The Geissele of Handguards

by

I've been through a lot of high quality rails (KAC, Troy, etc.) but none have had anywhere close to the strength and stiffness that the Geissele MK4 has.
<br>
<br>It's all about the longer barrel nut in combination with precise tolerances that I've NEVER seen in any other rail system. The included barrel nut tool worked like a champ. I dimpled my barrel and used some blue Loctite but did not use the bomb proof cross pin. I'll run this through some classes and range sessions to determine if the cross pin is needed. Seems like overkill but its cool that they included it (and very exact instructions).
<br>
<br>The rail system includes a $60 gas block and good quality barrel nut tool. Well written and precise instructions/schematics are icing on the cake and well appreciated.
<br>
<br>I've been running a SSA-E trigger for a while and put the quality and function of the Geissele SMR right up there with their trigger. I'm looking forward to more Geissele products.

Same Price But No More Super Gas Block?

by

Great quality handguard perfect for your high-end build. Seems that Geissele isn't including a Super Gas Block included with their rails anymore, though they aren't charging less. That was a nice add-on that used to made the premium price easier to swallow. Not the value it once was/wp-en.

Beautiful handguard

by

I bought this partially due to others stating that the gas block and barrel nut wrench were included. They are NOT included. You get a barrel nut and the handguard.

Outstanding!

Very nice rail! The quality is top notch and the installation was a snap. Looks right at home on my carbine build. Don't forget to buy the wrench!

Geissele MK4 rail 13.5

by -

The rail is excellent quality as expected from Geissele. Perfect length for a 14.5 barrel. I have a few “G” rails and wanted this one for the pic rail sections at the muzzle end.
<br>No need to add rail sections for pic rail type light mounts.
<br>As with all other Geissele rails I highly recommend them! Just catch them on sale the MSRP is ridiculous IMO.
