{"product_id":"dpms-sba3-lower-build-kit-w-trigger","title":"DPMS SBA3 Lower Build Kit with Trigger – AR-15 Platform","description":"\u003cp\u003eThis DPMS lower build kit provides the essential components needed to complete an AR-15 lower receiver, including a factory trigger assembly and SBA3 pistol stabilizing brace. Designed for builders assembling AR-15 pistols or rifles, this kit streamlines the parts-gathering process by bundling the fire control group, lower parts, buffer system, and brace in one package. Ideal for home builders comfortable with basic AR assembly or those completing a stripped lower receiver.\u003c\/p\u003e\u003cp\u003eComponents include mil-spec fire control parts, standard lower receiver hardware (trigger\/hammer pins, safety selector, magazine catch, bolt catch), carbine-length buffer tube assembly with spring and buffer, and an SBA3 adjustable pistol brace. The SBA3 features a split design for improved fit and five positions of adjustment. Installation requires standard AR assembly tools—punches, hammer, and an armorer's wrench. No permanent modifications or gunsmithing required for drop-in installation on mil-spec lower receivers.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Complete Lower Build Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Firearms:\u003c\/strong\u003e AR-15 Mil-Spec Lower Receivers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Trigger Assembly, Lower Parts Kit, Buffer Tube\/Spring\/Buffer, SBA3 Pistol Brace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuffer System:\u003c\/strong\u003e Carbine-Length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrace Adjustment:\u003c\/strong\u003e 5 Positions\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e Drop-In with Basic AR Assembly Tools\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DPMS","offers":[{"title":"Default Title","offer_id":48301580779775,"sku":"DPMSDP51655152953","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/0434\/3807\/files\/5794236.jpg?v=1773889452","url":"https:\/\/doublestackstore.com\/products\/dpms-sba3-lower-build-kit-w-trigger","provider":"Double Stack Store","version":"1.0","type":"link"}
