Is a PDI hop up chamber really worth it?

I could understand why thatmight be so but im just scared about drilling into the outer barrel. Lol i have little handy-man experience but i may try it eventually

I guess i'll try the TDC mod when i have the time then. But one thing i was wondering was what kind of bucking does the Jav/Snow Wolf M24 accept? Last night I modified a systema bucking (AEG) to fit the chamber (accepts APS2 barrels so I'm guessing APS2 bucking?) but I have yet to test out it's consistency.

Again, i do not have the tools/experience to file down an rhop evenly. I feel as though i might just screw them up by failing on a file-job):

If I remember correctly, I should be using atleast a 400 grit sandpaper right?

On that note, I should probably order my replacement barrel and do the Rhop on that instead of on the stock barrel huh? I am willing to do the TDC mod, just gotta find the time and take a trip to Home Depot to get some 400 grit sandpaper. For now i'm just trying to familiarize myself with the whole process&steps to get it right so that when the time comes I wont be sitting there on ny butt wondering what to do next. Lol

I could install it on the stock but i was thinking that if i upgrade my barrel, there may (or may not) be a small difference in the window although it is still an APS2 cut. Maybe i'm just being paranoid though. Lol and also, when i was cleaning/inspecting my barrel, i did see one or two sort of like "cuts" or deep scratches in the barrel, which further leads me to believe i did not receive a new unit. I am willing to try the polish and see if it changes anything but i do plan on replacing the barrel in the future.

A quick google search brought me to this http://m.homedepot.com/Paint-Paint-...splay?catalogId=10053&langId=-1&storeId=10051

Seems that my home depot does have it in stock so i might drop by today!

Yeah, I know that it wouldn't be perfect but i received the gun in a beat up opened box with some stock scratches, a broken mag, and the "messy" barrel but i didnt wanna go through the hassel of sending back the gun since it was firing and i could work with what was given. But back to topic, i think i might try to do the TDC mod when i get home today actually... Haha

It is APS2 in a sort of VSR10 body. It accepts APS2 barrels, but has the adjustment arm of a VSR10.

Yeah, true on the first two points. I was debating on ordering the PDI chamber which is why i wanted to know if it was worth it through this thread. I have read of people getting the M24 PDI chamber and having to custom fit it to the Jav/SW M24 as they are in fact the same gun. And the custom fitting didnt go well on the accounts i have read about

Silentball, Do you have an R hop in addition to those upgrades?

Also, I am still unable to find a bucking for the SW M24 besides the Falcon bucking specific for the M24,.

I guess I'll follow in your footsteps for now then. TDC for now.

I just did a garage scavenge and found "Mothers Mag&Aluminum Polish" and "Turtle Wax Rubbing Compound." Will these suffice for a barrel polish?:O

I just did the polish and it actually looks good inside, but I'm just a noob and it could just be psychological But the Mother's Mag&Aluminum says "Not recommended for gold plating, chrome, anodized, painted, or coated metals." Not sure where the stock barrel fulls into besides a brass barrel.?

It also says "If black residue does not appear, STOP, it is not a polishable metal." - My barrel had tons of black residue (lol) so I'm assuming I'm okay?

Also, I just found a set of "Nicholson Round Handle Needle Files" although I do not know how fine these files are (they do look pretty fine, but I have little experience with files and all that)

Sorry to double post, but I did the mod last night. Should I put a material like an eraser on the end of the screw to help cushion it, since it's metal on plastic (arm)? My set up currently is a hex nut, washer, spring, and an M4 hex screw. I will be jb welding the nut to the barrel tomorrow.
