Plan to upgrade gun; need expert opinions and check-over
 

I have a G&G GR16 R5 which I would like to turn into a dmr/spr.
After quite a bunch of research all over I have these parts in mind. However, I am a newcomer to upgrading and would like expert opinions to make sure that I am not choosing incompatible parts or missing things that I should have (or just completely insane...)

(I know this seems like a lot for a first-timer but I problem solve well...and am a perfectionist...not to mention fairly handy and equipped with tools)



base gun:

completely stock g&g gr16 r5 with 509/520mm barrel
Using Intellect 9.6v 1400mah battery

proposed upgrades:

190mm silencer

- EdGI PSG-1(long) 650mm 6.01mm inner barrel
(I know this diameter can cause jams, but I will invest in some nicer low-tolerance .28/.3g 5.94mm bbs...bioval or bb bastards work so I've heard...)

- Modify bore-up cylinder set (m16a2)

- Modify sp120 spring (is this equivalent/similar to m120?)
(I know the parts of the gr16 can handle up to m130, but for obvious reasons I'd like to stay under the max. However, I also know from Illusion's helpful posts that I need at least an m120 to move the bore-up cylinder)

- Modify bearing spring guide (v2 or v3)

- Prometheus perfect metal hop-up chamber m4/m16

- Systema Hop-up bucking

- SCS



Currently this gun shoots around 350fps. I don't know how much the fps would increase with all this, but if I need to disable full-auto I have no problems with that.

Thanks!

You'd be around 400fps or a bit over if you went with these parts, not that I'm saying it's bad, I've run my CA M24 at 400fps last year and it's a beauty, much better than anything I've set it to over 400fps. Looks good so far, and you'll have better consistancy.

New charger and battery.. I have a G&G Gr 16 R4 Commando and the battery i got with it is ruined cause of the stock charger..

One thing I thought of after I posted, a buddy of mine had a G&G M14 that he set up and used as a DMR, after about 6mths of GOOD use, it'd act up, sometimes shoot, sometimes not, I inspected it and found the stock motor fried a brush, causing it to not cycle when it came to rest at that spot, and wouldn't turn again unless I advanced the shaft a rotation. Eventually it actually caught fire. Also found serious arcing across the trigger contacts, to the point one was literally cut through about 2/3 of the way. So maybe add a better motor to your list, an EG700 will work well and be quiet, and a better set of trigger contacts too.

Thanks for the tip! That does seem to sound like a rather serious risk I'd prefer to avoid.

As for the battery and charger, that Intellect battery I listed is not stock. However I have been charging it with the cheap "smart charger" that comes with it and it doesn't seem to be holding a charge for very long anymore... Unless I just didn't charge it properly last time but that is less likely.
Sooo... Also new battery and charger, though luckily I have a nearby friend with a good one.
