The invention claimed is: 1. A magazine well extension for a lower receiver of a rifle having a front pivot, a changing contour adjacent the front pivot, a trigger guard and a magazine well, the magazine well extension comprising: a first receptacle part having a distal end and a proximal end which comprises a first wall disposed at the distal end which comprises a top surface, a bottom surface, a first exterior surface, a first interior surface which extends from the top surface to the bottom surface, and which comprises a convex segment adjacent the top surface, a front groove disposed below the convex segment, and a magazine guide disposed below the front groove, the convex segment being configured and dimensioned to conform to a changing contour adjacent the front pivot of a lower receiver; a second wall, adjacent the first wall, which comprises an upper contour, a lower contour which comprises a concave segment positioned above the bottom surface of the first wall, a second exterior surface, a second interior surface which extends from the upper contour to the lower contour, and which comprises a side groove; and a strut, disposed opposite the first wall and adjacent to the second wall, which comprises a first end surface, and an upper surface adjacent the first end surface; the front groove, side groove and upper surface being aligned and connected to receive a magazine well and a trigger guard of a lower receiver; and a second receptacle part which comprises a fourth wall connected to the first wall, and a fifth wall, disposed opposite the second wall and adjacent to the fourth wall, the second receptacle part being joined to the first receptacle part such that the first and second receptacle parts are configured and dimensioned to lock onto a magazine well and a trigger guard of a lower receiver of a rifle and to guide loading of the magazine well. 2. The magazine well extension of claim 1, wherein the first receptacle part further comprises a front grip face, and first exterior surface defines the front grip face. 3. The magazine well extension of claim 2, wherein the front grip face further comprises a saddle connecting two peaks. 4. The magazine well extension of claim 2, wherein the second exterior surface further comprises a side grip face. 5. The magazine well extension of claim 1, further comprising a bore extending into the first end surface. 6. The magazine well extension of claim 1, wherein the top surface is convex. 7. The magazine well extension of claim 1, wherein the concave segment abuts the proximal end. 8. A method of transforming a magazine well of a rifle lower receiver into a fore grip comprising: providing a magazine well extension of claim 1; positioning a lower receiver of a rifle into the first receptacle part; interlocking the lower receiver in the first and second receptacle parts; and fixing the first receptacle part to the second receptacle part. 9. A magazine well extension for a lower receiver of a rifle having a front pivot, a contour adjacent the front pivot, a trigger guard and a magazine well, the magazine well extension comprising: a first receptacle part having a distal end and a proximal end which comprises a first wall disposed at the distal end which comprises a top surface, a bottom surface, a first exterior surface, a first interior surface which extends from the top surface to the bottom surface, and which comprises a front groove, and a magazine guide disposed below the front groove; a second wall, adjacent to the first wall, which comprises an upper contour, a lower contour which comprises a concave segment positioned above the bottom surface of the first wall, a second exterior surface, and a second interior surface which extends from the upper contour to the lower contour, and which comprises a side groove. 10. The magazine well extension of claim 9, wherein the first interior surface further comprises a first segment adjacent the top surface, the first segment being configured and dimensioned to conform to a contour adjacent the front pivot of a lower receiver. 11. The magazine well extension of claim 10, wherein the first segment is convex. 12. The magazine well extension of claim 10, wherein the first interior surface further comprises a planar segment extending from the first segment to the front groove. 13. The magazine well extension of claim 9, wherein the concave segment extends to the proximal end. 14. The magazine well extension of claim 9, further comprising a second receptacle part which comprises a fourth wall connected to the first wall, and a fifth wall, disposed opposite the second wall and adjacent to the fourth wall, the second receptacle part being joined to the first receptacle part such that the first and second receptacle parts are configured and dimensioned to lock onto a magazine well and a trigger guard of a lower receiver of a rifle and to guide loading of the magazine well. 15. The magazine well extension of claim 14, further comprising a coupling element for fixing the first receptacle part to the second receptacle part. 16. The magazine well extension of claim 14, wherein the first receptacle part further comprises a strut, disposed opposite the first wall and adjacent to the second wall, which comprises a first end surface, and an upper surface adjacent the first surface, the front groove, side groove and upper surface being aligned and connected to receive a magazine well and a trigger guard of a lower receiver. 17.
