usspfnorman Posted September 20, 2012 Report Share Posted September 20, 2012 Hey guys finally got my krieger barrel in for my build and with the gas block on it from krieger, when i put the barrel in the upper theres about a quarter inch gap between the end of the rail and the block. I was wondering if anyone knows of a longer block that will either be flush with the rails or go slightly under the rail?Chris Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted September 20, 2012 Report Share Posted September 20, 2012 how about some pics to help us a little more, and money restrictions ;) Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted September 20, 2012 Report Share Posted September 20, 2012 Pictures will work best...What "rail" did you get? **Nevermind, I missed the titleFrom the way you are describing your rifle I think I understand what you are trying to do. Take a look at the pictures I put together for you, and tell me if I'm close. The top picture should be similar to what your rifle looks like now. The second and third pictures are what you would like your rifle to look like?? Quote Link to comment Share on other sites More sharing options...

Jgun Posted September 20, 2012 Report Share Posted September 20, 2012 Since the title of his original post says Mono rail, I am understanding that the location of the gas block shoulder on the Krieger barrel is slightly forward of the front of the Mega's mono rail. I would think the only options here are going to be a custom gas block, or a different barrel. I'd go for the custom gas block. It would be a shame to not mount the Krieger.

usspfnorman Posted September 20, 2012 Author Report Share Posted September 20, 2012 Sorry I'm currently at work so no pics right now but Robocop you've nailed it. The top piç of the 3 is exactly what it looks like when installed with the little gap between the block and the rails. The second one in the pic is what i would like to have so that means a slightly longer gas block. The rails are sadly not long enough to cover the block which would be ideal like in the bottom of the 3 but krieger wont make a mid length gas system on an 18 inch barrel in 308.

edgecrusher Posted September 20, 2012 Report Share Posted September 20, 2012 ok, now we know what we are dealing with <thumbsup> what gas block are you currently using? what is the shoulder length of the gas block area ( not sure if that is the proper terminology?)lets do this! 8) Quote Link to comment Share on other sites More sharing options...
usspfnorman Posted September 20, 2012 Author Report Share Posted September 20, 2012 I dont really know where or how to measure that, and i currently cant right now I will in about 5 hours when I get home.Right now its currently the rather large gas block that krieger provides.Unforgiven, I also like the look best when the rail covers the block thats why I did it on my rra 223. I have a pic from my phone, not that great but the best I can do as of now. Disregard the saiga in the pic it wasnt done in the pic but I got it finished now.

Robocop1051 Posted September 20, 2012 Report Share Posted September 20, 2012 I really hate being the bearer of bad news. I hope that someone here will have a differing answer for you.Since you bought the Monolithic upper, you are stuck with the one single length of rail system. The Mega is (for whatever reason) just a hair shorter than a standard Rifle Length Gas System.If you see the picture below, you will see a shoulder is cut on your barrel. The gas block comes right up to that shoulder and does not go over it (at least I have never seen one that went over it). They make longer gas blocks, but they extend in the direction of the muzzle, not towards the rail. The only way to conceal the gas block, would have been to get the mid-length gas system.There is a small amount of hope... BUT there are a few $$$$ involved...Check out the VLTOR Tower Sights and the PRI Flip Sight gas Block . These sights won't fix or cure your issue, but they will obfuscate the situation a bit.

Jgun Posted September 20, 2012 Report Share Posted September 20, 2012 usspfnorman, Can clarify for me, are you saying that you have a Mega monolithic upper? or is the picture you posted, of what appears to be a YHM rail, the gun in question?

Jgun Posted September 20, 2012 Report Share Posted September 20, 2012 I bet it would be possible to modify one of the longer low pro gas blocks so that you could have it overlap the gas block shoulder of the barrel. aside from cutting the shoulder clearance to offste the gas block back, you'd also need to drill a new gas port hole and gas tube roll pin hole further forward in the gas block, and then you'd be able to have the gas block cover the exposed part of the gas tube.

usspfnorman Posted September 21, 2012 Author Report Share Posted September 21, 2012 No the pic i posted is of my 223 to show unforgiven since he sad he liked that look. I dont have any pics of my build yet. Quote Link to comment Share on other sites More sharing options...
usspfnorman Posted September 21, 2012 Author Report Share Posted September 21, 2012 Robocop your right I completely overlooked that lip on the barrel. Do you think a company could custom make one that would work or am i just gunna have to live with it. For some reason I think everytime I see my rifle when its done I'm gonna see that gap first.

tolbndfishin Posted September 21, 2012 Report Share Posted September 21, 2012 I havent done what i'm about to suggest, but we're brainstorming, so why not. To cover the gap (cause i'm completely with you there lol) you could get something manufactured that actually extends your handguard a bit. With the correct size Aluminum tube, and turned to fit inside of the existing tube with some way of expanding the fit (for a tight friction fit), or recessing a couple screws through the monolithic tube into the extension. You could probably get that manufactured long enough to cover the gas block, or even play with the shapes a little, if the machinest is willing and capable, so it's a sort of "cradle" for the gas block that might not cover it on the top, but obscures it on the sides and bottom. Just trying to get the creative imagination going.Russ Quote Link to comment Share on other sites More sharing options...
usspfnorman Posted September 21, 2012 Author Report Share Posted September 21, 2012 That is a thought. I think I'm gunna call megas machine shop tomorrow and pitchm the idea of making me a custom gas block that will seat over and passed that lip and end up flush to the rail. Maybe if enough people have ran into this problem they'll add it to there product line. Quote Link to comment Share on other sites More sharing options...
unforgiven Posted September 21, 2012 Report Share Posted September 21, 2012 Hey brother usspfnorman like the look of that rifle <thumbsup>thanks for pic, I got the top of my 14.5 [magnifier,EoTech,over MBUS set up like that but with MagPul handguard.I try to post pics in black rifle don't want to jack you'r thread.

washguy Posted September 21, 2012 Report Share Posted September 21, 2012 Hi Uss Well thats a damn shame! the kewl factor of the mono is the clean unbroken lines of the rail.. of course there are other good things about having a mono....my mono uses the Rainier which is middy gas. I would go with what Robo said ...get a flip up sight gas block, if it can be done....that would look good :) Wash Quote Link to comment Share on other sites More sharing options...
usspfnorman Posted September 21, 2012 Author Report Share Posted September 21, 2012 Unforgiven, I dont think I would ever think of gun porn as hijacking a thread :) Wash you may be correct. I'm gunna call megas machine shop and pitchm my idea. I feel like I cant be the first person with this problem. Too bad krieger wouldnt make a barrel with a mid gas system this could've all been avoided. But i wanted a krieger barrel and figured I just would have the gas block uncovered. But I didnt think thered be a gap there. Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted September 21, 2012 Report Share Posted September 21, 2012 what about a cheaper method, since we are brain storming, locking style rail covers that you mount extending a bit. I know it may look funny but it may only cost 15-20 bucks to try out. good idea about contacting Mega, but keep in mind they no longer make the mono, so making a part that has limited longevity may not be profitable enough for them. try to take a measurement to see how much more real estate you need covered.

edgecrusher Posted September 21, 2012 Report Share Posted September 21, 2012 LMT sued them over copyright infringement, so they decided to stop instead of fighting it out and go in a different direction…. with a new yet to be unveiled direction.I have a matched gtr-3h set thats sweet, so I can't wait to see what they do. A top manufacturer in my book, and not too many here would argue! Quote Link to comment Share on other sites More sharing options...
