Review: Rugged, reliable, quick, accurate, and inexpensive! - I've been running Troy Micro flip sights on my other rifle for about a year now. While certainly fantastic sights, there are two major drawbacks - one: you have to manually flip the sights up by pulling on them, and two: The sight will not fold down correctly if you prefer using the small aperture - the large aperture is in place by default. So when I bought my second AR, a Sig M400 Enhanced, it came with a less-than-stellar rear flip sight that had the same basic functionality of the Troy, but without the button lock. Being that I didn't plan on mounting an optic any time soon, I realized the need for a quick deploy rear sight. That's why I purchased the Magpul Gen 2 MBUS rear sight - and for my usage - it's absolutely perfect. Everything about the sight screams quality. It's quite heavy for polymer, which I wasn't expecting, but still shaved some weight off of my AR (all Magpul MOE furniture to keep it light). It pops up quickly when needed and tuck away quickly when I don't, were zeroed in with my standard A2 front post sight when I received them, and look fantastic on my rifle. I had used and abused a first gen set on a different rifle and they never let me down, so I don't expect this one to either. Magpul is a company known for constantly striving to improve and perfect their products. Don't listen to any naysayers about it being a "cheapo plastic sight" - These things are built like a tank and I actually prefer mine to the Troys I have on my primary rifle. If you need a flip up rear sight and are considering buying this - just do it - if you don't like it - return it or sell it on Ebay for a minimal loss. Review: Wouldn't hesitate to buy another - I love this sight to death. It's so tight to put on the rail I had to apply lube to the rail itself, tight tolerances are a good sign of quality manufacture. Feels solid, not flimsy or wobbly. Spring retention ensures that after each shot it returns to zero. Also, the square top of the sighting ring makes obtaining accurate aim faster. I have an A3 type rifle, and the standard A2 front sight with it's dog ears protecting the front sight blade: point directly to the squared edges of this rear sight's peep ring. Which actually makes acquiring the target seem easier and faster than if it were a perfect circle rear sight ring. Maybe it's psycho somatic where it's purely me, but it quite honestly seems faster on target than metallic orb rear peeps. the square top of the sight ring, purely objectively to me at least, seems to aid in my finding the center with the front sight blade because the dog ears protecting the blade have an extra frame of reference by branching off towards the square radii left and right of the rear peep. Could be my imagination: but I love this thing. It's solid, tight, retains zero, folds -REALLY- low (which is great) and what I like most: super light weight. I don't like quad rails and hanging off 5 pounds of junk on my rifles. I don't put anything on one of my rifles unless the added capability the accessory brings justifies the weight it brings. I like an Ar-15 carbine to be light and fast, transition target to target quickly. I wouldn't hesitate to put one of these on any pic rail that needs a backup rear. Be it a full fledged A3/A4 combat rifle or a $5k race gun that has to have a rear sight to qualify for a division or specific course of fire. Fits tight, holds zero and weighs next to nothing: you can't go wrong with one of these. I have -NOT- had hands on experience with the mbus II FRONT sight, only the rear: so I cannot offer an informed opinion about the mbus front sight. I can say with relative confidence, I have a high opinion of magpul products in general and if the front sight is of equal quality to their rear sight - I wouldn't hesitate to use that either. I cannot however, give first hand account of what the front sight is like. I can say that -MY- mbus II rear sight is terrific, and that it's my go to choice for any pici-rail gun platform that's in need of a backup rear. ## Features - Impact resistant polymer construction provides light weight and resists operational abuse - Spring-loaded flip up sight easily activated from either side or by pressing the top - Detent and spring pressure keeps sight erect but allows for unobstructed folding under impact, etc. - Clamps to most any MIL-STD-1913 Picatinny/STANAG 4694 rail and provides the same height-over-bore as standard A2 irons - Protective wings shield the spring-locking A2 front sight post; Elevation adjustment tool included, but most aftermarket A2 front sight adjustment tools may be used as well ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004RR0N8Q | | Best Sellers Rank | #16,629 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #11 in Airsoft Gun Sights | | Brand | Magpul | | Brand Name | Magpul | | Color | Black | | Compatible Devices | Rifle | | Customer Reviews | 4.8 out of 5 stars 4,944 Reviews | | Global Trade Identification Number | 00873750004358 | | Hand Orientation | Rear | | Included Components | Magpul MBUS Flip-Up Backup Sights, Black, Rear Sight | | Item Dimensions L x W x H | 4"L x 6.6"W x 1.2"H | | Item Display Dimensions | 7.75 inches | | Item Display Weight | 2 pounds | | Item Type Name | MBUS Sights | | Item Weight | 1.44 ounces | | Lens Color | Black | | Magnification Maximum | 1 x | | Magnification Minimum | 1 x | | Manufacturer | Magpul | | Manufacturer Part Number | MAG248-BLK | | Material Type | polymer or aluminum | | Model Name | MBUS Flip-Up Backup Sights | | Model Number | MBUS | | Mounting Type | Picatinny Mount | | Number of Items | 1 | | Number of Packs | 1 | | Product Dimensions | 4"L x 6.6"W x 1.2"H | | Product Style | Rear Sight | | Reticle Type | Crosshair | | Sport | Hunting | | Sport Type | Hunting | | Style | Rear Sight | | Team Name | Magpul | | Thread Type | Picatinny | | UPC | 711091345887 789632564127 757183089864 873750004358 | | Unit Count | 1 Count | | Warranty Description | Limited lifetime warranty | ## Product Details - **Brand:** Magpul - **Color:** Black - **Compatible Devices:** Rifle - **Item Weight:** 1.44 ounces - **Magnification Maximum:** 1 x - **Magnification Minimum:** 1 x - **Material:** polymer or aluminum - **Product Dimensions:** 4"L x 6.6"W x 1.2"H - **Sport:** Hunting - **Style:** Rear Sight ## Images ![MBUS Flip-Up Backup Sights, Black, Rear Sight - Image 1](https://m.media-amazon.com/images/I/61O58zntAjL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Rugged, reliable, quick, accurate, and inexpensive! *by C***P on December 8, 2012* I've been running Troy Micro flip sights on my other rifle for about a year now.

But magpul are cost effective and in a drop test they seemed more durable than Diamondhead/Troy. Not only did they retain zero better than the others, but they seemed to handle impact better than metal. Taken from an article on KitUp "In order to test whether certain popular BUIS would still be serviceable after taking a hard hit, I attached three different types of BUIS - Troy Industries, Magpul Industries and Diamondhead USA - to an AR-15 rifle chambered in .300 AAC Blackout weighing 7 pounds and dropped the rifle upside down from a height of 5 feet onto a concrete surface. Other portions of the rifle were protected from damage, and each set of BUIS took a solid hit from the drop. The ammunition used was Remington Premier Match .300 AAC Blackout 125 gr OTM. Each sighting device was installed according to the manufacturer's instructions, then points of impact was established from a stable shooting position at 25 and 200 yards. After the drop, the rifle was fired again, and any change in point of impact noted. The first BUIS dropped was the Diamondhead. At first, damage appeared cosmetic only; however, the apertures could no longer be rotated, windage could not be adjusted, and there was a definite cant to the BUIS. Point of impact shifted approximately 16 MOA. We contacted Diamondhead with this result. They replied that a newer version was available which was more durable. We offered to test the new model but production issues meant they could not ship one to us. Next came the Troy sight. Cosmetic damage was apparent, but the sight could still be operated normally. Point of impact shift was approximately 3 MOA. The last set of BUIS was the Magpul MBUS. Damage was purely cosmetic and the sight remained fully functional. Point of impact shift was less than 1 MOA. Unlike the other sighting devices, a second drop was performed. Results did not change, and the sight remained functional." Now my personal experience with these is on my M&P15-22 but I'm ordering an additional MBUS for the AR I am building. They are really good quality, just make sure you don't get a PTS sight from a bad retailer. ## Frequently Bought Together - Magpul MBUS Flip-Up Backup Sights, Black, Rear Sight - Magpul QD Sling Swivel - Magpul MS1 Two-Point Quick-Adjust Sling --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kg/products/1836888-mbus-flip-up-backup-sights-black-rear-sight](https://www.desertcart.kg/products/1836888-mbus-flip-up-backup-sights-black-rear-sight) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-29*
