Not knocking the riser...
Brian from CA wrote on August 10, 2015:

But the shipping to receive this was the longest shipping ever. Figured maybe 5-7 days, but instead it took 16 days. So what I am understanding is that usps first class package service takes that long. No offense to primary arms as their prices are great, but shipping time is awful. Can't review said purchase as I haven't had a chance to put it to any use as I just received it today, and don't have time at least until a week and a half from now.

it was a well designed product, it just sat a little higher than i thought it would. it sat a little less than 1/8 of an inch above natural plain of rifle, which turned me off to the design.

Arms#40L-F fitment issue
j. castanaga from NV wrote on August 10, 2015:

With the YHM picatinny clamp on gas block, being short in height you will need this YHM Riser. The Arms front sight is long on the riser base and the corners of the clamps will impede fitment. You will need to hack the corners off to make it fit and seat the ARMS 40L-F front sight right. Update: even with the riser on the yhm 0.625 gas block it is still too low to be on the same plane with the railed upper receiver.

Ordered the gas block riser for my CMMG M4LE that has a low profile gasblock. Fits perfect and is very high quality. Will definitely be using Yankee Hill products again in the future. Primary got my order out quick and it arrive within the expected time frame. First time buying from PA and won't be the last.

As advertised

Purchased this riser (YHM-230) to bring the gas block rail of my dpms oracle to an acceptable level to mount BUIS. Worked perfectly, super fast shipping! The product did have small cosmetic flaw but I use my weapons so... Thanks

Awesome As Always!

Sighted in
Michael C. from VA wrote on August 10, 2015:

I purchased my first AR-15 a few years back with a flat-top gas block. I took my time finding flip up iron sights to install on the rifle. When I did, I realized that the gas block was quite a bit lower than the rail on the upper receiver. This Riser solved the problem quite handily. Sighted in and good to go. Thanks

Works but check your sight first
Bob from CA wrote on August 10, 2015:

The riser came very quickly, and looks well made. However, note that the rail where you attached the sight has only one "cut". The Magpul BUIS Pro uses two cuts, one for the screw and one for a sold bar for stabilization. I had to hang the front of the sight over the edge of the riser. Not the best looking setu, but it works.

Gas block riser was what i needed
