Customer Ratings & Reviews
I would buy this AR sight again
I love the old school look of the arms silhouette folding front sight. It also flips back nice and neat out of the way. Have you ever held something that makes you think? Wow, this is really well made Very smooth with great machining 5 stars.
great sight/gas block assembly
The ARMS silhouette AR-15 Sights are easy to install, extremely strong, lines up perfectly, easy to use, and, quite frankly, great addition if you want the sight to get out of the way for scope use. I love it. No complaints whatsover!
Great folding front sight, Love it!
I purchased this folding front sight about a month ago. The reason I got it was because my A-2 front sight was slightly canted to the left, and to repair it, I would have had to send it back and have it fixed...I liked the looks of this front sight, so to kill two birds with one stone, I decided to get this front sight to correct the "cant" and upgrade the front sight at the same time. The old ar-15 sight came off very easily, and the new one went on with about an hour's worth of careful work. I had to be careful and make sure the gas port was still lined up with the hole in the barrel. If it's off, I cannot tell because of the rifle functions flawlessly. I am starting sighting my rifle in at the range the next day with the front sight post flush, and the rear sight in the center. Three clicks to the left at the rear sight and three clicks down at the front sight, she's dead on. The AR-15 sight folds easily and flips up easily. Very solid, and I like the fact that it folds away out of the picture with my primary red dot optic mounted. This is the ONLY product out there that works and retains the bayonet lug. All other vendors that have anything similar are perpetually out of stock or back-ordered, and the lug is not there. Buy this sight; you won't be disappointed.
More than happy
These arms folding front sight fits my full-contour barrel just fine. I used with handguard cap, so the included shim was not needed but glad to have it in the parts box. Lined up fine and tightened up correctly. No stripped screws like others stated, nor did it break when tightening. This ar-15 sight is rugged enough to stand up to abuse for over a year of being banged around on the atv, ground, truck, trees, etc. chasing hogs in east Texas. I would repurchase it.
#41-BL Arms folding front sight
As usual, A.R.M.S. has provided another incredible piece of machining. I have never been hung up on the look of the standard AR triangular front sight, though I know many people who are. I just purchased one of these for a "traditional" style build, and I am amazed. I have used flip up sights from other quality manufacturers, and this one is by far the most solid of them all. Where other companies rely on a detent to hold the sight up, this one actually uses the geometric strength of the triangle to hold it in place. You can bang on the front or the rear of it, and it does not move at all! Yet one correct downward push on the right place (directly behind the sight ears), and you can easily fold this sight down with a single finger or thumb! It really is slick, and should be almost impossible to fold accidentally! In addition to having a near-perfect look, having the mounting tabs for a correct front sling swivel is a purist's dream. If you want your AR to look like an AR and not some mutant, but still wish you could get that sight out of the way, then this is the AR sight for you, bar none. It's even machined with details that make it appear like the original forgings, a nice touch! The only downsides I could find to this sight are that because of the way it folds down onto itself; it does not fold into a low of a profile as a GG&G or Y.H.M. front sight. Also, if you are the type who uses a level to make sure your front sight is square to your receiver, you will find there is hardly any place on this sight you can use to level with. As such, you may want to use a gas block aligner like the one from UniqueTek that Brownells sells (100-015-040WB), though I always seem to have troubles when I try to use those myself (ha haha). As a final nod to A.R.M.S. quality, this sight not only included the wrench, it included the proper barrel shim to use if you need to install the sight without a handguard cap. Definitely, a valuable thing to keep in your spare parts bin for later if you don't use it now! The wrench and screws were both fines on my unit, as expected. It doesn't take a lot of torque to make this thing stay in place forever! Overall, I still prefer my sights to fold a little lower (and cost a little less), but I would not hesitate to buy another one of these if I need that classic look and no-compromise performance! Five stars all the way!
ARMS Silhouette folding front sight
I still think this is a great folding front sight, but two years from the purchase, I have had to take the sight on and off a couple of times. Today the hex screws stripped. I called A.R.M.S. directly, and they are sending me replacements free of charge. If that strip I will just go and buy some higher grade screws at the hardware store.
Careful with this choice
Yeah, the sight looks great and installed easily, however it didn't secure tightly on my PSA .75 barrel. I had to shim it to make it grab the barrel tightly. Also, the bolts that came with the unit stripped out (not cross-threaded) due to trying to get the FSB mounted tightly before I made a shim. Ended up having to locate proper harder metal bolts to mount the sight properly. Bayonet lug is purely cosmetic and will not hold a bayonet. The sight works perfectly as it is intended. It deploys easily and can be collapsed with the touch of a finger. Great design but lacking in it's final presentation due to sub-par mounting hardware and the slightly over-sized bore that would not permit a secure clamp. Overall, I'm fairly disappointed in the product, I also found out from reputable sources that the owner of A.R.M.S. is not only an unpleasant individual, but also makes contributions to very liberal anti-gun organizations so I will not be buying any A.R.M.S. products in the future.
Being a sentimental traditionalist the bayo lug is for me a must (having a midlength upper) but with an A-4 upper the fold down sight is primo with optics, Nikon M-223. Easy to install, just a 1/16 drift punch small hammer, hand guard removal tool and a pre removal measurement of where the gas port is.Set the old iron sights dead on at say 50-75 yards then bring the allen key to the range, a fewrounds through the A.R.M.S. 41BL then adjust the sight accordingly.Excercise all safing of the weapon before adjusting.
