MagPul PTS MASADA ACR

Nikon had the right idea. I put a madbull bucking on and I could tell the actual nub wasn't getting good contact, by cutting about a millimeter off the end the rubber fit farther onto the barrel.

Hmmm. I was actually thinking the "adding a strip to the top..." gave the nub a thicker part of the bucking in the area of contact therefore giving it more to push down on. So all you did was cut off a millimeter toward the front of the barrel and the nub worked better?

I was wondering what guys are using for springs? I took the stock spring out and noticed it is much smaller than the stock Madbull 120 spring. Are people just cutting springs down? Or using a specific spring?

 

Thanks

PDI W Hold bucking now in stock at ASGI, go get one guys. You will not be disappointed.

 

They increased the accuracy in my masada at 170 feet from like 3-4 foot spread to about 7 inches, not to mention my hop needed to use a .25 went from all the way and needing more to about 1/3 on all the way.

Fixed the micro switch and power issue, power was a worn piston head oring, and microswitch worked again after re-assembely.

 

You didn't happen to snap any photos of the micro switch did you ?

Wondering if it's just a common type that can be replaced easily, for that day when it comes.

Have you noticed there's a quite big spacer/weight inside piston.

 

I removed that, cause I replaced the piston head (using head with bearing by Modify)

 

Btw, has anyone tried to replace cylinder head? I was thinking to try G36C/AUG head... there's not much difference in length (I'm also using Wii Tech nozzle)

pretty sure it's proprietary.

 

 

 

On another note, has anyone had any problems fitting aftermarket gears or pistons?

I got a super shooter azimuth clone with 7 metal teeth and riotsc revolution gen.2 version 2 gears and apparently they aren't wanting to go, needing modification.

Here you go. I was having trouble after adding a AWS Sentry. The problem wasn't the Sentry, but likely the micro switch or more specifically my crappy soldering job on the switch contacts which I corrected.

 

Found this part on Digikey. The rating isn't quite as high, but looks like it would work.

I also noticed a little nick in one of the signal wires. I added a little shrink wrap around the wire there to reinforce. Seems to be firing well now. Also added a different piston and piston head. Much quieter now.

 

Note this was an upgrade on my part. Stock the AEG fired fine.

I'm going to use this kind of cylinder head. Though, mine is made by Modify.

The piston I have has one teeth removed and fits very well with Riot gears.

I think the shimming of Riot spur gear is a bit tricky. It can be shimmed quite easily too tight.

I've been upgrading my internals over the past week. I was having trouble with the motor getting hot which turned out to be some binding as spur gear was pushing the piston past the last tooth. I also added some padding to the cylinder head and adjusted the AOE.

 

I'm really interested if that AUG/G36 head will work.

Was there ever a solution found for a non functioning hopup ? I tried changing the bucking and still no results. The hopup is working , looked at it with the barrel removed.

 

I'm going to say this ONE MORE TIME. DAMN. The solution is not a conventional bucking. Buy either a PDI W Hold Bucking or KWA 2GX Bucking, I prefer and recommend the PDI. I have it and under half way on hops a .25 perfectly.

Both of these seem to work great , from the reviews, but it still doesn't solve the problem of the hopup not functioning. There must be some people out there with hopups that work fine, I was looking for more of a solution to figure what is wrong with the ones that are malfunctioning and fix it.

May not know the situation, I could barely hop a .2 before I replaced the bucking with the PDI one. This may be the problem they are having.

The gun has amazing externals, but internally its nothing special. It has a lot of gimmicks and cool features but in my opinion lose excitement fast. I'm already selling mine, but a large number of people love their ACRs, sadly I'm not one of them. But I wouldn't base your decision off my opinion.
