That depends, what is it exactly?

Got a collection started last week, will post pics when I get home.

Id like to get my self an A1 style ar to put this on but I'm wondering how you Mount scopes on the carry handle, do you need a special one or some strange mounting hardware?

and does anyone have a recommendation for a good brand triangular handgaurds

I've got, like four bookmarks to places that make wooden stocks for the AR-15. I'll update sometimes today … I really like mine, but don't have a rifle-length barrel yet to put it on.

Bought a speed holster for my sig, but the thing was riding in a ball joint made of aluminium. Crumbled after the first day. At least I got my money back.

Goddamn I really want that. How rare are they? Export restrictions?

Got some yugoslav camo in the mail. Will post when they arrive.

>Export restrictions?

Probably ITAR if anything. I got in shit for bringing Gen III NV across the border once.

People think dimpling a barrel is bad because it disturbs the finish, so therefore nobody should ever do it.

Personally I just don't bother with it because set screws can have issues keeping the gas block in place, dimpling or no dimpling. Clamp-on, or better yet pinning the GB, are far more secure.

Nah, man the stuff I read talked about technical expertise needed to get the taper just right.

>Clamp-on

Hmm, so that hold it tighter than sinking a set screw into a dimple? I've got a barrel that keeps shaking all the screws loose, and I've had the block walk out on me once, rendering my rifle a single-shot.

I'd assumed, though, that clamp-on was even chintzier than a dimple/flat screw. But this uses, I think, pointy screws at each of the four corners.

Scroll down a bit and you'll see a clamp-on gas block being torque-tested after being fired for a bit. They applied enough torque to snap off the barrel pin and the gas block still showed no signs of movement. The thing about clamp-ons is that you've got a lot more surface area gripping the barrel–the gap between the barrel and the gas block is already paper thin before tightening, and once you've got the bolts locked down every square inch of the gas block is hugging the barrel and preventing movement. With set screws all of the retaining force is concentrated on the points of those set screws–and even if the net force is the same, the minimal contact area makes the set screw block much more prone to shifting.

Retarded backwoods hick science at its best, cheers for the link.

In any case, regardless of how much stock you put into this particular test, in general clamps are a better solution over set screws. You get better stress distribution, there's more force total holding the clamp-on in place, and you get a tighter gas seal. Pinning the gas block is obviously more secure than either, but also overkill.

What's the date of manufacture and did they give you anything indicating how many operational hours it had? AFAIK the PVS-4/PVS-502 have a MTTF of around 2,500 operation hours.

Should be fairly simple with the correct taper reamer. The reaming could be done by hand or machined, and wouldn't be much trouble. Just go down the taper and check the fit every few turns. Good reamers aren't cheap, but a cheap one would probably do alright for a one-off job if you can find one and make sure it is to spec.
