Which buis will fit under my ACOG with a TA51 mount?????

Knight's 300m, Knight's 600m, GG&G MAD are three that will for sure. Some people have been able to fit the ARMS#40 under that combo but some haven't also... where it does fit, the clearance is very minimal.

The 40 will clear if you have a 19S mount.

I'll vouch for that. Just mounted my TA31 yesterday with the 19s. ARMS#40 fits (just fits) right underneath no problem mon.

There are a couple of pics [url=http://www.ar15.com/forums/topic.html?b=3&f=18&t=172833&w=myTopicPop]here[/url]. Most have found (me included) that the ARMS #40 doesn't quite fit with the TA51, you are better off with one of the others mentioned.

Thanks guys. Which is the better of the two the Kac 300 or the GG&G MAD?

The 19s and the Arms#40 fit like a glove.

The GG&G A2 will as well

Of the two you mentioned, I like the MAD better because the plastic aperture in the KAC 300 always ends up lost so you effectively end up with a single aperture size; but they are both pretty good.

The #40 has both aperatures built in and the only sight that bounces beck automatically if hit by your sleeve, branches, etc. The others have to be pushed back into place, not good if you have to shoot and didn't see you sight fell down. The ACOG fits fine over it when used with the previously mentioned 19s throw lever mount. Good shootin, Jack

One of my TA01NSN's in the TA51 bracket will fit over the ARMS #40 on a COlt M4A1 upper receiver. The same #40 will not fit under another TA51... I use the #19S on my ACOG's now anyway, as if the ACOG does (unlikely) go down it is much easier to use the thumb lever to dump it and transition to irons - rather than the rather awkward thumbscrews...
