It mounted easily, and appears in all facets to be well made and the usual Haga designed excellence. The only reason I gave it a 4 star rating is I would prefer one other bolt or fastener in addition to the picatinny screw to ensure the stock doesn't come loose.On A3 Tactical HDA3 Hybrid Folding Stock Assembly for 1913 Picatinny - BlackRRobert S.Verified Buyer5.0 star rating04/11/25Wart HogReview by Robert S. on 11 Apr 2025 review stating Wart HogLove the style, cost has always been a reason I've held back on buying one but they are difficult to find but you had it in stock and it was not an inflated price.On Sharps Bros Warthog AR-15 Lower Receiver - Gen 2MMateo S.Verified Buyer5.0 star rating04/11/25Good quality charging handle.Review by Mateo S. on 11 Apr 2025 review stating Good quality charging handle.Good quality charging handle.On Rainier Industries Avalanche AR-15 Ambidextrous ANC Charging HandleDDavid C.Verified Buyer5.0 star rating04/11/25Great grip and feels goodReview by David C. on 11 Apr 2025 review stating Great grip and feels goodGreat grip and feels good in hand love itOn Nomad 9X Enhanced Frame For Glock 19X Gen 5$323.00Out of stock -
