I know, I know...but I recently saw a well put together AK on this site with the basic intrafuse handguard along with a stubby VFG and it looked really good. It was complimented with an Ultimak rail and red dot.
Anyone running this combination? I'm wondering if there are any horror stories with the intrafuse or whether there may be fitting issues with the Ultimak rail. Thank you! |
I run the full Tapco stock set on mine in OD green with the folding stock.
It works pretty well and the right folding stock does not impeed using it in the folded config... so it can double as a AK pistol or car gun. My only complaint is my lower rail cover does not want to stay in place like the Tapco cover for the Fusion handguards on the AR. But I prefer having the folding pistol grip anyway so not a problem... I did not like the upper rail but obivously the ultimak would be a superb choice to replace the Tapco upper handguard. |
This one?
The Tapco lower hand guard is working out well. Be aware that if you use an Ultimak, the flimsy heat shield has to be removed and a little trimming with a Dremel is required to make it clear (1) the Ultimak U-brackets and (2) the four screws that hold the two U-brakets to the Ultimak. No big deal and is quick/easy to do with a Dremel. The hand guard is plenty thick and sturdy so I don't think the removal of the "heat shield" is going to make any difference. BTW, I'm giving the IOR micro RDS a try in place of the larger/heavier Aimpoint CompC3. I'll post my findings once the IOR RDS arrives and I have a chance to mount it. |

That there, sir, is the beauty I was referring to. Thanks for the info on installation. I'm going for it! |

Thanks! More info -
I've owned a Krebs Custom AK103k for about 5 years now and it is a fine rifle. The rifle came with the standard black plastic stock with metal butt plate, which I was never comfortable with. The length of pull was OK, though I prefer a shorter length. The butt of the stock was short (in height) and curved out on the bottom. Since I hold the rifle high on my shoulder (as opposed to crunching down to use the sights), the stock was never really comfortable. After a bit of research, I decided to install a new stock using the following parts; - ACE Internal Receiver Block - ACE Folding Mechanism with integrated AR15 type Stock interface - Magpul CTR stock (mil-spec) Installation of the internal receiver block requires the removal of the rear tang. This is a straight-forward process using a hack saw, a file and some black paint for touch-up. In my case, the receiver block required some fitting. Specifically, the top of the tangs needed to be filed down a bit to allow the block to slide all the way in. I did the filing a little at a time, test fitting along the way. Once the block required only a few light taps to fully seat, it is secured with the supplied machine screw and nut on the top and the pistol grip screw on the bottom. The folding mechanism bolts up solidly to the receiver block. The next step was to cut down and secure a mil-spec buffer tube to the folding adapter. Since I wanted the CTR to lock into the forward-most position with little to no gap between it and the folding adapter, I decided not to use a castle nut to scure the tube to the adapter. After taking some measurements to determine how much I would have to remove from the tube, I made the first cut with a Dremel and then went to work with a file. The goal was to get the tube cut to just the right length so that when it was hand tightened into the folding adapter as far as it would go (bottom the threads), it would be timed perfectly with the rail at the 6 o'clock position. Once I got it to this point, I cleaned the threads with brake cleaner and applied a generous amount of Locktite. Finally, once the tube and stock were assembled to the rifle and I verified all was straight, I drilled through the adapter and buffer tube and secured them together with a roll pin (see the second photo below). Using this procedure, the tube is very well secured to the folding adapter with no chance of coming loose. The stock modification worked out really well. With the stock folded to the side, the OAL is 26-1/4 inches keeping the BATF happy. With the stock folded out and the CTR locked in the front-most position, the rifle's AOL length is 34 inches, including the extended Magpul rubber butt plate. The other mod made at this time was replacing the stock front/lower handguard with a Tapco INTRAFUSE that includes a bottom rail so that I can attach a Magpul AFG. This combo worked out well and fit together perfectly without modification. I had a chance to try out the new modifications yesterday at a local carbine match. Overall, the modifications made the AK easier to handle and control. I shot the entire match with the CTR locked all the way forward (12 inch length of pull) which worked out very well for me.

I would hang a light off the left side of the ultimak. |
