Even if you already have telescopic sight fitted, the front sight can still be installed if not both. Reason, batteries can and do fail even when you're not expecting it. These are the best back up at the very least. As a primary sighting system these are the best and faultless flip-up system I've ever purchased. The price cannot be beaten for this kind of quality. ### ⭐⭐⭐⭐⭐ not for 20mm sight rail *by on Reviewed in the United Kingdom 4 March 2024* did'nt fit a 20mm weaver rail/picatinny had to file the sights down where they grip on to the guns rail.to make them fit.other than that good sights ### ⭐ Doesn't fit on 20mm RIS *by on Reviewed in the United Kingdom 30 December 2025* Had to return this as it simply doesn't fit on a standard 20mm rail. Probably could with some sanding but wouldn't expect to have to sand a brand new product, especially at this price point. ## Frequently Bought Together - SUNRIS Tactical M4 AR15 AR-15 Front and Rear Folding Sight flip up Rapid Transition Backup Sight for Picatinny Rail - Afranti Red or Green Dot Sight Riflescope --- ## 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.pe/products/105374451-tactical-m4-ar15-ar-15-front-and-rear-folding-sight](https://www.desertcart.pe/products/105374451-tactical-m4-ar15-ar-15-front-and-rear-folding-sight) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-09-11*
