I have seen no degradation after 1000 rounds, but a shotgun is a different animal. **Q: What base height comes with the scope?** A: Yes **Q: Will it fit Henry golden boy** A: No. But it's not the fault of the scope. The goldenboy does not have the means to mount a scope to the receiver as the rest of the Henry rimfires series do. **Q: does this have an etched reticle** A: Yes it has a nice, sharp etched reticle that can be seen clear without illumination or enhanced with red or green illumination. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great inexpensive scope *by T***S on Reviewed in the United States on October 11, 2021* This is not an EOtech or Trijicon. That being said this is a phenomenal inexpensive scope. This is a perfect scope as a starter or for an inexpensive build. I mounted the Monstrum 3-9x32 AO on a custom 10/22 to be replaced eventually. Pretty sure I’m going to keep this one on it. Parallax is adjustable which is great at this price point. Zoom is low enough for inside 10-15yards and out to 200. Zero has held after 4-500rnds of .22, minimal adjustment. Eye relief is pretty good, didn’t measure but you can use with an AR. Glass is decent, not like my high end ones, but that’s why they’re 10x the price. Windage and bullet drop work well and are consistent. Illuminated cross hairs are nice in both green and red. Reticle is great. The zoom throw is great, large enough and replaceable if you wish. Very well built scope, I’ve beat it up pretty good and it’s delivered consistently. All and all, a great deal for the money. I’m pretty sure it would hold up to recoil on AR. Well made piece of glass as a starter or otherwise. Do not hesitate ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars VERY Heavy! But, a GREAT SCOPE for the money! *by S***K on Reviewed in the United States on April 14, 2024* I'm 74 and NEVER understood someone spending as much for a scope as for the rifle! So, in my MANY years, I've developed a 'formula'......NEVER SPEND MORE FOR A SCOPE THAN YOU DID FOR THE RIFLE!!! Simple! My new .22 MAG Rossi RS22M will cost around $250. So, I've got this scope for less than 1/3 the price of the rifle. Fits well with my 'formula'. The scope is HEAVY (inexpensive scope, REMEMBER!), but Fit, Finish, and Functionality are right up there with scopes I've paid 10X for!. For the bucks, this little HEAVY jewel just can't be beat! Very highly recommended. And, it really looks good in FDE!!!! And, it's heavy! ### ⭐⭐⭐⭐ 4.0 out of 5 stars Good value for the money *by S***H on Reviewed in the United States on February 21, 2024* Keep in mind this is a cheap scope and should be rated as such. I have it mounted on a 15/22 and I believe that is best for this scope. The finish is good and the lenses are clear until you are on full zoom. I sighted it in at 50 and then checked the hold over tick marks at 100. The reticle is not very crisp but I do like the illuminated reticle. I believe this is a good scope for a hunting and plinking set up. I would not recommend this for a high powered rifle. Stick with 22 or 223 AR type set ups. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/156543175-monstrum-3-9x32-ao-rifle-scope-with-illuminated-range-finder](https://www.desertcart.pe/products/156543175-monstrum-3-9x32-ao-rifle-scope-with-illuminated-range-finder) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-04-22*
