Question about weapon assembly? Topic: Best-case scenarios
June 20, 2019 / By Hudde
Question: During weapons training in basic training,we were informed about the dangers of reassembling a weapon incorrectly particularly the trigger assembly. I know how to reassemble a weapon but I forgot what can happen if you do it wrong. I thought so. I know it won't fire without the firing pin, I figured it would explode but I wasn't sure.

Worst case scenario is a catastrophic malfunction leading to the weapon exploding and rendering you with serious injuries or death. Best case scenario, it doesn't work.

I don't have any assembly code for the PIC18 written for this, nor do I know where to point you. But you only need the least significant four bits (0-15), so if you find one that can generate 8-bit values all you'd have to do is mask off the upper four to get your exact range. There are two basic kinds of very simple RNGs that are readily written in assembly code on a PIC18, though. They are called "linear congruential" and "xor shift" or LFSR (linear feedback shift register) methods. Either would probably do fine for you. The linear congruential types are of the form, x= m*x+b, and you have to find an appropriate m and b. Plus, you need to multiply. Luckily, the PIC18 has such an instruction. So it shouldn't be too hard to write the code. It's just a matter of picking good m and b values -- primes usually work okay, though. Just make m big enough to cause the low order bits to shuffle up well. The value 'x' will be some static value you probably keep on the base page for convenience (page 0.) It's value needs to be initialized at startup to something fixed or random (if you have a source for that.) The xorshift method is more for micros without a multiplication instruction. The code could look like: unsigned char xorshift() {     static unsigned char x= 1, y= 1;     unsigned char t= x ^ (x<<5);         x=y;     return y= (y^(y>>1)) ^ (t^(t>>3)); } Note the values of 5, 3, and 1 used for the right shift and left shift operations in the code. There are different combinations of these that all work out well. I just picked one of the sets, but there are papers written that discuss good groups of these three values. The rest of the code remains the same, though. If you can translate that into assembly for your circumstances (you will need two static values for this to hold the above 'x' and 'y' values and retain them, call to call), then you could go this route as well. Note that the (x<<5) operation, for example, could be implemented using a SWAPF to move the initial 4 bits and then one of the rotate instructions to get the 5th shift done. You'd need to mask off some bits to complete it. So something like 3 instructions to do the job just for that part of it. Anyway, that's what I'd do in your circumstance -- either find assembly code or write it after doing some reading and deciding. Try the following link to start:

One of the worst problems would be if the mis-assembled gun doesn't cock on closing the bolt. Then you get a 'slam fire' where the cartridge goes off in an unlocked chamber. This can ruin your whole day and then some.

What can happen if you do it wrong? Oh I remember the first time I went shooting with my brother. He took apart the M9 and he misplaced something, I can't recall what it was but the cock (the top part that houses the chamber) flew off and the remaining barrel of the pistol exploded. Luckily, his hands were barely burned and he only went to the hospital for first degree burns. Just read the manual and you should be fine, like I am :)

A question goes to voting if you have not chosen a best answer after 4 days....Then you can vote for best answer and receive one point but there is no guarantee that the one you think is best will be chosen as the answer with the most votes will get best answer.... You can also vote no best answer (no points given) and if that is the question with the most votes it is removed and the posters 5 points are returned.....Any level can choose best answer for a question they have asked and any level can vote on any questions in voting.
