Dec 30, 2009 · The G3K with A2 stock would probably be better to shoot but not so compact/cool looking. The shorter barrel made more noise/blast and with the lower lower cyclic rate reminded me a bit of the sound of an M60. I think the G3K is a better full auto gun than the G3 but the HK33 or 33K is a better full auto rifle than both of them....

Jul 13, 2019 · Thanks, I had him do the G3K and an MP5SD for me and both turned out awesome. For my G3K build I provided the following HK German parts in addition to the HK91A3. - G3K / HK33 forearm. - #18 Locking Piece. <---This was the hardest part to find and ran me just shy of $400. - Tungsten filled full auto carrier. - G3K rear sight.

Nov 17, 2024 · I would like a G3K clone for my sear pack. I am looking at two options and would like some guidance. The options I have come up with are: 1. Get an FMP G3 parts kit, PTR reciever, and RCM barrel. Have someone like PCS build it into a G3k 2. Buy a PTR rifle like the PTR91 GI and have it...

Nov 19, 2024 · The idea is to build this SBR with HK21 feed mech, G3K front end, and some modern touches like burst housing, modular handguard, welded picatinny rail and modified MG3 drum attachment. For compliance, make sure to have Form 1 approved in hand before starting and stay within 922R. For major parts, you would need:

Jan 6, 2010 · The first G3K's I recall were made in @ 1972 maybe and they come usually standard with 1/10" rifling though I recall some we also made with 1/12". The first examples came with the standard metal "SEF" select-fire trigger group used with the full-size G3 though Navy and 3RB groups were also available later.

Jul 18, 2012 · The splines/indents can be "moved" (cut off, thread the inside and then attach on the threaded barrel). The G3K barrel was looked at (assume is RCM who makes nice barrels) but by the time I take a nearly new German HK91 barrel out of a German HK91 and replace with a US barrel one could also sell the HK91 and do a clone build or post ban receiver (the SAR8's were looking interesting for that ;-).

Jul 22, 2009 · The G3K uses the same size G-3 bolt carrier & group except for a different degree locking piece... You can cut down a JLD PTR rifle to G-3K spec's but understand the G-3K must be registered as an "SBR" on a form 1 or you must have a R-sear for the rifle...

Apr 13, 2008 · Bottom line on the G3K and the 51 is going to be personal preference. I personally love my 51, but I can see the appeal of the G3K as well. Especially as a gun for open country like when I was at Ft Rich(Richardson) outside of Anchorage. I would have loved to have a G3k up there. Probably would have taken a couple of elk with it as well.

Sep 12, 2008 · Anyway, I recently had a guy tell me with great confidence that he and others use a #9 LP when shooting their G3K's with a suppressor. Apparently a #17 LP is the magic bullet for shooting a G3/91 with a suppressor. I believe that's common knowledge. Anyway, I own a G3K and I plan on testing the #9 LP in the near future.
