-15 sure looks familiar.
