Radiusing and polishing the back of the bolt makes a 1022 run better with lighter ammo most of the time. It gives the bolt better leverage cocking the hammer.

I wonder how different the velocity might be between the long and short barrel? Even thou they all are subsonic it seems that a higher velocity, if obtained by the longer barrel, would be louder but on the other hand shorter barrels always seem louder to the ear I guess due to still burning powder o...

Sorry if this has been answered before didn't find it in a search. I've had different answers to this, some say a 01 FFL gunsmith can repair machine guns and so by the same rule can repair suppressors. Others say no only a 07. Who is correct?

I don't post much so please excuse me for jumping into a technical thread without much introduction. I'm new to suppressor design but have done a lot of work with compensators and flash hiders. I had the thought that if the goal is to direct as much gas as possible into the reflex portion then porti...

I would save for a Grizzly gunsmith lathe. I had an old South Bend that I still love but the Grizzly is just a whole nother world and will do everything I could ever want including metric threads.

I just buy a 1/4 inch nylon bolt from Home Depot long enough to cut a piece out of the unthreaded section to make the buffer. Cheap and very effective. No need for drilling holes or adding steel.

Officers ACP's come with a bull barrel although they do have a small thin bushing from the factory to avoid the Detonics patent. Replacement OACP barrels can be bought that do away with that fragile bushing and I highly recommend going that way. Actually the shorter 1911 versions at least in 45 make...

The Saiga's typically do not function reliably out of the box, they are popular with certain competition shooters where the drum magazines give it a capacity advantage but they spend a lot of money and effort to get them reliable. A decent 1100 will be reliable out of the box with cheap parts availa...

It will work that way but if you plan on shooting many magnums you might buy the magnum action bar sleave as it is heavier than the 2 3\4 version to soak up some of the extra umph. It will also work fine with regular 2 3\4 shells too. The 3 inch barrels not only have the longer chamber but also one ...

Looks like a great idea. How large are the ports? Just a thought that you wouldn't want them to be large enough for one of the plastic wad petals to catch in it and possibly lodge a piece or even the whole wad in the suppressor with disasterous results when the next round is fired. I have actually s...

Not to be argumentive but I said nothing about the Browning locking system. Just because a pistol does not use the Browning system doesn't automaticaly make it a fixed barrel. A good example are the Hi Points for instance, they actually have fixed barrels and are built in the popular centerfire pist...

Since $200 was a whole lot more money in 1935 ever wonder why the tax has never increased?

Why worry about over-penetration when at best only 30% of rounds fired by the police actually hit the intended target?

If we could just get a chance to reverse engineer an alien suppressor.

Somebody said co-witness..yes I want the most cluttered up sight picture when I try to aim thru my red dot or scope. I think I hate that more than rails from butt stock to muzzle but when I first saw a rail section on a butt stock I thought the apocalypse had to be close. There is hope as stated, th...

The M9 is considered a fixed barrel?

If you need to take a quick poop out in a field you better make sure of what is around. http://youtu.be/qRm8okHhapU

I couldn't believe it when I saw that collostomy thing, that big hunk goes back and forth when you're not locked? What a genius idea.

I can't rationalize not ripping this guy. His body language the words he used no matter how it was edited, he is at least an idiot if not a douche bag FUDD with a Rolex who owns a gunstore but has no idea what the 2nd Amd is about, or probably the Constitution except for making himself money. A used...

Just grab a YHM stripped upper..(well has the dust cover and forward assist) and a Micro Gas block from Midwest Industries with a CMMG barrel as well as a Model 1 handguard and toss it together and your good to go.. My Blk is the one in front.. http://i824.photobucket.com/albums/zz163/Chondro2009/3...

A couple of comments and possible issues. If any part serialized or not is considered a suppressor, a baffle for instance, why is the front tube not in the same situation as a baffle? Is it possible the governing body is distracted with other issues right now and ok'd something they may change their...

Dies are good for chasing threads not cutting them.

Very cool.

A 2mm flare must be similar to an 80 year old's ejaculation.
