| I zero'd my AR and since I have a flat-top, the rear site assembly sits higher than normal. The rear site is cranked as low as possible, and to get the shot group in the black, I had to raise my front site post wayyyyy up (lowering the shot group). I don't know how much more I've got till it unscrews right out, but the fact that it sits wayyy over flush concerns me. Can I get a front site with a higher post ??? |
| Pretty much a standard AR flat-top, from J&T. Stock iron fronts, but like I said, its a flat-top, so the detachable carry handle/rear site assembly sits just a tad higher than normal (1/4" if you do a side-by-side comparison). This means I have to crank the front post higher than normal to get my shot group down into the black from the 50. |

At what distance did you zero your AR? Was it 50 yards? More importantly your rear sight should not be that high. It sounds like your flattop receiver is out of spec or the rear sight is. The only other problem I could think of is you put on one of those Colt M4 barrels with the shorter than normal sight tower. |

1R4, I know you think you are helping but you are not telling us WHO made the "Standard upper" and "no name" carry handle. If it all came from J&T I would send it all back and tell them to send you something that works. If you have mixed and matched and want our help, we will need to know WHO made WHAT. This is not a flame, simply a second attempt to extract more information from you. -elliott If you stick with us, we can figure it out  |
FN does not make flattop uppers or carry handles at all, and could not sell them if they did. FN only produces M16A2s and M16A3s, both of which use the "A2" upper with integral carry handle. The problem you have is common when mixing a slightly taller Colt "M4" detachable handle and a non-"F-stamped" barrel. Colt M4s have slightly taller front sight bases, with a a stamped "F" on the side, and must be used with their slightly taller carry handle. You need a standard-height carry handle. -Troy |
