3vi1-D4n Posted April 13, 2015 Report Share Posted April 13, 2015 Yeah...ditch a perfectly fine VFC M4 for a promise of a great VFC HK417 for a bit of the 308 action or wait for a WE SCAR-H? VFC M4s with steel outer barrels are generally accurate enough as DMRs, so I have been eyeing out a spare upper to build a MK12....What to do? Quote Link to post Share on other sites
christhesecond Posted April 13, 2015 Report Share Posted April 13, 2015 It's the most fun I've had with any airsoft rifle put it that way. It's the highflow valves that really bring it to that level. Most places are out of stock I think but you get similar results if you Dremel them our yourself. The problem, as has been pointed out to me by a friend, is when the valve stem is depressed; the thicker part of the stem protrudes too far into the port and blocks 75% of the area of the holes if that makes sense.

Bada Bing Posted April 13, 2015 Author Report Share Posted April 13, 2015 I can concur on the increased efficiency with ramjet valves. Here's quick snaps of the broken hop up. Could have broken perhaps because I've disassembled it so many times testing out various setups that I may have been a little rough and snapped off both halves? I don't know. Good job spare parts are pretty cheap. Quote Link to post Share on other sites
Zereck Posted May 13, 2015 Report Share Posted May 13, 2015 A few days ago I installed a Crusader anti-rotation link on my 417 and I noticed that now I can put the gun on safe even uncocked. Strange as the gun works perfectly fine on safe, semi and full-auto, no problem with it, just weird. During installation I simply pushed the old pins out with the new ones while making sure nothing jumped out of place. Quote Link to post Share on other sites
vilerk Posted May 13, 2015 Report Share Posted May 13, 2015 Well, now you're 417 is even more realistic Reference(bottom of page 7): http://hk-usa.com/wp-content/uploads/MR762A1-Operators-Manual-04312014.pdf 1 Quote Link to post Share on other sites

Bada Bing Posted May 29, 2015 Author Report Share Posted May 29, 2015 (edited) ^ That's impressive! Say... What do you guys make of this? I need a different perspective, I believe this is the cause of my double feeds/jams. Edited May 29, 2015 by Bada Bing Quote Link to post Share on other sites
BioRage Posted May 29, 2015 Report Share Posted May 29, 2015 VFC 417 is the hardest kicking GBBR I've used, it also sounds very loud and is sweet. If I didn't play CQB as my main, I would of grabbed this. (Yes kicks more then ghk g5) Quote Link to post Share on other sites
Zereck Posted May 29, 2015 Report Share Posted May 29, 2015 ^ That's impressive! Say... What do you guys make of this? I need a different perspective, I believe this is the cause of my double feeds/jams. Yeah I have the same problem with the 417 and the MP7 both VFC, I guess it's common with the VFC gbbrs. To quote Devil-Dan from the VFC MP7 topic: "In regards to jumpy issues with auto, its because the hammer is falling before the bolt has returned to battery. Usually due to bolt bounce. Two solutions: - Increase strength of return spring. This fixed the VFC MP5 inconsistent auto issues - Use an anti-bounce buffer (made by AABB) for VFC M4/416/M27 though dunno about 417." Unfortunatelly there are no stronger recoil spring or hammer spring avaible yet for the 417. 1 Quote Link to post Share on other sites
L2E Posted May 29, 2015 Report Share Posted May 29, 2015 Absolutely correct Zereck. However, this bolt bounce happens on almost all GBBR M4 variations just the difference is that the other platforms (GHK, WE, VT, etc.) nozzle maintains a seal with the bucking during the bounce so no double feed. In the 5.56 variants, I typically use a real standard AR15 buffer and I would bet that the HK buffer would work in this case; however, it is $129 in the USA. Quote Link to post Share on other sites
Atsalakotos Posted May 30, 2015 Report Share Posted May 30, 2015 Well I have noticed the bolt bouncing a lot more than any 5.56 AR variant I have owned... But I rarely get misfeeds as the nozzle stays in place. I would suggest removing the nozzle and polishing the inside of the bolt carrier, as it is painted and with use the paint wears off unevenly causing the nozzle to move sluggishly. (And of course lubricate the nozzle oring properly) Quote Link to post Share on other sites
christhesecond Posted May 30, 2015 Report Share Posted May 30, 2015 I wonder if this is in fact the same issue with the vfc mp7 as I've been having no end of problems with that recently. Quote Link to post Share on other sites
Bada Bing Posted May 30, 2015 Author Report Share Posted May 30, 2015 Thanks guys. I've lubed the nozzle o ring and that seemed to have stopped the nozzle bouncing out with the carrier. Having some misfiring though. Shot one fine, shot two dry and shot three two bbs fly out. Grr! All I want to do is use it in game. Quote Link to post Share on other sites
christhesecond Posted May 30, 2015 Report Share Posted May 30, 2015 What hop rubber are you using mate? Quote Link to post Share on other sites
Bada Bing Posted May 30, 2015 Author Report Share Posted May 30, 2015 New improved VFC bucking. They changed their design ever so slightly. Quote Link to post Share on other sites
christhesecond Posted May 30, 2015 Report Share Posted May 30, 2015 Yeah I have one of those fitted myself. Quote Link to post Share on other sites
Bada Bing Posted May 31, 2015 Author Report Share Posted May 31, 2015 (edited) It's actually quite decent. Compared to the old one, bbs seem to fly arrow straight. Well that is when only the one bb is in the chamber before firing. I'm trying to compile a list of parts that could effect my double feed issues. 1. Bolt carrier has marring along where the striker release tab has ground along it. 2. When using the charging handle to slowly seat the carrier into battery the nozzle/or carrier(due to part 1?) sits a little low until the lugs catch the barrel extension and jumps in as it closes. Sometimes it doesn't jump up and just stops just in front. Happens with and without mag. 3. Barrel extension has deformed somewhat and that's negating the nozzle seating, although nothing found upon inspection. 4.Sounds a little mad but the charging handle could have a slight twist causing the carrier to turn at such an angle. That's about as much I can think of right now. I've got 3 nozzles and 2 of them have worn on the bb follower on one particular edge.

christhesecond Posted May 31, 2015 Report Share Posted May 31, 2015 I had loctited the body pins in the hold all the pins in but forgot the one on the charging handle so that and the release catch went walkabout today. Quote Link to post Share on other sites

(And of course lubricate the nozzle oring properly) That is b/c AR's come with buffers with anti-bounce weights. You start to see the issue when you run SBR's in full-auto using just a standard buffer. Your off the shelf AR15 will most likely never encounter bolt bounce...

Zereck Posted June 1, 2015 Report Share Posted June 1, 2015 Do real steel M4 charging handles fit the 417? I really want to switch to something better as it tends to fly in my face at last shots. Quote Link to post Share on other sites
BioRage Posted June 1, 2015 Report Share Posted June 1, 2015 They will fit, but you will most likely have to mod some parts. Quote Link to post Share on other sites
Atsalakotos Posted June 2, 2015 Report Share Posted June 2, 2015 A normal AR charging handle will NOT fit the Hk417, there is a huge size difference in the bolts both in length and diameter. Here is a pic i took in comparison with an old AGM M4 bolt and charging handle I had. Hope this helps. 1 Quote Link to post Share on other sites
hitmanNo2 Posted June 2, 2015 Report Share Posted June 2, 2015 RS charging handle is $200. Always that option heh. Quote Link to post Share on other sites
Zereck Posted June 2, 2015 Report Share Posted June 2, 2015 I have seen AR15 charging handles for 20$ or less but I guess I have to look for a different option. SR25 charging handle maybe? Quote Link to post Share on other sites
