Question: how sturdy is it when you push your cheek alongside of it?
Document: Bought this for a tapco stock on a wasr 10/63. I have a burris fastfire on a utg forend rail mount. The .7 works well, but the 1.25 is optimal for a great cheek weld. Very sturdy mount on stock. If you're thinking about getting it, do it, you wont regret it
I liked how both sizes came with this bundle. The taller worked perfectly for my rifle and the other for my shotgun. Easy to change out and sturdy as far as I can tell. I've been rough on both and only slight wear. I did get some adhesive cheek rest material on them because the sweat would cause me to slip and lose my cheek weld.
I debated between these and the Magpul PRS stock. The Magpul is definitely a nice product, with very fine cheek weld adjustments, but it adds over an extra pound of weight. Instead, I tried these first on an M4 stock. Overall build quality is good, they snap on well and feel sturdy. It looks great on the stock.
These cheek risers work pretty well. They snap onto the standard 6 position collapsable stock common on a lot or AR15s. I used the shorter one on my AR15 and used the taller one on my Mossberg 500 Tactical.They snap on pretty solidly and do not move around once connected. I would recommend these to a friend. They seem sturdy enough. They are also not too hard to remove for how solidly they snap and stay on.
I have an AR-15 with a scope mounted on the hand rail. That made it difficult to establish a proper cheek weld on the existing collapsible stock. My EMA Stock Set arrived today. I couldn't be happier with this product. It is sturdy and attaches easily. It snaps into place with authority and gives one the feeling that the designers knew what they were doing. The plastic is much thicker than it appears in the photos. It looks like it should last for a long time.
I like that these are well made and not really light. They feel sturdy so far and make sigh alignment a little easier for me.
They really do help with eye positioning for a scope or red dot. Attachment to a standard Tapco collapsing stock is OK, but not real sturdy.
I took a chance that these would fit on the Phoenix Technology adjustable stock that I ordered last year from Amazon. It was a gamble that paid off. They click right into place and work great on my Mossberg 500. They appear to be made in Israel and seem quite sturdy. They put you head in the same spot every time. I clicked them on to my buddies Ruger AR style platform and it worked good there as well. I highly recommend this one!
Very good cheek rest and what I was looking for...
These cheek risers are okay but I don't use them. With the Tapco Intrafuse you don't need extra height for your cheek.
Answer: yes
